I checked to make sure they were open (yes, I tried calling at 1PM pst - 2PM pst) and nobody could be bothered to answer. Dafür habe ich diesen enttäuschenden Plastikbomber von Sennheiser hier gerne ausgemustert. My only concern that it remains securely clamped on bar as my last Garmin mount that came with the unit does not time will tell hence the 4 star review. Solid and durable construction. Jai retourné mon achat, malheureusement! I could wear these for a long time without major issue, only needing to periodically fidget with them, whereas the LS30, which is actually one of the more comfortable sets Ive tried, gets very uncomfortable and sometimes painful after an hour or two. I WOULD DEFINITELY SIZE DOWN A SIZE. However, I bought them to go with jeans, Ive only tried them on and am waiting for a dressy casual occasion to wear. A little flimsy. These have a stylish look to them and for me, fit in my ear comfortably.
