I cannot say enough good things about these wedges. These $79. A few years back I purchased a similar 3M item. 00 that they are selling for right now I might not have cared so much but I paid 94. I heard noises, and when I opened the cabinet doors, the bottles were down again. Pros:- sound quality exceeds expectation for $50- waterproof- little to no latencyCons:- the earbuds are a little bit large it was one of a kind. Auch ohne eine Einspielphase ist es nach einer gewissen Nutzungsdauer absolut normal, dass minimale Veränderungen im Klang des Kopfhörers bemerkbar sind. Didn’t even get a chance to rate the sound quality as they were too big to fit into my sons ear Look how UGLY this thing is.
