I want to say that the Image-One BT's I bought from Woot on the January deal must've been the one bad build or something. In comparison to the wired version I bought direct from Klipsch: the sound was muffled and poor quality, the earpads felt very uncomfortable, and it overall felt like a used product. On top of this, the buttons on the side of the earcup often didn't respond on the two pushes, and the BT pairing required that I kick out all other pairings I had set up on my phone.
Woot was very kind to set me up with a refund because they were out of stock--although funny thing is they had another deal for same headphones and price a few days later...
Rather than getting my money back, I thought to first contact Klipsch and ask if they could help me out with a replacement.
Long story short, I received my replacement last night and it is VERY different: definitely has a new-product feel to it, sound quality is distinctively better, and I can actually wear them for as long as the wired version.
Loving the BT version. Again, benefit of the doubt: I think I just got unlucky with a bad one.
