Pros: Comfy, nice low profile cord, quality build, Bass is good.
Cons: Too much coloration, lacking performance in mids and highs.
I honestly think you could spent your money elsewhere whether you like a flat response or want thumping bass. I can imagine if these need an headphone amp to truly show their colors but then again Bose should make this point clear on the packaging. I could not find the impedance listed nor the frequency response. Typical big brother attitude from Bose but they must have forgotten their are others now to give them a run for their money. Either way bad experience as I could not get satisfactory sound for the price. Most mid and upper frequencies sound muffled. Breaking in for over 15 hours did nothing.
