The Panasonic Shockwave RP-HS33 is a lightweight sport clip-on headphone. The Panasonic Shockwave RP-HS33 includes two models: RP-HS33-D and RP-HS33-G. The RP-HS33-D I orange, whereas the RP-HS33-G is green. Both models are lightweight, water-resistant, sweat-proof, and include an elastomer comfort-fit hinge for a more custom fit. In addition, the RP-HS33 (both models included) competes with the slightly more powerful RP-HS22. The RP-HS33 offers a smaller Neodymium magnet driver (14.8 mm versus 23 mm), a reduced impedance (16 ohms versus 24 ohms), and an extremely decreased maximum input power (50 mW versus 500 mW). The RP-HS33, however, supports a higher sensitivity (103dB versus 102dB). The Panasonic Shockwave RP-HS33 (both the RP-HS33-D and RP-HS33-G) is priced at $19.95, incidentally the same price as the RP-HS22.
