Review on Plantronics BackBeat GO 2 Bluetooth Earbuds - White - Retail Packaging for Enhanced Wireless Stereo Experience by Jessie Vrbensky

I really like these headphones. Not bought for training, but for work. The first set I received (from another Revain seller) had a small defect in the left kidney. But this one works great. This headphone has the deepest bass of any headphone I have ever used. While some will say the earbuds get uncomfortable in the ear after a while, I haven't had any issues. They come with 3 different sizes of ear tips. The supplied standard worked great for me. It also fits well and blocks out any external noise very well. I confess I like listening to loud music and they don't seem to hit full volume, but they are very good. Battery life is about what they estimate - somewhere between 4 and 5 hours. However, I've found that I can use them until almost noon, plug them back in to charge while I'm having lunch, and come back and they're ready to go in the afternoon. The reality is that there aren't many situations where you want to listen to music for more than 5 hours at a time. The only thing that doesn't work is the pause button. And I don't think it's a device - I think it could be my phone. None of the pairs I used worked with the pause button. I need to pause my phone. But it doesn't matter. Range is really good. I can get up and go to many places in the office without taking my phone with me. I'd definitely say 30-40ft in range - sometimes more, but it's starting to break down a bit. In general, they are worth their money. Great headphone set!
