These headphones are my first pair of Bluetooth ear buds. The ear pieces themselves are huge! You really need to adjust it correctly in order to keep it in. Then again, my ears are pretty tiny. I don't know about the other reviews that say the bass is rubbish, when it's amazing. It's not $200 headphones, were you would except the best bass, but the bass is excellent for the price. The fact that it's water resistant is even greater. The battery life is okay for me. I only listen to music about 1-3 hours a day, so it's perfect for me. Call quality isn't that great though. My friends had a hard time hearing me. Still, the best ear buds i have owned in general. I would recommend it. 

Question: How was the sound?
Answer: Call quality is n't that great though
