They are comfortable and durable. When I plug it in it just crashes the phone and forces it to restart. Bin begeistert, Erwartung sogar übertroffen. Over the years I have tried every sort or earplug to mask snoring noise. Had 2 separate pairs of these and they both have had the stitching in the sole fail in weeks. I have not worn it for extensive periods however, as I will be returning them pretty quickly. They also took a LONG time to arrive. Not even a moment of indecision by my phone about "what are these things?" (If youve every had a Bluetooth device that has only a weird set of numbers, letters, and colons to identify it, youll understand why this is so useful. and finding blue shoe polish proved impossible. The earbuds are very colorful and an incentive for 2nd graders to not lose them.
