Since my legs and knees have been bothering me, I have taken to swimming laps in a 25 meter pool daily. My friend Carl Trop touted me onto underwater headphones with 8GB memory. FINIS DUO is the product. I load it up with MP3 files, charge it, attach the phones to my goggles and the phones rest on my cheekbones. The sound is conveyed through the cheeks and is amazing underwater. Today I swam 20 laps, (a kilometer) listening to Horowitz playing Scarlatti and Pollini playing Shubert. The laps flew by. Frankly, I still can’t believe I can even swim that far.
