You know you’re onto a winner when you’re mentally composing the review as you use something for the first time! Thanks to Lester’s review I took the plunge (sorry) and bought these earphonesI’ve never even tried swimming with music, I thought it would be too distracting. The endless pool however much I love it, is BORING!When Mayra Santos broke the world record for longest swim in an endless pool recently, my first thought wasn’t how much that would have challenged her physically to swim for over 31 hours, it was the mental challenge of keeping going when there’s nothing to see, only the tank in front and just plop, plop, plop. Herculean!So for me (and the other half) these headphones are great, I don’t have an Apple Watch, I just stick my iPhone on the side and it works anywhere as long as the wire stays mostly above the water.Adding snorkel in too and it’s exactly like a treadmill for swimmers. It’s perfect for endless pools. It would be nice to see how it works in a regular training pool, perhaps one day I’ll borrow an Apple Watch and put it through its paces.
