Pros: Bass, high quality, carry case, (comfort, isolation)
Cons: Mids, highs, comfort, isolation
Brought these way back in 2011 for what seems like a total rip off today of $80 or so.
Good: Bass, I think the bass is too dominant with these, it makes the mids sound bad and the highs are just absolute crap. Build quality is good, my right one's cable was not very securely attached to the stress relief but still held up no problem over the years. Stock tips didn't work the best for me, my ears and IEM's hate each other. I brought triple flange tips and the isolation is improved, as well as comfort and no changes to sound quality.
Bad: Stock tips not for me. Mids sometimes taken hostage by the bass. Highs were shot long before, they didn't stand a chance!
