NANKRunner Diver2 Pro Bone Conduction Headphones, IP69 Waterproof Swimming Headphones, Wireless Bluetooth 5.4 Open Ear Headphone with Built-in Mic, 32GB Bone Conduction Earbuds for Cycling Sports

Hi Guys: I have now had this set of waterproof Headphones for a couple of weeks. I work out with them at least five or six times a week for a couple of hours both walking and swimming. So far I like them and have only really have a small complaint. I like the way they work and and generally pleased with them. When you first open the box you will need to charge them completely. The charge cord comes with them. The right side headphone has three small buttons. (Look closely, you will see the buttons. I have to put on my reading glasses, but you can see them.) To turn them on you need to gently hold the middle button for about 3 or 4 seconds. The headphones will vibrate shortly and you will hear "bluetooth mode" At this point you can open your bluetooth device and find them and pair them. I use my apple watch and pair with my watch for my walking. You can control your volume with the two outside buttons on your headsets fairly easily. Remember these are bone conduction so you don't have to put them into your ears. Just put them on your skull right outside your ears. I can hear fine when I am walking. When I am done walking and getting ready for my swim I put them into MP3 mode. All you have to do to move from bluetooth to MP3 is press the same middle button that you used to turn them on three times very quickly. Once again it will vibrate and you will hear TF mode. That is MP3 mode. (Bluetooth doesn't work in the water if you headphones are submerged for any length of time..) With the MP3 mode on I enjoy listening to music while I am doing my swim. In fact in the water the sound comes through louder and I sometimes have to tun the volume down a little. The unit comes with ear covers that fit inside of your ears to cut down on water noise, but I don't use them and still don't have any trouble hearing my music. If you are just outdoors and fishing or playing in the water you can probably just leave the bluetooth on. But I swim to work out in a pool and if you are doing that you are going to need to go into MP3 mode. You do have to download music to the memory of the MP3 player on your own. They have three songs downloaded to the MP3 player, but you are going to want to download a few more songs I think. If you can't figure out how to do this please just send me a note and I'll be glad to help you out if I can. The minor problem that I have been having is that I use these for cordless headphones at home when I am on my laptop. I seem to have a problem with the headphones disconnecting and re-connecting to my laptop once in a while. Sometimes they shut off when they disconnect, but most of the time they reconnect almost right away. I am not moving around in the house when this occurs, I am just sitting at my computer and not moving when this happens.

Been using these for about 4 months now and they haven't disappointed. Very fast charging, they've lasted me a good while on one charge (have had to go maybe 2 weeks without fully charging and still only went down to 20%), and the audio quality is good without the noise cancelling mode, and so much better with it.Amazing underwater quality, it's such an ethereal experience, and putting music into the device is easy too. Volume's fine either way, underwater or not.Customer service was great too—make sure to activate the warranty. I reached out when mine began to malfunction for one reason or another, with the Bluetooth, and they sent me a fully new headset within 5 days. 10/10, would definitely recommend this bone conduction headset.

Fantastic for Swimmers and Athletes!These NANK Runner Diver2 Pro Bone Conduction Headphones are a game-changer! The IP69 waterproofing is no joke – perfect for swimming laps. Sound quality is surprisingly good, and the open-ear design is super comfortable for all-day wear during cycling or other sports. Plus, 32GB built-in storage means I can leave my phone behind. Highly recommend for active individuals!

I've swam about 50 miles with these between JAN to MAY 2025. Great battery life and there is no need to use the underwater mode, it does make the music sound worse if you turn that feature on.I would buy these again.

These would have a 4 star if bluetooth didn't loose signal in a few inches of water. I use these swimming, and they do work, but if your using bluetooth every time my ears go a little under water the signal is lost. I have not used these as a mp3 player yet. The sound quality is good. I have not used for more than 2 hrs at a time. They have gone in pool at least 100 times so far.

works well indoors but it is not biking weather and need to use it for the MP3 function in summer

I tried these for my swimming every day and they are pretty convenient really good. I really like it because they’re waterproof so I can hear music at the same time. I really recommend.

The Bluetooth was horrible on them and the battery would not charge. I put them on the charger and the headphones got extremely hot and the indicator light never turned on. Took them off the charger and they no longer work. Had them for less than two days. Tried to message the seller for a replacement, and they never responded.
