It does not come in the full retail packaging with the cardboard card as pictured, just a plastic bag with the Sennheiser sticker on it. The battery I charge every 2 weeks and I use it 2 times a week on my face and neck The cut out arms I love! Sound quality in wireless mode vs wired can be massively different, especially when it comes to instrumental music (and especially string based instruments). A constant connection between the phone app and the tile is infeasible to maintain over the course of a year on a single battery. Its international, but all connections are north american.

Unfortunately, these ear pads have a tendency of becoming loose and slipping off, since the hooks to secure each ear pad on the headphone themselves arent tight so the ear pads arent secure. Da der Libratone preislich fast gleich liegt, kleiner und leichter ist, das besser ANC hat und vor allem linearer und detailreicher klingt, habe ich mich für den Q Adapt OnEar entschieden. Overall, these shoes are awesome and well definitely order more
