H2O AudioInterval Swim Headphones for Apple Watch – Waterproof IPX8 Swimming Earbuds with Bluetooth, 6-Hour Battery Life, Open-Ear Bone Conduction, and Goggle Loops – Blue

I purchased the H2O Interval to replace a 'HIFI Sound Waterproof MP3 player for swimming' that you can also find on Amazon. I wanted the convenience of playing music from Apple Music/Spotify/Amazon Music/Podcasts, without having to buy and download them onto the device.The design of the device is great: it's sturdy where it fits against your head and holds the Apple Watch face and the bone conduction pads are compact and comfortable against your head. The bar that holds the watch in place is rubberised to accommodate different sizes of Apple Watch faces. The volume/skip track controls are easy to find in the water and essential as Apple Watch faces do not work when in water and neither does Siri (unless your phone is nearby or you have the cellular version).I spent ages researching different options and ultimately settled on this because of the Apple Watch integration.Things to bear in mind before buying the H2O Interval:- The device is limited to swimming only as the bone conduction pads and holder for the Apple Watch face attach to goggles.- The device does nothing without an Apple Watch attached. Your watch is the source of music/podcasts.- Apple Watches are designed to get wet but can get water damaged so there is always that risk to consider.- Your Apple Watch cannot track heart rate and other vitals whilst swimming as it is not attached to your wrist. H2O do have their own swim-tracking app though for length counting and goals.- Make sure you've downloaded music/podcasts to your watch in the Watch app on your iPhone. These sync and update automatically so you do not need to always do this.

It works really well - sound can be slightly better with earplugs. However I realized a bit too late that a system with a smartphone near the pool and bone conduction with blue tooth could help you save the purchae of the apple watch ( you can also use the watch to measure performance on your wrist though)
