Grey TWS Earphones with 6-Hour Playtime

These true-wireless earphones come in grey and provide stereo Bluetooth audio for music and calls. The two buds pair with each other automatically, removing any manual step. A 40 mAh cell in each earpiece delivers up to six hours of listening, while the 400 mAh charging case extends total usage between wall charges.

Commuters wanting cable-free stereo.

The automatic pairing and compact case suit daily commuters and office workers who value quick, tangle-free connections. Buyers who need more than six hours of continuous playtime per charge should consider models with larger batteries. The 10 to 15 metre wireless range also limits use to nearby devices.

14 mm driver with 32 Ω impedance

A 14 mm dynamic driver rated at 32 Ω produces a frequency response of 25 Hz to 18 kHz with a sensitivity of 110 dB and signal-to-noise ratio of at least 90 dB. This specification determines loudness and tonal balance, letting buyers judge whether the sound signature matches their preference.
