Got the 1Q today. Sorry to say I'm disappointed. I wasn't enamored with the sound out fo the box, so, after a ton of tip-rolling, I decided to try a different cable and couldn't get the second (MMCX) cable or the orignal cable to connect with the right earpiece. Just won't connect. Never had that happen before. The connection on the left earpiece was iffy as well - it seems like it connects but there was no snap into place. Bummed! For what it's worth, the sound was okay. The extension was good end-to-end, there was good clarity and detail, attack & decay had a good feel to it, and the stereo image was fine. There was some serious harshness to my ears in the upper-mids & treble, though. Rock music at my normal (loud) listening level was not pleasant, but sounded decent at lower volumes.These are observations from 90 minutes of listening with no other burn in, so grain of salt.
