Swim with music

My only issue with the interval is it doesn’t last very long always seems after a couple a months it loses the connection. I think the wires should be thicker that connects to headphones

Thank god for music

It stays in place on my googles. I can’t swim 2,000 yards in a pool without music. Was easy to pair. Apple Watch holds well in place. I have already recommended it. You can listen to anything from your watch. Spotify, iTunes, audiobooks, downloads

So far so good, mostly

A very clever and innovative product. With some tinkering, listening to downloads offline on Pandora, etc. is pretty simple. Apple Music a bit more of a headache. Would give five stars except for two things: 1) None of the earpiece options seem to fit me well and, 2), the app that is intended to measure laps, time, etc., is balky and generally not accurate in my experience.

No success.

Not successful so far. I could not connect my apple watch thst has a grest deal of music supposedly downloaded from Apple Music onto it.
I am also worried about this device coming off from the goggle strap and sinking to the bottom of the pool.
