Review on Black FINIS Swim Coach Communication Device by Steve Atchley

UPDATED: As I purchased 2 sets of the Swim Coach Communicator, the second one had absolutely the same story. It worked well during the first training but started hissing loudly after it. The water has got inside the central part of the device, and it is dead now. This product is not waterproof, don't waste your money! What a shame to Finis.Initial review:I decided to buy it because of its very low price and decent brand. After the first 20 minutes of use in the pool, it just stopped working and reacting to any buttons. Also, I heard some hiss out of them. At home, I saw that the water has leaked inside because it was getting out. It is definitely not waterproof! I tried to charge the device but even more water started getting out after it heated.The quality of sound is OK to deliver the advice of the coach, it lacks bass sound compared to typical headphones. It could have been a good product but the IP waterproof rating is just a lie in this case. What a disappointment from such a brand.If you buy it you will regret it after the first use.
