Quality: Fine, but feels cheap - keep them in the case or they will not last long.
Wireless: Bluetooth connection is hit or miss. Sometimes it connects no problem, other times its several minutes of playing around to get everything linked up. It works fine with the bluetooth link on my iPhone5. It took a while to troubleshoot sync with macbook.
They work fine now, I don't feel they are worth the money. I find they sound similar to the bose products - which is perfect for my needs. I find I reach for my inCase sonics more than these. I like to be able to just listen and not play around with sync, I like that my inCase are durable and I can just throw them in my pack and go, beats would not survive the rough treatment. I like the over the ear for comfort and noise control.
The wireless is not worth the hassle of the bluetooth connection time. On the ear is uncomfortable when studying all day. I would buy the inCase Sonics all day long. Go with comfort and durability. My two cents
I noticed that the band on this great headphone(wireless solo HD) is flimsy when I held it first time, but who cares as long as it sounds good and does what it is supposed to do right? But... mine snapped at where the metal part 1 1/2" from the folding hinge when I was removing it from my head. I was very careful handling this headphone knowing this engineering insufficiency.
It is not funny at all when you spent more than $300, and breaks this easy after less than 3months. I don't even want to think about if I ever dropped this head phone.
If money is nothing for you and willing to replace it as you do to $20 headphone, this is such a great headphone while it is working.
