Truefree B1 - A Bearded Review
Truefree B1 Review - A Bearded Review A no-nonsense review of the Truefree B1 on-ear headphone First Impression The look of these on-ear earphones is... Interesting. They aren't like your regular IEM (in-ear) or headphones (over-ear). These have speakers that point toward your hear canal but sit on your earlobe. There is absolutely no audio isolation with these. If the volume is high enough, others can hear your audio, albeit, it would not be distinguishable by others, but still, they can hear it. Obviously, if you reduce the volume, you'll still hear the audio without others eavesdropping or being annoyed. Feel I personally like how these feel on the ear. Headphones can feel heavy over time. Earbuds can be a pain in the ear. These just hang like clip-on earrings without the pinch. They have metallic shine on the speaker and touch ends with soft silicone connecting them. I don't see any reason why you couldn't wear these for hours, unless you just don't like the feel. A bonus if you wear glasses or hats, these do not interfere with either. Audio Audio Codec-wise, they only connect with SBC (non-HD) or AAC (HD). These are default BT audio codecs that nearly every audio BT device can connect with. These are not high definition codecs where you won't hear the specific instruments in an orchestra and other audio. With that, they sound decent, loud enough for normal phone calls, listening to music, or listening to audiobooks or whatever you want to listen to. EQ Control The EQ function worked well. While you won't get amazing bass, you do notice it is there and provide nice sound. I've set my EQ to Rock and it sounds good. Phone Calls After making a few phone calls, no issues were evident. No one complained about being about to hear me speak. I could hear them without issue as well. Truefree App Interaction The Truefree app appeared to well with this set. Configuring the touch controls was easy and each touch function worked as you would expect. This is an improvement over some prior Truefree sets I've tested. With that, the touch pad on these is on the rear behind the ear. After getting used to the positioning, no issues with touch controls. My only suggestion is to instead have the touch controls on the inner ear section were the speaker is. Pressing the back of the set, pushing the earlobe moved the set and earlobe. It was fine, just felt uneasy if you aren't being careful. Moving the touch control to the inner part of the set would be more stable as the earlobe provides additional support. Battery Life First opening and using these earphones, they started at about 86% and whilst typing this on my phone and listening to DOOM (2016) OST, Rebel Galaxy OST, making phone calls, and now listening to Brothers of Metal, they are now at about 70% battery life. 15% in about an hour or so isn't too bad. Conclusion I'm a fan of this form factor. They are comfortable without being overbearing, weighing your ears down, and can remain for a long time without pain. They won't fall off if you're banging your head, running, working out, etc. An improvement of the app with the earphones makes this set a reliable and dependable set to choose. If you want audio without the pain of IEMs or the bulk of over-ear headphones, this is a solid choice. In addition to the above, the price is right. Currently, they are $40 on Amazon.

Compact design. Comfortable fit. Affordable price.
I am very impressed with these earbuds. I want to start off by saying I own more than a few styles of earbuds and Bluetooth headphones. Some expensive, most on the cheaper side ($30-$50 range). I spend a decent amount of time hiking and biking when the weather permits. I feel a lot more comfortable losing or breaking a $30 pair of earbuds as opposed to $100 or $200 pair. The B1s are the first clip style I have ever owned. I was looking for some that had decent sound and fit comfortably enough that I could wear with moderate exercise and movement for at least a couple of hours. The B1 earbuds exceed expectations in those areas. They fit very comfortably with moderate to heavy movement. I don't think I'd wear them playing football, but for trail riding, jogging, and hiking, the B1s stayed in position without being overly tight. Connectivity was a breeze. They paired immediately with my iPhone. No interference or loss of connection, I have had with the more affordable earbuds. I accidently dropped the case a day after receiving the earbuds with no damage. They exceed my expectations in terms of durability and functionality. The sound they produce is more than enough for my needs. I have seen reviews of similar products where people complain about sound quality of the earbud style. The B1s have great sound quality for an earbud style. They are loud enough to eliminate all ambient noise if I want to turn them up and they don't irritate my ears. I honestly think I could have these in my ears for a good chunk of the day without really noticing them. Battery life is also quite good. I have never run out of battery life (most of my uses are 1-3 hours high volume). The last thing I want to highlight with these is the case. With previous styles, I haven't really cared much about the case size. I changed my mind with these. The case is super compact! Just slightly bigger than my key fob. I could keep these in my pocket and forget about them. Very well designed product. The B1s will be my primary music source for a long time.

Maybe Good for You, Not So Much For Me
Fundamental issue I have: when I turn my head 35-40deg to the right, the back of the right earclip touches my head. The back of these earclips is where the touch sensor is. When I'm listening to music, this is no big deal (I like single-touch to be volume up/down, but you can choose this in the app), but when I'm on a call this hangs up, and I can't change that touch control in the app. I don't have this issue with the left earclip, and it's me not the earclips, I actually got a replacement for my first pair and the second pair acts exactly the same. Clearly from all of the positive reviews this isn't something that happens to most people. - Sound is reasonably good: a little dim with the Balanced (default) EQ, but with a custom EQ you can add a lot of V and get some decent sounding mid-bass and treble. Not a huge amount of detail, but it's not bad. The lowest frequency slider doesn't really do anything for these earclips, just no low-bass response. No fancy compensation for hearing response at low volumes, so at low volumes, these sound pretty dull; I listen at about 35-40% volume. - Touch response is good, you just have to get used to touching the back of the earclips, behind your ear. - Reasonably comfortable: I can wear these for a couple of hours with no issues, but I always feel them, I never forget they are there. - The app is quite good: a few preset EQs as well as an 8-band custom, an adaptive EQ that comes from a hearing test (that didn't seem to work right for me), complete customization of the touch controls for music, no customization for calls, and a Movie mode (which I assume reduces lag). - Calls were good, no issues with the other person hearing me clearly, but not much reduction of background noise. - Battery life was good: at about 40% volume, at an hour and 15 minutes I hit 83% on the batteries (on both earbuds, consistent battery life), so you should get 7 hours or so of battery life. For a lot of people, these will be a pretty good budget earclip, just not me.

Worked well for a few charge cycles, then completely stopped working.
Worked fairly well for voice-centric content like podcasts. I have a few other pairs so I’ve only used these a handful of times. After about 5 charge cycles, they are now completely dead and don’t respond to charging. The case doesn’t light up or anything. No physical damage or misuse, so it’s pretty disappointing for them to fail so soon. Nifty earbuds, but they don’t last.

Lightweight, crisp sound, customizable and responsive controls
I have been wearing them all day for over a week and find that they are light and easy to wear all day. I saw this design and wondered how these open-ear clip headphones would feel and sound. I am glad I did, because they are now my favorite open ear headphones. Left and right are marked on each earphone. When I put them on, it took a moment to find how they fit best and then I was very happy to find they are nearly imperceptible to wear. I don’t feel them at all. At the same time they sit securely on each ear! I have worn them while working out and had no problem with them moving at all. The sound quality is fantastic. Still, I could hear ambient noises, so wearing these while running water for dishes or vacuuming made them hard to hear. However, the volume has range! In a quiet setting, I am happy at 20- 30% and have room to spare if surrounding sounds are louder. I get a true 5.5 hours per charge and an easy 3 full charges from the case. The little oval case is about 2.5” long x 2” wide x 1” thick. It is like a rounded skipping stone that easily fits in the palm of the hand. The case recharges quickly using USB-C (a separate USB to USB-C cable comes with the case). I easily synced them with my phone, turned off phone Bluetooth and then quickly synced them with my computer. With Bluetooth on for both, the headphones work with whichever is playing sound. As with many headphones that pair to multiple devices, the one with sound takes over. If I turn off either device Bluetooth or “dual device connection” in the APP, then it will only connect to one at a time. I have just taken a phone call on the headphones and was told I sound very clear. They are IPX4 (meaning they resist water splashes from any direction but not immersion in water or from jets of water) making them suitable for everyday activities, plus workouts and bathing. Further, the app has a setting under More Functions called Drainage Function to blow out any moisture that may have made it into the earphones. In the APP (on my phone, installed, signed in, and paired to the B1 set), I navigated to settings and checked for any Firmware update for the headphones (there was not one). That took only a moment. Then I tried out the different preset equalizers (EQ) and even made a few of my own. There is a wide range for adjustment to sound preference. I also went to a very quiet room and performed the hearing test. This generated a personalized EQ to my terrible hearing (lots of tinnitus). After choosing an EQ, I checked the charge state on each headphone - which can be seen in the APP. Now, about the APP specifically: While the APP is not required for normal headphone use, it does allow updates to the firmware, seeing headphone specific charge state, and personalizing the EQ and touch settings, etc. FYI, when the APP is opened it creates a new instance for itself in Bluetooth settings (mine says “BT8932D”), close the APP and that goes away. The APP allows sending issues to tech support (under Help and Feedback, pressing the avatar at the upper left corner) and also performing Firmware updates (in settings found at the upper right corner), so any little issues that arise in the APP get addressed and the headphones get updates. Once signed in to the APP the first time, it does not need to be done again. Each time the APP is opened, I quickly “Accept” and “Connect Device”. I watched the video in Amazon Qs on how to get to the register screen.( I think after selecting accept, I clicked “forgot” at the bottom and that is where the register option was. Enter email, enter a “letter only” password, click to get a code sent to email. Enter the code in the minute allotted, view the terms again and click Register. Try again if it does nothing. It will work after a few tries.) The APP lets me see the charge level of each earphone. I find this useful when deciding if I should charge them and use a different pair when planning on doing some things. The APP offers many preset EQ to select from as well as offering a customizable and savable EQ option. This makes me VERY happy, and I have been refining my own custom settings to suit my hearing! Game mode and dual device connection and be turned on/off in the APP. There is also a place to customize the touch settings. I love that I can CUSTOMIZE and DISABLE ALL TOUCH CONTROLS here! I have long hair and, when wet, I accidentally stop, play, or turn sound up or down. Disabling touch on demand is the solution. There is also a hearing test to personalize the EQ. This is very cool as it tests hearing sensitivity across a spectrum of sound frequency types in about 2 minutes and used this to generate a personalized EQ setting. I would love to learn more about the tweaks made based on my weird hearing!

Very nice sound, feel, and look for the price
I really fell in love with my last pair of truefree earbuds because of how slim the case was and how comfortable they were without the silicone ear inserts most earbuds seem to have. I also strongly prefer to be able to hear my surroundings with earbuds in. These deliver all the same things in a very pretty package - they look like jewelry at first glance. I'm very impressed with how well they stay put, too; I think I'd have to take a few cuffs around the ears to knock them out. I never liked the over-ear hook style because I wear glasses, but these are super duper comfortable. The sound quality is about the same as my last pair of earbuds, although I do have to turn the volume up about 2-3 notches to be equivalent because these don't go quite as deep into the ear. That tradeoff makes them more comfortable for my small ears, though; even my last pair of earbuds, which were the most comfy I'd found so far, made my ears ache a little after 3-4 hours. These do not! Not big on having to install apps to use a device, so I'm glad the app is optional. I did install it and play around with it for a while though, and I love, love, love that I can remap the touch controls. Changed it to let me go to a previous song/lower volume with the left bud, and skip/increase volume with the right, just like my old ear buds. I do wish the charging port were on the side of the device rather than the backside, although that's probably being picky- my old earbuds just fit my charging dock better. Total nitpick. Still love my last pair too much to get rid of them, but they'll probably be my backup pair now. Given that they've lasted 3 years and the batteries are still holding a charge very well, I expect these ones will last a long time, too.

My new favorite ear buds
Prior to these earbuds I purchased a pair of Soundpeats Pearl Clip Pro earbuds that are similar style and thought I should compare these two to see which one I like better. SIMILARITIES -Bluetooth 5.4 -Dual Device Connection -Spatial Audio -Voice calls are decent as expected for this style earbud -Good secure fit - These stay on during workouts way better than traditional earbuds. -Touch controls - I honestly haven't gotten good at using either of them yet. MAIN DIFFERENCES -Driver: SP 12mm vs TF 10.8mm -IPX Rating: SP IPX5 vs TF IPX4 -Playback: SP 24hrs w/ 6hrs single vs TF 25hrs w/ 5.5hrs single -Weight: SP 5.85g vs TF 5g. -Price: SP is a bit more expensive than TF When comparing the specs you would think the Soundpeats are a much better option. While I like them and they were my first pair, I actually prefer the TrueFree B1. As you can see in the pictures the Soundpeats has a larger case and larger earbuds. Yes they have a bigger driver but bigger isn't always better. I think TrueFree bettered the sound of smaller drivers with their sound outlet design (they way its directed in the ear) and their reverse sound wave noise cancellation, the TrueFree sound a bit louder to me. Just from listening to each if I didn't know I would think the TrueFree has the larger drivers. Additionally, with the Soundpeat earbuds being larger and heavier I found the TrueFree to be more comfortable over longer periods of use. The TrueFree being smaller has a more streamlined look. Speaking of comfort when I got my first set I didn't like them and thought they were uncomfortable. I was almost going to return them however I gave them another go around and made some adjustments and they felt comfortable. If you buy a style like this, be sure to give them some time and make sure you have them inserted properly. I also found that if you tilted the Soundpeats up you would lose the sound. Lastly one little thoughtful touch that might get overlooked is TrueFree labeled each bud and the cradles in the case with a red R for right ear bud and white L for left earbud. While this is small touch, I find it useful. For me the winner is TrueFree B1

Ok, not so great
Updated Review: Sound Quality: Good when working, with clear audio and decent bass. Reliability: Initially had major issues (left/right earbud sync problems, frequent disconnections). The seller stood behind their product and sent a replacement set, which has been working for over two weeks. However, minor connectivity issues persist, occasional left/right earbud desync and inconsistent volume balance. Seller Support: Responsive and resolved the issue by replacing the defective unit, which deserves praise. However, they actively push for review updates (including WhatsApp messages), which feels intrusive. While their customer service is commendable, the pressure to modify feedback is unprofessional. Pros: Good sound, seller honors warranties. Cons: Occasional earbud disconnect issues, inconsistent volume, and aggressive follow-up for reviews. Would recommend cautiously, if the seller improves product consistency and respects buyer privacy, this could be a 4 star product.

free app - good looking when worn, good sound...affordable,
love them...get lots of compliments when wearing them and questions about the sound quality and they are one of the best clip ins I tried and I tried many..sound is good considering they are not in ear....and for a change the touch control almost works...(my fingers and talent for sensory touch buttons is not compatible so I usually struggle...but with these I sort of manage...the app is a bonus too..free of course..)

Disappointing
In general, they are nice and comfortable to wear. But unfortunately, after just a few months' use, the sound is much lower in one earbud than the other so they are impossible to use together :(

Comodos y Ligeros
hola, aqui les tengo mis puntos de vista despues de una semana de uso de este par de auriculares Truefree B1 los cuales vienen con varias cosas muy buenas y si sabes bien lo andas buscando y para que los usaras creo pueden ser una excelente opcion, pero vayamos por partes. primero que nada esta el punto del diseño, sere honesto, al inicio tuve mis dudas creyendo que no se escucharian bien y que serian incomodos, la verdad eso fue lo que inicialmente crei peeeroooo o sorpresa pues primero que nada son muy comodos tanto hasta el punto de en ocasiones creer o mejor dicho olvidar que los traes puestos, la verdad muy ligeros y muy comodos, ahora tomando en cuenta el sonido hay algunos matices que hay que ver inicialmente y eso precisamente va tomado de la mano con su diseño, veamos, estos auriculares no son de los que entran directamente al canal auditivo pero tampoco son de los que van tan alejados del oido como los de conduccion aerea pues al ponertelos quedan algo mas parecido a los tipicos auriculares de vastago que no llevan olivas de ningun tipo pero quedan muy cerca de la entrada del canal auditivo lo cual no cala en lo absoluto peeero por el tipo de diseño tampoco esperes un volumen digno de explotarte la cabeza ok, ahora bien suenan muy muy bien, las voces son claras y nitidas y bien presentes, los agudos son cristalinos y de buen nivel, los bajos aqui es donde estan los matices mencionados y los explicare asi, los sonidos graves estan presentes pero de forma algo discreta, si se escuchan si se notan pero mas que nada son los graves tipicos de golpe seco ya que los bajos de reverb son los que se pierden y creo yo es precisamente por el tipo de diseño que presentan pero aun asi estan y son de alguna u otra forma disfrutables. el diseño esta pensado en estos auriculares para dejar pasar algo del sonido ambiente pues son el tipo de audifonos para deportes ya sea ir al gym a correr o simplemente ir a dar una caminada o bicicleta pero sin desconectarte de lo que sucede a tu alrededor lo cual te permite estar consciente de situaciones que pudieran causarte algun problema, puedo decir que tienen el suficiente volumen para que el escucharlos aun en ambientes con algo de ruido no sea un problema y poder disfrutar de tus pistas de audio favoritas sin mayores problemas, al usarlos como manos libres suenan claros y con buen volumen al responder o hacer llamadas, la bateria es de una duracion bastante aceptable rondando el promedio de las 5 horas con un volumen aproximado del 70% y en general funcionan muy bien ademas de contar con el BT 5.4 que es el mas nuevo a este momento por lo que no debes tener problemas al momento de utilizarlos y emparejarlos con diferentes gatgets, adicionalmente cuentan con multipunto el cual funciona muy bien. el estuche es pequeño y se carga por tipo C brindando a los auriculares proteccion al momento de llevarlos guardados y recargar su bateria, algo que no he podido yo hacer es apagarlos teniendolos afuera del estuche lo cual se me hace un poco raro pero no es algo que entorpezca el uso, yo en lo particular lo uso mucho porque soy del tipo que no vuelve a cargar los auriculares una vez que los saco de su estuche sino hasta que me piden carga osea estando abajo del 10% de bateria pero pues aqui no lo he logrado hacer y forzosamente debo meterlos en su estuche el en cual quedan muy bien agarrados con pines magneticos y son facil de tomar y llevarlos a las orejas, vienen con sus logos de izquierda o derecha y embonan de forma correcta y facil, algo que me gusta mucho a mi en lo personal es que los auriculares no se conectan al dispositivo en cuanto abres la caja y eso a mi asi es como me gusta honestamente sino que lo hacen hasta que los sacas de su case y al momento de ponerlos en el case aunque no hayas cerrado la tapita en automatico se desconectan lo cual a mi en lo personal me agrada mucho. por ultimo vayamos a la aplicacion de Truefree la cual te permite no solo actualizar el firmware del producto sino que adicionalmente puedes con dicha aplicacion tambien personalizar el audio de los auriculares con diferentes matices, un ecualizados, y lo que para mi es lo mejor de todo es que puedes personalizar lo que deseas que hagan los gestos tactiles de cada auricular lo cual deberia ser un estandar para todos los audifonos BT la verdad, es una pasada, eso de poder poner que quieres que haga ya sea el auricular izquierdo o el derecho depende el numero de toques que des en el panel tactil ya se un toque, dos toques o tres toques asi como el dejar oprimido 1.5 segundos ya sea el izquierdo o el derecho la verda te habre un mundo de posibilidades para uno mismo personalizar al gusto real estos excelentes auriculares y por ende hacerlos aun mas funcionales a lo que necesitas de forma muy personal... un 100 ahi la verdad para la marca. creo es todo lo que puedo decir, si bien el panel tactil es inicialmente un poco "dificl" de usar es cosa de un par de dias en lo que te acostrumbras a el pues queda atras de tu oreja pero insisto es solo de acostumbrarte a ello. bueno eso es todo, gracias si llegaste hasta aqui y si tenias en tu mira estos auriculares Truefree B1 como opcion de compra pues espero que estos puntos vistos de mi parte te hayan ayudado a salir de dudas, que tengan un excelente dia y felices compras!!!

Excellent product
Very good sound when use within it's limits. There is some distortion when the music is too loud and complex. Very good sound effect. Excellent build quality. Had been using it while cycling and the hold is excellent and doesn't drop off. You can hardly feel them on your ears after a while. Highly recommended.
