H2O Audio Sonar PRO IPX8 Waterproof Bone Conduction Headphones – Open-Ear MP3 Player with Playlist+ App for Bluetooth Streaming & Custom Playlists – 7hrs Battery for Swimming, Sports.

Delights / Pro's:**sound quality and volume is amazingly good. Be sure to record music at full volume. Then you can turn down to your preference.**size is comfortable. I have a smaller head and smaller ears. Fits just fine. The cord that connects the ear pieces is longer than I need, but given it's one-size-fits-all, it's not a deal breaker.**Fits over pro-swimming googles. My goggles have a thicker strap to them than the average google. The thicker strap still fits into the strap slot just fine.** I swim about 45 minutes a day. The battery lasts me about two weeks of swim sessions. Charging is very easy (do NOT lose that cable!), so it's no big deal to charge.CHALLENGES / Con's** Designed only for swimming. BUT I've worked around that. I found thin headbands on Amazon and I use that if I want to use these when riding my bike. When out of the pool I don't want to use in-ear phones so I can hear traffic etc around me. The head band is perfect when riding a bike. I have not ran with them ... I don't run.TIPS** keep the instructions on how to load songs. If you want to be able to "one tap" change to the next song, then you MUST record each song individually. Personally, I'm not going to do that. So I created short play lists of 1 hour. Then I can skip a play list if I'm not feeling it.** loading songs instructions give an outline but I had to figure out individual steps for loading with my paid spotify account and Android based phone. Attached in a picture which might save you some anguish. Hope it's helpful.WISH LIST** Manufacture would make a deal with Spotify for automatic pairing and song upload. As a swimmer, I could pair the h2o audio with my spotify account, then select playlists, albums, podcast, etc to download directly. The leave spotify playing to record is cumbersome.

I have used bone conduction swim headphones for years. I have used Finis brand for over 6 years for swim workouts. I decided to try this brand after i found the Finis were out of stock. Big mistake. These are terrible for swimming laps. The sound quality is terrible compared to the Finis brand. These just sound like a cheap rip off on bone conduction tech which is amazing when it works properly. I found the Finis brand on another website so i am going back to those. The only good thing about these, they clip onto your goggle strap which is a must for flip turns. The Finis brand clip on as well.

Works well while swimming laps - 25 yard pool. Easy instructions, Arrived fully charged. Connectivity was pretty easy to setup with my iPhone. Comfort - light and stay secure on my goggles. Buttons are easy to feel and press while swimming to change songs or control volume.

I purchased Sonar pro after buying at least 5 other music underwater readers. I swim for an hour every day and you know swimming in the pool needs some motivation to make you stay in the pool back and forth for an hour. Sonar Pro made my miracle: I was tired of just listening to music, with my Sonar Pro I can easily listen to audiobooks and podcasts with a simple click without having to transform the files to load them on the player. Double click and you come back after a while and everything is on your Sonar, easy and immediate. I had some doubts about the voice quality because I had tried other products and the voice speech quality was insufficient, but with Sonar pro even whispers can be heard well while you are swimming. And I no longer have problems with Blue tooth connection loss because everything is on the memory and organized on the playlist!! But in addition to the excellent product, what makes the difference with this object and competitors is that the support received during the after-sales service was incredible: I always received an answer to every doubt or question within a few hours, in a friendly and supporting manner. Other products leave you alone after the sale, which often makes you regret having purchased that product. Congratulations again for your product and for making swimming always fun!! Highly recommended!!

I use a 1/2 inch tie to keep it on my head…have not used yet so don’t know if that will work or if they work as advertised. This is my 3rd brand of swimming ear music devices. Different brands…if this one does not work I give up.

These headphones were the answer to boring lap swims. The sound quality is excellent, the buttons are large enough to use by touch so you don't have to remove your goggles to adjust the volume. I like everything about this product except for the music downloading app. It is pure 1990s tech that records as you are playing. Playlists are restricted by time, usually 20 minute increments or 30 minutes to hours. It requires time & forethought to actually get your work out music ready & if wifi drops or you get a text/call, the music is interrupted. I really expected a better way to add music at this price point.

I am swimming the long sessions like 3+ hours and doesn't mater how you like to swim to shuttle in 25 meters pool become little bit boring. I have a few bone conductive MP3 players and all of them required a process of downloading MP3 files from computer library. With H2O I am able to download from my streaming music provider and Youtube this is really fun. It is also very user friendly. The best what I have

What a disappointment. Horrible. Negative star.The first one that I bought was excellent/perfect, and I loved it for years.Then I lost it, bought another one, and it wouldn't work like as before.I followed their directions and converted my music to MP3, but it stillwouldn't download to MEMORY.Bluetooth would play the music, but not when I swam freestyle or breast stroke.Again, this is my second H2O sonar; the first was great.Amazon's help didn't help, and I want my money back. Or, send me an older version. LSW
