The sound quality is very good the range is excellent. Non hanno il bluetooth, non possono essere connesse allo smarthphone e non possono essere cablate. Mais alors . The USB ports were also a great addition, letting my wife and I keep our phones and Kindles charged for the duration of the trip. Closetmaid will send replacements, but be prepared to wait. So if you are opposed to washing your face in the shower I would think twice about getting this one. I should have returned them sooner. I did try them all -- as well as some aftermarket Comfy foam tips -- none of which adequately sealed my ear canal. The table itself is sturdy if installed properly. I can wear it for trips to the store or gas station.
