great sound; punchy, well rounded sound

Excellent. Exactly what I needed for when I go to the gym. Very loud and comfortable with the different size earpieces they come with. Would definitely recommend!

The sound quality is awesome. Setting up is extremely easy. The battery life is decent.

There are so many wireless earphones out there that it's hard to keep up. JBL has a few different models, and they've been quite successful in the sports and "value for money" markets. I'm about to test their T100BT model, which is in the cheaper price range.
