TechnicsReference Class Hi-Fi Wireless Earbuds, Dolby Atmos, Head Tracking, Adaptive Noise Cancelling, 3 Device Multipoint, 10-hr Battery, Wireless Charging, in Ear Headphones - EAH-AZ100-K (Black)

Amazing sound! Best I've ever heard from a set of earbuds. I moved up from a cheap pair with no ANC, and the difference in quality is immensely noticeable.I spent WEEKS mulling over which brand and model to buy. I'm a casual audiophile, so I wanted incredible sound while also factoring in comfort, features, battery life, and user reviews.I narrowed down my options to this and the B&W Pi8, which I knew would also be a good choice. The reason I chose this over the Pi8 is use reviews. Nobody complains about the sound quality of the Pi8, but the overall user experience for the AZ100 was higher, so that swayed my decision.Let me tell you, brother, I am more than happy with my choice! Here is what I love about this product:Sound quality: Listening to Ultra HD music with LDAC enabled is a religious experience. I'm listening to some music I've heard a LOT before, but it's an all-new experience for me. It's like falling madly in love with the same person all over again! I prefer stereo mode, but using positional audio with Dolby Atmos and head tracking is a nice option, and I've found it to be really great on certain tracks, especially those specifically designed with 360 audio in mind.Comfort: My old, cheap earbuds were pretty good, for the price, but I had to fiddle with them a lot to get to stay in and feel okay. Once you go through the guide to figure out what size tips to use, these earbuds "lock in" better and feel great. It's like I forget they are even there. The longest I've ever used them so far is two hours straight, and I felt zero discomfort.Noise cancelling: Impressive! I've never experienced ANC before, so I cannot compare it to Sony or other brands, but this is a game-changer for me. I live in a very quiet house in an extremely quiet neighborhood in the middle of nowhere, and I thought ANC would be overkill at home, but I was wrong. It's crazy how much ambient noise there is that you don't even think about. When I turned ANC on at home, I think I audibly gasped! I had never "heard" so much silence before! 😂When I started listening to music, it was something special, and I knew I had made the right choice to spend good money on a premium product.Customization: The app lets you adjust equalizer settings to your liking, which is a must for me. I know this is standard for premium earbuds, but my last one only had presets, and no matter what I did, the bass was always too much, even with the "Bass reducer" setting. I don't understand the appeal of the power frequencies overpowering everything... but I digress.Beyond the equalizer adjustment, you also have so much control over the noise cancelling settings. When I'm at work, I can not only turn off ANC altogether, but I can adjust how much of the outside world is boosted. I have to be attentive to my coworkers and notifications on my computer, so it's amazing to be able to hear everything so clearly and still be able to hear the music in such amazing detail.I cannot say anything negative about this. $300 is a lot to spend on earbuds, so that may be one aspect of this that some would find as a negative, but this is probably the last set of earbuds I'll buy for a VERY long time, so that's one way I justify the price. The other is that you really get what you pay for here. Multiple professional reviewers list this as the best overall option for 2025, and they have done that with good reason. If you are on the fence like I was, and you can afford the premium price tag, I think you'll be beyond satisfied with your purchase.

I’m giving these 5 stars, as the sound is incredible, the battery life is top notch (I’m probably past 6 hours since my last charge and the case is still at 50%), and the case is super small and light. I can see why people might complain about the noise cancelling since it isn’t perfect, but I prefer to hear slight background noise and not be completely deaf to the outside world (that’s insane in my opinion). But I can still use my lawnmower or chainsaw with no pain to my ears. They connect seamlessly as soon as they hit my ear.Small cons: while they don’t bother my ears, I can see why people might have an issue with them after extended use. I also hate that they aren’t MagSafe compatible, that drives me crazy.Overall great product and worth the money.

I am an audiophile and music is important to me. I was always warned against going wireless. I was extremely surprised by these IEMs! The sound quality is great for the price. It is not only how good the music sounds, it is how well it isolates you from the train and subway noise. The ANC is excellent and they fit tight enough to offer some decent physical isolation. Several different silicone tips are supplied to allow a proper fit. The experience of wireless is an extra boon. I had no problems with connectivity, and I didn't get any noise or disconnections that I sometimes had while walking with my wired IEMs. It also gives good phone functionality to call and answer calls and allows me to control the music while my phone is in my pocket. The battery has been great for me so far. The black IEMs look good, almost dignified. Of course, I have equipment that sounds better than these, but they cost more and are far less suited for the commute. I highly recommend these IEMs!

These earbuds are SOOO close to being perfect it drives me crazy. I'm coming from the AZ-80s and most of the features are improved (but not all). Depending on your needs, my issues may or may not be relevant to you so let me break it down for you:Things I Love1) Transparent Mode & External Mics - these things are AMAZING! They work so good! I was especially impressed when I used them at a concert recently. The measure sound volume at the concert was 100-106db. I poped in the earbuds and set the mode to 14% transparent. The sound was GREAT and the volume level perfect. I tried the same with the AZ-80 but loud environments would override those mics. Not with these. The only time I've had a the external mic flake out is when I was weed-whacking and the string hit some metal siding. Honestly - super impressive!2) Sound Quality - I have very high standards when it comes to quality SQL. I've used these with many devices including an iBasso DX170 in LDAC mode and my phone. The sound detail is amazing. Hearing things in the music I dont typically hear with a pair of earbuds. Yes, the SQ is really that much better than the AZ-80.3) Phone Call Quality - Again, compared with the AZ-80, these are WAY better. I regularly take calls in my car and half of the year my convertible top is down. I've been able to have 20min plus conversations at highway speeds with the top down with the other party saying they could barely hear the road noise at all. Well done!Mixed Feelings1) Size and Shape - while I appreciate the smaller size of the AZ100 earbuds compared to the AZ80, they are a little more difficult to grab. They are more rounded and you have to be a little more intentional about getting a firm grip on them. Once they're in your ears, its a better more streamlined fit but you need to be a little slower and more careful moving them around.2) Noise Cancellation - when wearing them around home or out on a walk, noise cancellation works great. They seems to have some issues though maintaining the noise cancellation mode on airplanes. I've had the pleasure of testing them on a number of different flights recently and while everything starts off well, after 20-40 mins or so the noise cancelling will start to whoosh out and then back in. It might be something about the white noise of the airplane engines. To fix it, you have to open the app, turn noise cancelling off then back on. I've had this happen more than 25 times on a one hour flight.2) Battery Life - my fist set of earbuds had a battery drain issue. The left earbud would drain the entire pack just when sitting in the case not being used. Left me with a dead set within less than 24 hours of storage. The set was replaced under warranty and the 2nd set is working as advertised. The warranty process was a little bumpy - more on that below.3) Warranty - unfortunately I had the opportunity to try out the manufacturer warranty process due to a batter drain issue. Contacting and communicating with support was pretty good - they were responsive and helpful. The only challenge was that the replacement set came back to me in Silver when I returned a set of Black earbuds. When I inquired as to the incorrect color and how I could be sent the same color that had failed, I was pretty much told - too bad. You get what you get. Kind of sucks considering I ordered the color I wanted, they failed in less than 2 months and how I have a functional set ... except for the weird color. A small detail I know but it would have been better if support had notified my first rather than surprising me and then denying my request for the right color. I hope you mileage will vary.Things I Don't Love1) App Responsiveness & Reliability - in general the App works well once its open and successfully connected. Unfortunately I've had way too many times where the app cannot find the earbuds even when I'm playing music through them and Bluetooth shows connected. I just kill the App and restart but its really flaky. Even the initial load and connection of the app takes annoying longer than I'd like - especially when I'm only trying to change the transparency level or some other basic setting.2) Touch Responsiveness - switching the earbuds on/off when I'm at home or in a setting where I need to hear a PA announcement (ie. airport) seems to take a little while to register. I know I'm being a little picky but earbuds block you out of the world around you. It should be quick and easy to return your focus to the world around you as needed. Just takes a but longer to register the press and mute the earbuds than is helpful. Many times the announcement was over or I would have missed most of the question by the time I got the earbuds muted. Could be quicker/easier.
