The only thing I would say is beware of the shoe sizing. Uno de ellos sirve para cambiar la ecualización, desconectarse de un dispositivo o hacer emparejamiento manual. Highly recommended, if you dont need wireless and dont want to pony up for elaborate "noise-cancelling" gear. I initially gave this product 5 stars. I rebought these cuz the last pair broke from abuse from me. YES, no need to return and get an inferior headset. l. Long term wise I?ll update how this works out, but I plan on buying this for people for Christmas. Its adorable but its not really as lightweight as I expected. The ONLY reason I am writing a review of this product, is because of the dual sided (or double sided) attachment for hard to reach sensitive skin areas.
