Three-output headphone amplifier
The Superlux HA3D is a compact headphone amplifier designed to distribute a single stereo mix to up to three listeners, each with an independent volume control and dedicated peak LED indicating when the signal approaches clipping. Balanced stereo signals connect via a pair of XLR inputs, while unbalanced sources can be connected through either a 6.35mm jack or 3.5mm mini-jack input. Only one input type should be used at any one time. A dedicated loop output allows additional HA3D units to be cascaded whenever more than three independent headphone feeds are required. Powered either by two AA batteries or an external 5–17V supply, the HA3D is equally suited to studio installations and mobile recording where mains power isn't always available. With a typical battery life of around 12 hours when driving a single pair of 75-ohm headphones, it comfortably covers extended rehearsals or recording sessions. A front-panel mono switch also allows a stereo mix to be checked in mono directly at the amplifier.

Clearly laid out connections
The Superlux HA3D's three headphone outputs are grouped on the right-hand side of the unit, keeping inputs and outputs physically separated for a clear signal flow. The first output also includes a 3.5mm mini-jack as an alternative headphone connection. Independent volume controls for all three outputs sit on the front panel alongside the mono/stereo switch, while individual peak LEDs illuminate approximately 3dB before clipping to provide a clear visual indication of available headroom. The power LED doubles as a battery-status indicator, changing from green to red when approximately four hours of battery life remain. The loop output in turn allows additional HA3D units to be connected whenever more headphone outputs are required.

Musicians, engineers, and mobile use
The Superlux HA3D is aimed at small recording sessions, rehearsal setups, and location work where up to three musicians need independent headphone feeds from a single mix source. Each headphone output uses its own amplifier circuit, allowing every listener to adjust their monitoring level independently without affecting the others. With a dynamic range of 120dB and THD+noise below 0.03%, the HA3D delivers measured performance that comfortably exceeds expectations at its price point. The aluminium alloy chassis keeps weight to 560g while providing adequate protection for regular transport. Battery operation with a colour-coded charge indicator makes the HA3D a practical standalone monitoring solution for outdoor recording, rehearsal rooms without convenient power points, and compact live rigs.

About Superlux
Anyone looking for microphones and headphones with an excellent price-performance ratio will certainly find what they are looking for from Superlux. The company employs experienced specialists and produces its articles at various locations in its own factories in China and Taiwan, where the products are developed, tested, and manufactured under one roof. Everything can therefore be manufactured on site, from the raw material to the finished device, which has a positive effect on the selling price. The products are often praised in test reports for their sound and manufacturing quality. With Superlux products, private users can achieve solid recording and mixing results even without a large budget.
Flexible source connections
Whether connected to a mixing console, audio interface, smartphone, or portable music player, the Superlux HA3D adapts easily to a wide range of monitoring tasks. In the studio, it distributes a bus mix to up to three musicians, each with independent volume control, while rehearsals and practice sessions benefit from the ability to play along with backing tracks directly from a mobile device. Additional HA3D units can be cascaded whenever more headphone feeds are required, providing an inexpensive way to expand a monitoring system as ensembles grow. Combined with its battery operation, compact dimensions, and lightweight aluminium construction, the HA3D is equally at home in permanent studio installations, rehearsal rooms, location recording, and mobile live rigs.
