Audio-Technica ATH-AL5NC Wireless Open-Back Headphones

Audio-Technica's ATH-AL5NC represents a rare hybrid: wireless noise-cancelling headphones that employ an open-back acoustic design rather than the sealed enclosures typically paired with active noise reduction. The 40mm drivers deliver frequency response from 5Hz to 42kHz, extending well beyond standard Bluetooth transmission limits when connected via the included 3.5mm cable. This dual-mode approach allows the open architecture to breathe naturally in wired passive mode, while digital ANC processing handles ambient rejection when operating wirelessly over Bluetooth 5.3 with aptX Adaptive codec support.

The aluminium housings reduce resonance while keeping total weight to 256g, and the earpads use memory foam with breathable fabric rather than synthetic leather to complement the open-back ventilation. Battery life reaches 24 hours with ANC active, extending to 28 hours when noise cancellation is disabled. Charge time sits at 3.5 hours via USB-C, with a 10-minute quick charge providing four hours of playback. The headphones fold flat for transport and include a hard-shell carry case, detachable cable with inline microphone, and USB-C charging lead in the package.
