Here's the thing about open-back headphones: the whole point is that they breathe. Audio-Technica is now betting wireless listeners will accept that trade-off at $279 with the ATH-AL5NC Open-Back Wireless Headphones, available today.
The specs are genuinely competitive. The ATH-AL5NC runs 53mm drivers and supports 24-bit/96kHz wireless audio over LDAC, plus AAC and SBC for the less demanding. Multipoint Bluetooth lets it stay connected to two devices simultaneously — laptop and phone, the classic work-from-home combo. Battery life is rated at 75 hours continuous, and a 15-minute charge buys another eight hours of playback.
The open-back design does what open-back designs do: air flows through the ear cups past the drivers, which Audio-Technica says reduces heat buildup and delivers a more natural sound presentation than closed-back cans. The company also claims 'minimal clamping pressure,' which matters a lot over a six-hour session. The CONNECT app adds EQ presets, codec switching, and discrete modes for low-latency gaming, noise reduction, and sound leakage reduction — software patches for a hardware choice.
That hardware choice has a real cost. The ATH-AL5NC will leak audio to everyone around you and cannot offer true noise cancellation. Those are not bugs Audio-Technica forgot to fix; they are the physics of the product category. The noise-reduction and leakage-reduction modes in the app are mitigations, not solutions.
For context, the HyperX Cloud Alpha Air sits at $150 — $129 less — though it is a closed-back design aimed at a different listener. The ATH-AL5NC ships with a 1.2m (3.9-foot) cable and a carrying pouch.
The demo is not the product, but the product is at least honest about what it is. Open-back wireless is a niche within a niche: audiophiles who want the soundstage of a planar-adjacent design without a cable tether, and who work somewhere quiet enough that leakage is not a social problem. For that specific buyer, 75 hours of LDAC playback at $279 is a reasonable ask. For everyone else, the changelog reads 'sound leaks out, noise leaks in' — and no firmware update will change that.
