The Panasonic Shockwave RP-HS22 is a clip-on portable headphone. The Panasonic Shockwave RP-HS22 includes two models: RP-HS22-D and RP-HS22-W. The RP-HS22-D is black and orange, whereas the RP-HS22-W is white. Both models are water-resistant, sweat-proof, and include washable pads and 1 additional pair of cups. In addition, the RP-HS22 (both models included) is an upgrade from the RP-HS11. They feature more power (500 mW versus 250 mW), a larger Neodymium rare-magnet driver (23 mm versus 19 mm), increase sensitivity (102dB versus 95dB), and a superior impedance (24 ohms versus 16 ohms). The Panasonic Shockwave RP-HS22 (both the RP-HS22-D and RP-HS22-W) are priced at $19.95, a $7 increase from the slightly weaker RP-HS11.
