Verdict

The JVC HA-S20BT 'Flats' are ultra-lightweight (96g) on-ear wireless headphones featuring 30.7mm ferrite drivers with a 20Hz–20kHz frequency range and 30Ω impedance. These headphones utilize Bluetooth 4.1 for an 11-hour battery life (2.5-hour recharge) and include an integrated three-button remote with a microphone for calls and playback control. Their main pros are their compact flat-folding design, extreme portability, and an easy-to-use interface that appeals to style-conscious users on a budget. However, cons include a lack of a 3.5mm wired backup, no active noise cancellation, and a headband without padding that may become uncomfortable during long listening sessions.
