I love the quality of these headphones, however, the tech involved with connection is a nightmare. I've had the unit for two weeks and still cannot get them intigrated with any of my systems. The process with the phone versus plugging in the direct devise for blue tooth. If I would have been aware of the process I would never have purchased this set.
I've used the newly purchased headphones on several occasions and they are very comfortable and the sound is great. I impressed with the battery life. I've used the multiple times while exercising or walking and the still have a 80% charge.
The range is breathtaking, and the bass response took my breath away. The sound is as clear as the proverbial bell; while listening, I've noticed things in the mix that I never heard before! The Bluetooth connected easily to both my Windows laptop and my Kindle Fire.
I let a friend try them and, besides the sound quality, she remarked on how comfortable they are, and how completely they can shut out ambient noise. She's buying a pair!
