lived up to expectations 3 minutes to install. so i went for the EC-2b, sold by Addice, Inc,; btw super fast shipping! Some, have a combination of Lows, Mids and Highs. *Updated after a month of use*First and most importantly, this ONLY plays music/podcasts from your PHONE (or audio playback device). This review is based on 60 days constant use of product. The sound is very good and they stay in my ears. Ultimately, the right earbud gave out after about three hours of routine use, hence the one star review. The only thing amazon would do is let me drive half an hour to drop them off at a Kohls for a return. I purchased these for the ear holders. Im pretty much already in love with this mousepad.
