Baum Audio has launched Ellipse, a premium closed-back over-ear headphone that moves the Danish brand from boutique guitar building into hi-fi personal audio. That background is the most interesting part of the story, because Baum is entering the headphone category from a musician-first perspective rather than from the usual consumer electronics lane.
Ellipse is designed in Denmark and priced at £359 in the UK through selected retail partners.
The headphone uses custom-tuned 50 mm dynamic drivers, a closed-back over-ear design, aluminium construction, velour, brass detailing, replaceable earpads, replaceable cables, and a 32-ohm impedance that should work across portable and desktop listening setups.
The pitch is direct: a headphone made for listeners who want comfort, isolation, and a natural presentation without getting pulled into overly technical audiophile theater. Baum is framing Ellipse around long listening windows, musical detail, and product longevity, which fits the brand’s roots in instruments built to be owned for years rather than replaced every product cycle.
A Guitar Brand Steps Into Hi-Fi Headphones
The move from guitars to headphones is a smart angle for Baum Audio. Guitar companies already understand wood, metal, ergonomics, finish quality, musician feedback, and long-term ownership. That does not automatically translate into great headphones, but it does give Baum a useful starting point for a product category where comfort and physical feel are as important as sound.
Ellipse uses a closed-back design, so the headphone should provide the isolation needed for travel, office listening, home use, and late-night music work. Baum is also claiming an unusually open presentation for a closed-back model, which is a key detail because closed headphones can sometimes feel boxed-in compared to open-back designs.
The custom 50 mm dynamic drivers are tuned for clarity, depth, and tonal accuracy, with a listed frequency response of 12 Hz to 40 kHz. The 32-ohm impedance also keeps the headphone flexible enough for everyday systems, laptops, portable players, interfaces, and desktop hi-fi setups.
Baum Audio Ellipse Is Built For Long Listening
The most practical part of Ellipse may be its repair-friendly thinking. Replaceable earpads and cables are small details, but they matter once a headphone becomes part of a daily setup. Pads wear down, cables fail, and too many headphones become waste because one replaceable part was treated like a permanent failure point.
Baum’s use of aluminium, velour, and brass detailing gives Ellipse a higher-end physical identity without turning the design into something loud or overbuilt. The Scandinavian approach comes through in the restrained shape, material choices, and focus on use rather than ornament.
There is also a dual connectivity system for shared listening, which gives the headphone a small lifestyle feature that fits casual use. That may appeal to listeners who want one pair of headphones that can move between personal listening, travel, content work, and home playback.
Ellipse feels like a sensible first headphone from a brand with real musician DNA. The category is crowded, especially around the £300 to £400 mark, but Baum Audio has a clear story here: Danish design, closed-back practicality, custom drivers, replaceable parts, and a headphone made by a company coming from the instrument world.
