Build & Design

The BQEYZ Frost has a solid, well-made feel thanks to its aluminium alloy housings. They feel durable in hand, which is always a good sign. The faceplates have this interesting frosted texture that gives them a distinct look – it's a nice touch. Overall, the design is clean and modern, without being overly flashy. It's clear they put some thought into how these things look and feel.

Cable

The cable that comes with the BQEYZ Frost feels pretty decent. It's not super thin or flimsy, so it doesn't feel like it's going to break on you right away. The connectors seem solid too. It's a functional cable, for sure. Personally, though, I'm not a huge fan of the blue colour. With the overall aesthetic of the Frost being kind of frosty and silvery, a white or silver cable would have matched way better. It's a small thing, but it would have made the whole package look a bit more cohesive.

Fit & Comfort

The BQEYZ Frost is pretty comfortable to wear. They're lightweight, so you don't really feel them weighing your ears down. They fit my ears well, and I didn't have any issues with them feeling like they were going to fall out. The shape is pretty ergonomic, so they sit nicely in the ear. One thing I did notice, though, is that the seal isn't the absolute best. Passive noise isolation isn't the best, so they don't block out a lot of outside noise.

Tip-Rolling

The stock tips are nice and good, but I prefer to use DUNU Candy and Final E Pink tips for my review. The listeners may use their preferred tips for their preferred sound.

Sound

The BQEYZ Frost presents a balanced and enjoyable sound signature, making it a versatile option for various genres. The sound is warm and inviting, creating a pleasant listening experience.

Bass

The bass is textured, clean, and well-controlled. It prioritizes quality and control over quantity, making it suitable for most genres but perhaps not ideal for dedicated “bassheads.”

Sub-Bass

The BQEYZ Frost has decent sub-bass performance. According to their frequency chart, the Frost shouldn’t have much of a sub-bass presence, but it is there, and its presence truly makes the listening fun.

It does not have an earth shatteringly rumble, but has decent presence, depth and good extension. Fortunately, it does not bleed into the mids, or sound muddied due to it being well-controlled. However, it may not satisfy “bassheads” as the Frost sub-bass is about quality over quantity.
The sub-bass adds good colour and character to tracks, which makes the listening extremely fun and engaging.

Mid-Bass

The mid-bass is clean, textured, punchy and tight. It does not overwhelm the other parts of the sound, and stays in its own lane. It has powerful tactile feedback, and is neutral. Moreover, its attacks are quick, well-controlled; it doesn’t feel sluggish, which really elevates the listening experience.

Furthermore, the mid-bass, has good heft in it and is impactful. Frost’s mid-bass shines in the response speed, and it is able to keep up with complex tracks easily.
The mid-bass adds good body to tracks, which makes the Frost incredibly enjoyable to listen.

Vocals

Male Vocals

Male vocals are rich, clean, clear, detailed and natural. It has good note-weight and is full-bodied. There is no muddiness or congestion in the lower pitched male vocals, as the bass is well-controlled. Moreover, it has good warmth and outstanding clarity.

The vocals are textured and well-preserved. Also, it picks up the singer’s nuances accurately. Furthermore, the vocals have good separation from the tracks instruments and sounds sweet to the ears. The vocals stay clear and well separated regardless of instruments in complex tracks.

Female Vocals

The female vocals have warmth, incredible clarity, and are smooth, lush sounding, energetic and airy. The vocals have no harshness, sibilance, or peakiness. Moreover, the vocals are stunningly clear, has good extension and is emotionally engaging.

It feels like the singer is singing directly to you, and has an outstanding surrounding feel. It feels like the vocals are coming from all sides; feels like a blast of refreshing air, and vocals swarming all around you. Finally, the slight upper mid-range adds a sweetness and airiness to female voices without making them sound shrill or harsh.

Instruments

The instruments have good separation, clarity and are detailed. It has a nice natural timbre, which makes the instruments sound natural without excessive colouration. Individual instruments can easily be distinguished within the mix. The instruments also do not sound congested or mashed together. This sort of instrument sound truly enhances the listening experience.

Treble

The treble is a highlighted feature of the Frost. It has incredible extension, airiness, detail, and clarity. It is also smooth, and well controlled to avoid harshness or sibilance. Moreover, the treble is so detailed and clear that it allows the listener to hear the shimmer of cymbals, subtle nuances in tracks and the delicate overtones of stringed instruments.

Soundstage & Imagining

The Frost has a soundstage that is incredibly wide. It has good depth, which allows the listeners to perceive the relative distance of different instruments and vocals within the mix. This adds to the overall sense of immersion and engagement.

The Frost excels in the imaging department! The listener can precisely perceive the instrument placement within the soundstage. Moreover, it has remarkable separation, allowing listeners to clearly understand the vocals, and instruments in a streamlined and non-congested way.

Finally, the Frosts soundstage and precise imaging creates a holographic sound, where the instruments and vocals are placed in a 3D space, which makes the listening extremely immersive and expressive.

Technicalities

Dynamics

The Frost exhibits decent dynamics, performing reasonably well in microdynamics, capturing nuances in quieter passages. Macrodynamics are also handled well, with the IEM capable of handling crescendos and impactful moments without sounding constrained.

Transient Response

The transient response is decent, contributing to clarity and detail, particularly with percussive instruments. It keeps up with complex tracks excellently.

Detail Retrieval

Detail retrieval is tuned good enough to expose subtle elements in a track without becoming overly analytical or harsh.
The Frost preserves the details without obscuring the way the track is mastered. It does not accentuate the details, but lets them appear within the global picture.

Conclusion

The BQEYZ Frost is a very solid all-rounder that sounds really nice and balanced, with plenty of detail, a surprisingly wide soundstage, and seriously good imaging. The bass is punchy yet controlled, the vocals natural and clear, and the treble detailed but not harsh, mainly handling most genres well. I appreciate the solid build and comfortable fit.
If you're a real basshead the Frost might not be exactly right. But for the majority of folks wanting a good, balanced listen with some pleasant technical chops, the Frost is definitely worth a look-ESPECIALLY at this price.
