Buy it if you want the best bang for your buck and you have a GSM Carrier! Conclusione,un buon prodotto con qualche piccolo difetto ma per il prezzo direi che ci sta tutto. My feet just werent totally flattering squeezed into the clear plastic, and I have a very narrow foot! Ill still use headphones with an amp for serious listening, but as far as earbuds/IEMs go Im sold. En general el teclado se siente, luce y suena genial a mi gusto personal. We had most of our major electronics plugged into this "surge" protector when we had a lightning strike. No one was hurt at our house; we used it on top of a flat bath mat. Easy to install, no rough edges, its exactly what we needed. they are not a Swiss knife of earbuds but they do a few things very very well. If the headphones are connected to my iPhone and my MacBook I sometimes have a little lag when watching YouTube.
