Detail you can listen to for hours.
The most balanced MEST: ten drivers, four electrostatics and bone conduction, in carbon fibre and Cobalt Blue.

Maybe not for you if you want hard-hitting slam for metal or EDM, or bright treble: try the Maven III.

Reviews
What owners and reviewers say
independent video reviews on this page
Reviewers praise its resolution and its wide, deep, holographic stage, and Headfonics calls it the strongest midrange in the MEST line. The honest caveats: it is very sensitive to ear tips, the nozzle is fairly wide, and some reviewers expected more slam at this price.
What they love
- Excellent resolution and quiet micro-detail (headphones.com)
- Wide, deep, holographic stage with precise imaging (IEMRanking)
- The most natural vocals in the MEST range (Headfonics)
- Non-fatiguing upper mids and treble
Worth knowing
- Very tip-dependent: try every tip in the box, and foam-like tips such as AZLA work well
- The 6 mm nozzle may feel wide in smaller ears
- Bass impact is refined rather than hard-hitting

FAQ
Your questions, answered
Does the bone-conduction driver make a difference?
It adds a subtle sense of depth and texture rather than a separate sound, and you notice it most with a deep, sealed fit.
MEST MKIII CF or MEST MKII?
MKIII CF is more balanced, with better mids and softer treble. MKII has more sub-bass and sparkle. Similar technical level, different character.
Do I need an amplifier?
No. A good dongle or music player is enough; a neutral, balanced 4.4 mm source suits it best.
Is there a Custom Fit version?
No. Unique Melody makes the MKIII CF Blue as Universal Fit only. For a custom-moulded MEST, look at the MEST Jet Black or the MEST Fortune.
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.
