Reviews
What owners and reviewers say
independent video reviews on this page
Umbral is new and extremely limited, so no full independent review exists yet. Early listeners at audio shows describe excellent build and comfort, fast and tight bass, and a lively, treble-forward tuning. It is very power-hungry: plan for a high-power desktop amplifier.
What they love
- Build quality and comfort described as excellent
- Tight, fast bass from the planar driver
- A world-first planar + MEMS hybrid design (Headphonesty)
- Collectability: 99 individually numbered units
Worth knowing
- It needs a high-power desktop amplifier; a phone or portable player will not drive it
- Open-back: it leaks sound and does not block outside noise
- Treble-forward tuning, so treble-sensitive listeners should audition first

FAQ
Your questions, answered
What amplifier do I need?
Umbral is a low-sensitivity planar headphone (84 dB/mW). A high-power desktop amplifier is recommended, ideally 10 W or more single-ended. It will not reach its potential from a phone or portable player.
Does it block outside noise?
No. It is an open-back headphone, so sound passes in and out. That is what gives it its wide, natural stage, and why it is best in a quiet room.
Which cable termination do I get?
The 2 m cable comes with your choice of 6.3 mm, 4.4 mm or 4-pin XLR plug. Choose it above when you add Umbral to your basket.
Which ear pads should I use?
The sheepskin pads give a fuller bass and a more focused sound; the ice-silk pads feel cooler and more open for long sessions. Swapping takes seconds.
How limited is it?
Unique Melody is making 99 units worldwide.
How fast is delivery?
Delivered by DHL Express in 5–7 working days.
What warranty and returns do I get?
A 2-year BOLLSEN warranty handled by our UK & EU team. Returns within 14 days with the hygiene seal unbroken. Your statutory rights are not affected.
