nthefaceTo be fair, BGVP has a record of poor QC w/ their previous IEMs. However, I think that's mostly because the DM6 got hyped to all hell, and they had to push out more units than they're comfortable with in a short span of time.
It's not an excuse for DM6 buyers who got defective units, but hey, I don't see anyone hyping the ZERO just yet.
yohopaI had some dm6's that lasted for 2 yrs taking to work and using at home. They did well considering i dropped them a few times and they got ripped off my head a few times also lol.
