I am a very proud owner of the UE9000 since the very first day it came out, I also have many other pairs of what here headfiers like to call high end. For years I been waiting for any company to come up with a solution for high quality wireless portable sound that also looks good. My very first in-ear was an ultimate Ears superfi eb 11yrs ago, I also used a few Logitech products, gaming keyboard, mouse and speakers etc. Since then I always hated cables. While all other headphone companies were concentrating on high quality headphones with cables, Logitech had some bluetooth ones that had a small dongle that plugged straight into the 2nd gen ipods and it sounded terrible. That was more that 10 yrs ago. Logitech though concentrated on bluetooth technology, they came up with a few different devices and favorite one was the Squeeze box. The sound from the squeeze box in terms of how bluetooth can be limited was proved wrong. They nailed it perfectly. I always knew that Logitech had did their homework and has mastered how to use bluetooth at their best. Partnering with Ultimate Ears was a marriage made in heaven. For me the UE9000 and a Galaxy S3 Jellybam rom, it the icing on the wedding cake. After 2 months of burning in, yes, burning in does matter. Burning in is confirmed, and it just gets better. The bass gets deeper and rounder, no distortion that was there at first, the bass was a little bit too much when I first got it, now it's been tamed. I love these. I am keeping those, until something better comes along.
