Frequently Asked Questions - Infrared Cordless HP12 BOSS

How do I pair the headphones with the transmitter?

The headphones automatically pair with the included infrared transmitter once both are powered on. Ensure the transmitter is plugged in and the headphone IR sensor has a clear line of sight to the transmitter.

What is the operating range of the infrared headphones?

The effective operating range is up to 10 meters in direct line of sight. Walls or obstructions can reduce the range significantly.

How do I charge the batteries?

The headphones come with rechargeable AAA Ni-MH batteries. Remove them and place them in an external charger (not included). Charging time is approximately 3 hours.

Can I use regular alkaline batteries instead of rechargeable?

Yes, you can use two standard AAA alkaline batteries. However, rechargeable batteries are recommended for cost savings and environmental reasons.

My headphones have no sound. What should I check?

First, ensure the transmitter is plugged in and powered on. Check that the headphones are turned on and the volume is not at zero. Also, verify that the IR sensor windows are clean and unobstructed.

How do I clean the headphones?

Use a soft, dry cloth to wipe the exterior. Do not use water, solvents, or abrasive cleaners. For the earpads, gently wipe with a slightly damp cloth and allow to air dry.

Can I use these headphones with a TV that doesn't have a headphone jack?

Yes, the transmitter typically includes RCA input. You can connect it to your TV's audio output (RCA or 3.5mm adapter). If your TV only has optical output, you may need an external DAC.

Are replacement earpads available?

Yes, replacement earpads can be purchased from Boss or authorized dealers. They are designed to be user-replaceable.

What should I do if the infrared signal is weak?

Ensure there are no obstacles between the transmitter and headphones. Position the transmitter at ear level and avoid bright sunlight or fluorescent lights, which can interfere with IR signals.

How do I store the headphones when not in use?

Fold the headphones and place them in a cool, dry place. Remove the batteries if storing for an extended period to prevent leakage.

Several BOSS AUDIO video monitors include a wireless infrared transmitter. The transmitter sends a high-quality stereo signal which can be received the HP12 wireless infrared headphones.

The infrared signal is emitted from the large dark lens on the front of the monitor console. Best sound will be obtained if you sit directly in front of the monitor within about six feet. If you choose to sit to one side of the monitor, you can expect good reception within 35° to the right or left of the monitor.
