Specifications: Max. input power: 100mW Sensitivity: 97 dB/1mW; Impedance: 32 ohms Proper use of your headphones Using your headphones A note about electronic "bass boost": Many portable audio devices have a bass-boost feature which electronically alters the audio signal (particularly bass frequencies) sent to the headphone jack. These bass-boost features are designed to overcome certain limitations of conventional headphones. Your TriPortTM headphones have patented technology that delivers superior full-range sound without the need for any type of artificial electronic signal coloration. For the best audio performance, disable the bass boost on your portable audio device. Leaving bass boost on may result in exaggerated bass and potential distortion at loud volumes. Notice the markings L and R on the headband. These markings indicate the proper position (L for left ear, R for right) to ensure proper fit and performance. Put the headphones on and adjust them so the headband rests gently on your head and the ear cushions fit snugly (an effective seal) and comfortably around your ears (with your ears completely inside the cushions).

It is best to avoid extreme volume when using headphones, especially for extended periods. Do not use headphones when operating a motor vehicle or where the inability to hear outside sounds may present a danger to you or others. Sounds that you rely on as reminders or warnings may have an unfamiliar character when you are using headphones. Be aware of how these sounds may vary in character so you can recognize them as needed. Do not sit on or allow the headphones to be immersed in water.
