Review on Premium SONY SP700N Truly Wireless Noise Canceling Sports Earphones - Black | International Version with Seller Warranty by Clay Ijaz

I really like these headphones. The biggest complaint most people have about them is the battery life. So far I've averaged 3-4 hours on a single charge. The case then offers two more full charges. I'm willing to bet that most people won't leave them in their ears for more than 3 hours at a time and will charge them once you put them in the case. They fit better than any other headphones I've used. The small part of the fin and the part that goes in the ear are comfortable and close-fitting. You can walk with it all day and have no problems. The sound does not match the headphones. Undoubtedly excellent bass. Another downside is that calling them isn't great either. They are alright. However, if you are in a noisy environment, it will be difficult to hear you.
