Frequently Asked Questions - ATHDSR7BT AUDIO TECHNICA

How do I pair the headphone with my Bluetooth smartphone?

Turn on the headphone by sliding the power switch to ON. The headphone enters pairing mode. On your smartphone, enable Bluetooth and select ATH-DSR7BT from the list. If a code is requested, enter 0000. Once paired, a beep sounds.

How do I use NFC for pairing?

Ensure your smartphone is NFC-compatible and NFC is enabled. Turn on the headphone, then gently touch the area marked with the N logo on the headphone with your phone's NFC antenna. Maintain contact until pairing is confirmed by a beep.

How long does it take to fully charge the headphone?

The charging time is approximately 4 hours. Use only the supplied USB cable. During charging, the indicators show battery level: flashing red (less than 30%), flashing white (30-60%), then solid white (charging complete).

How do I check the battery level?

Press the touch controller twice quickly. The indicators light up briefly to show remaining charge: 3 indicators (60-100%), 2 indicators (30-60%), 1 indicator (less than 30%). Rapid flashing indicates low battery.

What should I do if the sound is cut off or distorted?

Lower the volume on the headphone and the connected device. Move the headphone away from interference sources (microwaves, routers). Remove obstacles between the headphone and the device. If the problem persists, disable the equalizer on your device or switch to another codec.

How do I clean the headphone?

Use a dry, soft cloth to wipe the surfaces. Never use alcohol, thinner, or solvents. Clean the ear pads and headband regularly with a dry cloth, especially after sports use.

Can I replace the ear pads?

Yes, the ear pads are consumables. Contact your Audio-Technica dealer to purchase replacement pads. Follow the provided instructions to replace them.

How do I activate aptX HD mode for better audio quality?

aptX HD mode is automatically activated if your device supports it. To switch to normal mode (without aptX HD), turn off the headphone and turn it back on while holding the volume control towards « - ». To return to aptX HD mode, do the same while holding the volume towards « + ». Check the codec via the indicators (white = aptX HD, blue = aptX, purple = AAC, etc.).

The headphone is unresponsive, how do I reset it?

Gently press the reset button on the headphone with a non-metallic object. This does not delete pairing settings. If the problem persists, contact customer service.

Can I use the headphone in wired mode via USB?

Yes, connect the supplied USB cable to the headphone and a computer. You can listen to music up to 96 kHz/24 bits. The headphone charges simultaneously. Note that the power button and touch controller are deactivated in this mode.
