Audio-Technica ATH-AL5NC – Open Listening Without Cables

Audio-Technica Ltd. is taking its open-back headphone range in an unfamiliar direction. The ATH-AL5NC retains the acoustic principle associated with the company’s R-Series and ADX-Series models, but removes the restriction of an exclusively wired connection. Bluetooth, up to 75 hours of battery life and app-controlled functions bring the concept much closer to contemporary everyday listening.

That changes where and how an open-back headphone can be used. Music at a desk, long working sessions, gaming and video playback no longer require the listener to remain physically tethered to the source. The open construction still means that external sounds remain audible and music can escape into the room, however. This is not a closed wireless headphone wearing an open-back badge, but a product built around the advantages and compromises of the principle itself.

An Open-Back Headphone Set Free

The defining feature of the ATH-AL5NC is not Bluetooth alone, but the combination of wireless operation and an open acoustic design. Most wireless over-ear headphones use closed earcups to isolate the listener and limit the amount of sound reaching the outside world. An open-back model takes the opposite approach, allowing air to move behind the drivers and reducing the acoustic separation between the ear and the surrounding room.

This principle is commonly associated with a more expansive and less confined presentation. It also brings unavoidable limitations: an open headphone provides considerably less isolation, while those nearby may hear some of the music being played.

Audio-Technica therefore positions the ATH-AL5NC primarily for listening at home. It is intended for people who want the freedom to move around while listening, working or playing games, but who deliberately prefer the character and wearing comfort of an open-back headphone. A conventional closed model remains the more obvious option for public transport, flights and consistently noisy surroundings.

Large Drivers Behind the Open Earcups

At the heart of the ATH-AL5NC are dynamic 53 mm drivers developed specifically for this model. According to Audio-Technica, they are designed to produce a natural, detailed presentation with generous spatial imaging.

The open earcups also serve a practical purpose. Continuous airflow should prevent as much heat from accumulating around the ears during extended sessions. Together with a weight of 240 g, this supports the ATH-AL5NC’s role as a headphone for hours of music, work or entertainment rather than occasional short listening.

LDAC Brings Hi-res Audio to the Wireless Link

Bluetooth handles wireless transmission, with support for SBC, AAC and LDAC. When paired with a compatible source device, LDAC can transmit audio signals at resolutions of up to 24 Bit 96 kHz.

Bluetooth Multipoint allows the ATH-AL5NC to remain connected to two devices at once. A notebook and smartphone can therefore share the same headphone connection, avoiding the need to disconnect and pair again whenever the user changes source.

Noise Reduction Without Sealing Off the Listener

Electronic Noise Reduction is an unusual addition to an open-back headphone. Activated using a button on the right earcup, it is intended primarily to reduce steady background noise from sources such as air-conditioning systems, traffic or technical equipment.

Its purpose has to be understood within the boundaries of the open construction. The ATH-AL5NC neither seeks nor claims to provide the same degree of isolation as a closed Active Noise Cancelling headphone. Noise Reduction is better regarded as a way of calming persistent background interference while maintaining the more open relationship with the surrounding environment.

Audio-Technica also allows the function to remain active when the supplied audio cable is used. Noise Reduction is therefore not restricted to Bluetooth listening.

Controlling Sound Leakage – Within Reason

Sound escaping from the earcups is an inherent part of any open-back design. Audio-Technica addresses this with a Sound Leakage Reduction Mode, available through the Audio-Technica A-T Connect app.

The manufacturer is explicit about what the mode can and cannot achieve. It reduces sound leakage but does not eliminate it, particularly at higher listening levels. Activating it also changes the tonal character because the frequencies most likely to escape are reduced.

This makes Sound Leakage Reduction Mode a situational tool for shared rooms rather than a technical means of transforming the ATH-AL5NC into a closed headphone. Sensible volume levels remain important whenever other people are nearby.

An App for More Than Basic Settings

The Audio-Technica A-T Connect app provides the ATH-AL5NC’s principal adjustment options. These include an equaliser and a Low Latency Mode intended to reduce the delay between picture and sound when playing games or watching video.

Soundscape adds a selection of natural and ambient sounds for concentration or relaxation. The app is also where users can activate Sound Leakage Reduction Mode.

Built to Keep Going

Battery life reaches up to 75 hours when Noise Reduction is switched off. With the function active, Audio-Technica specifies up to 50 hours of playback.

A 15-minute quick charge provides as much as eight hours of listening without Noise Reduction. With Noise Reduction enabled, the same charging period delivers up to five hours.

Wired operation remains available through the supplied 1.2 m audio cable. It terminates in a 3.5 mm stereo mini-jack and incorporates an inline microphone and controls. A separate microphone built into the headphones supports phone calls, online meetings and voice communication while gaming.

The Most Important Advantages at a Glance

• Wireless open-back construction: The ATH-AL5NC combines the spacious character of an open headphone with freedom from the source device.
• Hi-res Audio via LDAC: Compatible devices can transmit signals at up to 24 Bit 96 kHz.
• Long battery life: Up to 75 hours of playback reduces the need for frequent charging.
• Bluetooth Multipoint: Two Bluetooth sources can remain connected simultaneously.
• Noise Reduction: Persistent background noise can be reduced during both wireless and wired listening.
• App-based adjustment: Equaliser, Low Latency Mode, Soundscape and Sound Leakage Reduction Mode are available in the A-T Connect app.
• Low weight: At 240 g, the headphones are designed with extended listening and working sessions in mind.
• Wired alternative: The supplied cable includes a 3.5 mm stereo mini-jack, controls and an inline microphone.

Price & Availability

According to the manufacturer, the Audio-Technica ATH-AL5NC has been available from specialist retailers since 9 September 2026. The recommended retail price is € 249,-.

The package includes a 1,2 m audio cable with a 3,5 mm stereo mini-jack, inline microphone and controls, as well as a charging cable.

Getting to the Point

The Audio-Technica ATH-AL5NC is interesting precisely because it does not attempt to disguise its open-back nature. Audio-Technica Ltd. adds Bluetooth, generous battery endurance and useful electronic features while acknowledging that neither Noise Reduction nor Sound Leakage Reduction Mode can overturn the acoustical realities of an open earcup.

For listening at home, in a home office or at a personal workspace, the concept has considerable appeal. The user remains aware of the room, heat should build up less readily around the ears, and the absence of a cable brings genuine freedom of movement. Anyone looking for strong isolation on a train or aircraft will still be better served by a closed-back design. For listeners who knowingly choose open-back headphones, however, the ATH-AL5NC offers a notably contemporary interpretation of the format.
