The sound
Airy treble, deep stage, fine detail
Airy, finely detailed treble, clear vocals and a deep, three-dimensional stage, with three bone-conduction drivers adding tactile bass and depth.
BOLLSEN sound map, summarised from independent reviews.
Maybe not for you if you are treble-sensitive or want big, warm bass; the MEST MKIII CF Blue has softer treble and the MEST Jet Black more bass slam.

Inside Unique Melody

Reviews
What owners and reviewers say
Headfonics, custom version
About Audio and a detailed Head-Fi review hear the MEST Fortune as an airy, highly detailed flagship with a deep, holographic stage and some of the best treble in the MEST line. The main caveat is balance: bass is tidy rather than big and the treble focus may not suit sensitive ears, though Headfonics found its custom version warmer and richer.
What they love
- Treble with electrostatic air but real body (Head-Fi)
- Deep, spherical, holographic stage (About Audio)
- Clear, airy vocals with sibilance kept in check (Fox Told Me So)
- Tactile, layered bass that reviewers credit to bone conduction
Worth knowing
- Moderate bass quantity; bassheads may want more
- Treble-led tuning can tire treble-sensitive ears
- Vocals can lose some body when the bass is busy (Headfonics)
Summarised from Headfonics, About Audio, Head-Fi review, IEMRanking (reviewer scores).

FAQ
Your questions, answered
Is the MEST Fortune warm or bright?
Reviewers differ. About Audio and Head-Fi hear the universal version as airy and treble-led, while Headfonics found its custom version warmer and richer. Most agree on tidy bass, clear vocals and a big, deep stage.
Does it need a powerful player?
No. At 10 Ω and 107 dB it runs well from any good player or dongle, but reviewers found it scales with more power and pairs nicely with warmer sources.
Which plug does it come with?
The cable is included and ends in a 4.4 mm balanced plug, the connection dedicated music players and balanced DACs use. If your source only has a 3.5 mm socket, add a 4.4 mm dongle DAC or ask us which one suits you.
Do the two colours sound different?
No. Purple and Red share the same drivers and tuning; only the shell and cable colour differ.
Which ear tips should I use?
Try every size in the box before judging the sound. The right tip sits snugly without pressure, and that is when the bass fills in and the treble settles.
Universal or Custom Fit: which should I choose?
Universal Fit arrives fast and uses ear tips. Custom Fit is moulded to your ears: a perfect seal, steadier bass and the strongest bone-conduction effect.
How does ordering a Custom Fit work?
Choose Custom Fit and order. We email our 3D-scan guide, a hearing specialist near you takes a 3D ear scan or ear impressions (usually charged separately), and your monitors arrive by DHL Express 3–4 weeks after we receive them. Not right? We arrange a free refit.
How fast is delivery?
Universal Fit is delivered by DHL Express in 5–7 working days. Custom Fit is made to order: delivered 3–4 weeks after we receive your 3D ear scans.
What warranty and returns do I get?
A 2-year BOLLSEN warranty handled by our UK & EU team. Universal Fit can be returned within 14 days with the hygiene seal unbroken. Custom Fit is made for your ears, so instead of a change-of-mind return you get a free refit. Your statutory rights are not affected.
