Headset JVC HA-NP40T True Wireless Stereo TWS Ear-hook Bluetooth Black, 20–20000 Hz, 10 m

JVC HA-NP40T is a True Wireless Stereo (TWS) ear-hook headset designed for comfortable, stable wear during daily use and active situations. The intraaural coupling and pivot motion hook secure the earbuds in place while the open-ear design keeps you aware of surroundings. Bluetooth wireless connectivity supports calls and music playback with a specified frequency response of 20–20,000 Hz and an effective wireless range up to 10 m.

Advantages

The lightweight construction and soft, flexible ear hooks reduce pressure on the ear for extended wear. An open-type earbud design permits ambient sound awareness while listening, and the pivot motion hook helps maintain the optimal listening position during movement. Sound is produced by 16 mm drivers with neodymium magnets for clear reproduction, and three selectable sound modes (Normal, High, Bass) let you adapt tonal balance to content or environment. Bluetooth 5.4 ensures a stable wireless connection, and a built-in microphone enables hands-free voice calls.

How to use

Place each earbud over the ear and adjust the pivot motion hook to secure the fit. Pair the headset with a Bluetooth-enabled device following the device pairing procedure; the headset auto on/off and auto connect functions simplify reconnection. Use the onboard controls to switch sound modes, answer or end calls, and activate the voice assistant. Charge the earbuds in the charging case and recharge the case as needed to maintain battery levels for extended playback.

Recommendations

For stable performance, keep the earbuds and charging contacts clean and dry. Use the Normal sound mode for balanced listening, High for clearer voice and midrange detail, and Bass mode when enhanced low-frequency response is preferred. Avoid submerging the headset in water; IPX4 splash resistance protects against light moisture but not full immersion.
