Lets review new in-ear headphones Skullcandy S2PGGY, manufacturer again does not tell anything about their technical details. Judging by their view, 8 or 10 mm drivers are built into them; information about their sound frequencies range, sensitivity, impedance, signal to noise ratio and maximal power input Skullcandy does not provide. Volume control module with microphone is built into their cable; price of device is 30 USD. Price of Skullcandy S2PGGY is not overly high, if they have very good specifications, but, accounting the fact, that manufacturer does not tell anything about them, it is better to buy high-quality in-ear headphones of Sony, Philips and other manufacturers with very good technical characteristics, which manufacturers openly name, and which has the same or even smaller price and quality design.
