Headphones — SVEN AP-B710MV

The AP-B710MV is a wireless over-ear headset from SVEN, the Finnish consumer electronics brand, built around active noise cancellation and long battery life. It is a closed design with a microphone for calls, a foldable frame, a soft headband and foam-filled ear cushions. SVEN offers it in two colours, black and grey, and positions it as a headset for music, films and calls on phones, tablets and computers.

Key specs that matter

A 40 mm dynamic driver sits in each of the two cups. The stated frequency range is 20 Hz to 20,000 Hz, sensitivity is 101 plus or minus 3 dB, and impedance is 32 ohm. The link runs on Bluetooth 5.4 with an operating range of up to 15 metres. A 500 mAh lithium polymer cell gives up to 90 hours of playback at 30 percent volume with noise cancellation switched off, and the battery charges over USB Type-C. The headset weighs 195 g and carries an IPx4 rating against splashes.

Engineering and use context

Active noise reduction relies on eight microphones, four in each earcup, with a microphone sensitivity of 42 plus or minus 3 dB. SVEN states that it identifies noise sources, follows changes in the acoustic surroundings and suppresses both low and high frequency interference, so it is meant for public transport, offices and travel. Buttons on the earcup change tracks and adjust volume. SVEN's Smartlife companion app, available on both Android and iOS, adds an equaliser, a choice of noise reduction modes, customisation of the touch controls and a charge monitor. Its Find Me function either plays a loud high-frequency signal from the headset or shows on a map the last place where it was used, which helps when the headset is lost. Besides charging, the USB Type-C socket can also carry a wired connection, which keeps the headset usable when the battery is empty. The folding frame makes it easier to carry in a bag, and in the box come the headset, one cable with USB Type-A and Type-C plugs, printed instructions and the warranty paperwork.

Pairing

The AP-B710MV links straight to a Bluetooth smartphone, tablet or notebook, and it has its own amplification and conversion, so no headphone amplifier or external DAC is needed. The 90 hour figure applies without noise cancellation, and running time will be shorter with it switched on. For calls on a computer, the headset microphone works over the same Bluetooth link.

Alternatives

The SVEN AP-B700MV is another wireless stereo headset from the brand, offered as a separate model in the same catalogue.
