Query: Backphone with Bass

In wearing these backphones, make sure that bracket connecting the earbuds passes between your upper ear and your head. I personally find that wearing this unit for an extended period of time can become uncomfortable. Ladies, this unit may interfere with your hairstyle.The sound quality is quite acceptable, below are the specifications for this unit:- Driver: 10mm Cobalt Magnet- Frequency Response: 20-20,000 Hz- Impedance: 16 ohms +/- 10% at 1kHz- Cord Length: 4 ft.- Max. Power Input: 60mW- Sensitivity:103 +/- 3dB at 1KHz- Plug type: L-shaped Gold Mini 3.5mmIn conclusion, this is a reliable headset that sounds great, however, wearing it can be the issue that will govern its usability.
