The Pokka Pulps earpiece I used was kind of inferior that I could hear other things outside it. And today, it seems that its wire was kind of defective and loose that one of the sides would not get the sound so I bought the new Sony EX110AP/Li earpiece as an urge to continue my personal work on music arrangements as well as to keep on rhythm gaming on the arcades and mobile devices.
The bass seems to be impressive but the volume may be sometimes too loud compared to other previous earpieces I used. The earpiece also has the Smart Key app that is suited for the Xperia phones. Just a press of a button from the earpiece and you get some various controls like controlling the call or the playback.
