H2O Audio Sonar IPX8 - Bluetooth Bone Conduction Headphones with MP3 Player - Wireless, Open Ear Waterproof Headset for Swimming, Underwater Activities, Sports, Workouts

HEY! It's incredible how much more comfortable i am than the overear openswim ones, i dont need to wear a cap and its amazing. Just a few things * You can use any goggles that have a silicion band (Most defaults) however its better if its in a Y shape towards the end (image attached 1) however youc an use any, can just be fussy (my speedo vanisher 2.0 is frustrating as it bungles up) - biofuse 2.0 is a good option to show how it would easily fit, as the vanisher has very thin sides and feels kinda bad to put on, but have never had it slip off once. There are folders you can put shit in, so usually i start with music to a podcast.

Does the job well. Good battery life and decent enough sound quality. People around you may be able to hear your music at full volume.

Lo uso para entrenar en alberca, y su sonido es espectacular. Es un tanto incómodo ya que va sujeto a la liga de los goggles, pero nada que interrumpa el entrenamiento.

This is a detailed review of the device. It is not a superficial critique of bone conduction technology. Some people prefer bone conduction, some don't. Inevitably, many negative reviews critique the bone conduction technology vs. standard speakers, rather than the devices themselves and their implementation of bone conduction technology. This is like buying a sports car and complaining that it doesn't get good gas mileage. I prefer bone conduction technology for my open lake swims and want the absolute best bone conduction headset specifically designed for swimming. I have tried them all, and the Sonar is at present the best available. I was a longtime Finis customer. I used their bone conduction SwiMP3. I kept 2, so I would have a backup in case 1 failed. Both failed within a week. They were older, but the rapid failure of the brand new (but older) backup device seemed curious. I could not get Finis to help me troubleshoot. The person at Finis I talked to was surly and argumentative. I did not expect warranty replacement of the Finis, it was old, but I paid more than $100 for it and wanted to understand the problem. I believe the problem was a short in the power cord that fried both devices. Finis does not sell replacement cords on Amazon and the cords were exorbitantly priced on their site. I didn't want to buy new cords at exorbitant prices for dead devices until I knew this was the problem. It again appears that a short in the power cord on the Finis fried both devices. The cord was pristine, not cut, damaged, frayed, etc. Bottom line, the entire process with Finis disgusted me and I will never buy another one of their products just on principle. The one glaring deficiency in the old Finis, besides abysmal battery life, was the lack of folder support. You must dump all the files into one directory and this makes it difficult to play different music selections at different times. The simple ability to create different folders and then move to another folder while swimming is a HUGE plus and I consider this feature mandatory in any swimming mp3 player I buy now. Finis does not have this folder support. It seems to be offering the same product from 5 or 10 years ago and resting on its laurels. The Sonar is smaller than the Finis and louder and clearer sounding. I have used both for hundreds of hours in the water. The battery on the Sonar lasts longer. The storage space is double the Finis. The Sonar has folder support, the Finis does not. The Sonar is quite simply superior to the Finis in every aspect, while having a retail price of $99.99 vs. $120 for the Finis, not that retail prices mean anything anymore. I never would have tried the Sonar if my Finis hadn't failed, so their shoddy products and awful support actually did me a favor. In the future, I'll pass on the garbage legacy Finis with half the memory, shorter battery life, a larger cumbersome size, no folder support, which will fail with NO support from the company. This is my honest opinion and no one paid or compensated me for it. I do long 1-3 hour open water swims and music is essential. Earpiece players are simply too much of a pain for me on long water swims, versus something I simply attach to my goggles, which stays put, and which provides steady and continuous sound even if I get pummeled by waves or wind. The actual resonator on the Sonar, the speaker for lack of a better term, is smaller than on the Finis. Because this is not a literal speaker, bigger is not necessarily better (not that it always is with speakers). So long as the device sits on the bone leading to the ear, the bone in front of your ear, it does not need to be huge to achieve the desired effect. Rather, I find that the smaller resonator on the Sonar produces louder volume than the Finis, perhaps because it can resonate more intensely with similar power at a smaller size. Regardless, I was pleasantly surprised to find that the sound of the smaller Sonar was louder and clearer than the Finis. The battery also lasts longer than the Finis, again perhaps because the smaller resonator takes less power to drive. Overall, if you know what bone conduction is, and want it, this is the best swimming player currently available. Given how much time I spend in the water swimming, having the best player possible is a pretty big deal. This is the best bone conduction player period. I actually dealt with tech support at the company to try and get additional charging cords and they were the exact opposite of Finis--friendly and helpful in other words. A better product, better support, Sonar wins hands down. I consider the bluetooth feature in all devices like this a waste of time and wish they would simply offer devices without it. Bluetooth doesn't penetrate water. Such features inevitably work sporadic at best, unless you have a phone or something right next to the pool. Some people doubtless love this feature, I could care less and I wish there were a way to turn it off permanently on my device. It does not impede simple, normal playback of songs loaded onto the device, however.

Bought it 7 month ago, used for 3 hours a week. Recently it started developing issues: no sound on the right side, turning off by itself from time to time.
