Fun Fact to start off: BQEYZ stands for Best Quality Earphones for YouZ. It’s almost like BQEYZ has a Brooklyn accent, and that’s awesome. I wish more audio companies had accents. “Youse better wise up and get some BQEYZ in ya ears”

Thank you for the review copy, BQEYZ.

Howdy y’all! Submitted for your viewing pleasure today: the BQEYZ Frost. I say “viewing” to begin here because, please flip through the album, the set really wants your attention. The whole electric blue vibe is really fun and distinctive; it would be a sin to unpair that cable from these IEMs. A lot of people in the culinary industry say “You eat with your eyes first.” Well, I feel like a set’s look can sometimes give you an idea of its sound. Thats sorta the case here with this 1 dynamic, 1 micro planar driver hybrid set. But it’s complicated. Let’s check it out.

The unboxing experience is very solid. Upon opening the box you’ll find the earphones peaking out from their foam nest, their glow beaming bright blue from beneath the glass faceplate. The glass gives the design beneath a sense of needed depth and allows light to reflect off the set from within. This is the first set I’ve ever demoed with a glass faceplate but I must say I like the concept. The cool shimmer of the glass compliments the metallic blue snowflake design beneath. This all sits atop a very nicely CNC’d aluminum shell. Over the last two weeks the earpieces have withstood two completely-intentional, on-purpose, for-science drops from about 3 feet onto a hardwood floor and are thankfully no worse for ware. These rigorous trials have led me to conclude that the build quality is pretty decent.

Yeah that’s a nice cable right there. The electric blue snake the set comes is one of the most perfectly paired stock IEM cables I’ve come across. Sets double the price often don’t come with such a match, so the Frost is definitely picking up some points for style. The cable is slightly, but not overly memory prone while being thick enough not to become tangly. The double helix design is a popular choice these days, and the chrome hardware picks up the snowflakes on the faceplate. I got a 4.4 termination, 3.5 is available as well.



In addition, the IEM comes with 2 sets of silicone eartips (atmosphere and reference), a pair of foam eartips, a hard, roomy case and a little brush. I think it’s a great accessory package for the price, although I can’t speak too much to the quality of the stock eartips. I got them to work just fine, but I have a tendency to tip roll and use my own. Today, Tangzu Tang Sancai Wide Bore.

I measured the nozzles to be 5.7mm wide at their widest point. That’s on the wider side of average, but with the non-intrusive nozzle length I easily found a comfortable fit. Please note- my ears are cavernous. However the set itself is on the more compact side when compared to many hybrid IEMs.

There’s reason attention has been called to the mid bass. But what may be just as conspicuous as its mid bass bump is this sets sub bass roll off, leading to a distinctive presentation that may catch you off guard. We’re not here for the Rumble, we’re here for the Slam. Combined with a somewhat sparkly yet unobtrusive treble and a fairly sharp rise in the pinna gain, we’ve been given an impactful and edgy set.

There’s a decent sub bass roll-off in this sets frequency response from around 50hz to 10hz that really focuses all the attention of the sets dynamic driver into producing a quick, clean mid bass attack the smacks you right in the face with every beat of a kick drum. While we may not hear too much of the lowest frequencies, tracks with lots of sub bass don’t sound anemic. The presentation of the sub bass is a soft backing canvas that makes the mid bass impact all the more affecting.

The mid bass is snappy and resolved. And attack reminiscent of BA Bass with a slower, more familiar DD decay gives the set a natural sound despite its exuberance.

We’re not really here for the vocals. That’s not to say I didn’t enjoy them, but they sit behind the rest of the presentation just a bit. “Recessed” would not be the word I’d use. Let’s go with “relaxed”. The mid range is warm and open, but it’s missing a bit of the underlying depth more subbass would bring. Male vocals can sound a touch hollow despite the warmth for this reason.

Due to that little upper mid range spike, guitars and stringed instruments are the real stars of the mid range on this set with an energetic delivery that you’ll miss when it’s not around. Female vocals have a fairly strong and defined presence, but the ring of trumpets and whistle of woodwinds tend to take precedence.

It’s accentuated, yet controlled. Well extended, but comfortable. Some of the best treble I’ve heard from a micro planar driver to be honest. Well resolved with formidable microdetail retrieval, the set boasts a treble that strikes a perfect balance between fidelity and musicality. The big 10k dip followed by a burst of air makes the set feel lively and refreshing. I found a few brighter tracks a touch sibilant, but I didn’t find it much of an issue in general. I found the treble to be the most source-dependent aspect of the Frost. A clean, neutral source is a must for controlled treble on this set. I used a DTC 800 for testing.

The soundstage is wide and spacious, but it’s not very deep. This leaves you in a slightly more intimate setting, and that sense of closeness is at the heart of this sets impact and energy. I don’t feel like I’m watching the band in the middle of a giant arena. I feel like I’m at an open mic night at a small coffee shop that’s about to get shut down for breaking all the noise ordinances. It’s a set that puts you in the middle of the action.

The demure sub bass and hybrid configuration allow the set a clarity and resolution unmuddied by obtrusive low frequencies. The set had accurate imaging with very adept instrument separation. The set handles busy tracks well for its price range, and I was only able to notice some bass distortion when turning it up to volume levels I should not be listening to music at.

I wasn’t really expecting what I got. It’s seems a sub bass roll off is a common feature of the BQEYZ house tuning, and I understand why. The snap and bounce of the mid bass is pretty addicting, and it’s rare to find a mid bass attack that quick outside of all-BA set. I listen to lots of rock, indie rock, pop, jazz and instrumental music. The Frost is great for the majority of my library, but it can sound a bit reserved on tracks that rely on lots of sub bass. If you’re the type that has more than 1 IEM (hey), this may evolve into an invaluable part of your arsenal. It’s not a jack-of-all-trades. It’s more a master of its craft. And that craft is mid bass.

I hope youse enjoyed reading, thanks!
