The BQEYZ Frost, the final piece of the Seasons series lineup we featured here, has made its way to my desk. Right off the bat, it’s clear this isn’t just another IEM—it’s a statement. From its elegant design to its sound, it promises something special. But does it deliver? Let’s find out. For this review, I paired it with the R4 DAP and used both atmospheric and “Reference” eartips to explore its full potential.
Technical Specs and Setup
For my tests, I used the Frost with the R4 as the source. I tried both the atmospheric eartips and the “Reference” gray eartips to explore how the tonality shifts. These two combinations reveal different facets of the Frost, from stage width to frequency response.

Sound Performance_
Bass
The bass on the Frost is tight, clean, and detailed. In Death Note (feat. ichika), the bass guitar shines, giving a tactile presence that feels alive. It doesn’t quite dive into sub-bass depths, but the balance and control more than make up for it. Tracks like Pendulum – The Island Pt.1 (Dawn) reveal its rhythmic precision, blending electronic and organic bass elements with impressive resolution. The Frost feels right at home here, delivering a bass experience that’s more about accuracy than sheer power.
Mids
This is where the Frost really flexes. The mids are rich, clear, and effortlessly emotional. Listening to Many Shades of Black, I was struck by how well it positions rock elements alongside brass and percussion. The vocals? Stunningly lifelike, as if the singer was right in front of me. With Shaka Ponk – Monkey on the Wall, the Frost effortlessly captured the blend of French flair and hardcore energy, supported by a wide, immersive stage. If you’re a fan of detailed, forward mids, this IEM will keep you hooked.
Treble
The treble is where the Frost reveals its technical side. In Hans Zimmer – Opening Medley: Driving, the solos and duos come alive with crisp, sparkling clarity. However, when the track gets busy with all 96 instruments going at once, things can feel a bit dense. That said, the level of detail it uncovers is remarkable—I even caught Zimmer’s bouzouki in the mix, a testament to the Frost’s resolving power. The treble is detailed without becoming harsh, though it leans more analytical than relaxed.
Soundstage and Imaging__
The Frost’s soundstage is one of its standout features. Tracks like Witchcraft immerse you in a 180-degree panorama, something I didn’t expect from an IEM in this price range. The imaging is equally impressive—each instrument has a defined place, and vocals are centered and natural. It’s almost like wearing a pair of over-ear headphones, which is a rare treat for an in-ear design.
Dongle Result__
HiBy R1, Questyle m12i and 5/100 volume level is enough to get a full and satisfying result. Now, Frost is at the peak of the mountain it visited. There isn’t a technical parameter left untouched! And the fanatic crowd at live recordings came alive, so the instruments too. You know what? Giving the Frost clean power is what is essential to get the eargasmic experience.
Pros:
• Incredible detail retrieval and resolution.
• Very wide, airy soundstage with precise imaging.
• Rich, emotional mids with great vocal clarity.
Cons:
• Sub-bass lacks some depth.
• Can feel congested in very dense tracks.
BQEYZ Frost Review Conclusion
The BQEYZ Frost is a masterclass in balancing technicality and musicality. It offers a soundstage and level of detail that punch well above its price point, with mids that feel alive and treble that brings out every nuance. While the sub-bass might not satisfy those looking for rumble, its accuracy and control make it a joy to listen to across a variety of genres.
The choice of eartips adds another layer of flexibility. The “Reference” tips bring out more analytical detail and treble sparkle, while the atmospheric tips round things out with a more natural, relaxed presentation. Whether you’re a technical listener or someone who just loves getting lost in music, the Frost has something to offer.
In short, the BQEYZ Frost is a worthy contender in its price range and a solid choice for anyone looking to explore a refined and detailed sound signature. It’s not perfect, but it’s darn close for what it sets out to do.
