Bought a pair of Etymotic ER2XR's. Not 6 months in the left channel volume dipped quite drastically. Chatted with a tech, sent him the RMA and receipt, they sent back an authorization form. I shipped back the faulty unit and they claim they will send out a new one this week. Wow. That easy? Anyone else have a nice Etymotic IEM warranty repair experience. So far I'm impressed. They sound very good by the way. Learned about them on ASR and have been very impressed. Amazon has them for $80 now. I bit at $100 and right after price went up to $150.
