One of the best-sounding near-neutral below 200 dollar IEM that I've heard.

The BQEYZ FROST (179 USD) was sent to me through a review tour group that was conducted by BQEYZ Audio. Thank you, BQEYZ Audio.

The packaging is good and easy to open; it includes a set of wide bore eartips, a set of normal bore eartips, and a pair of foam eartips. The cable that it came with is a fixed 3.5mm but is available in 4.4mm during purchase. It also includes a very nice carrying pouch that can fit the IEM with the cable and a medium-size dongle DAC/amp.

The IEMs themselves look very good, are classy, and feel very high in quality. The shell is metal with a beautiful glass front plate. The IEM shells feel like high-end products.

The frost can take a lot of power and can go very loud without distorting; your hearing will be the limiting factor. It is easily driven with my small dongle DAC with connexant chips such as the QKZ TC MAX PRO, BGVP T01s, and BQEYZ LIN, among others. The sensitivity is average, which is good, as I like my IEMs to have similar loudness when I switch between them.

The BQEYZ FROST sounds very neutral with a slight lower bass, upper midrange, and upper treble boost, forming a slight W-shape sound signature, but very neutral sounding in general. I'm happy with the way it is tuned because it sounds very dynamic, unlike other sets that have neutral tuning but sacrificed dynamics and sound anemic.

The bass is slightly boosted. It sounds very clean, textured, detailed, punchy, and deep. It sounds very neutral and doesn't dominate or slow down the overall sound of the FROST. One of the best bass quality I've heard.

The midrange is very clean, clear, and dynamic. There is a very slight upper midrange rise, but it is never shouty; there is no frequency that suddenly jumps out at you unnaturally, indicating the use of a high-quality driver with low distortion.

The treble is handled by the micro-planar driver and sounds very extended and well behaved; there are no sharp peaks that can be heard. It has very good smoothness while having very good dynamics at the same time. It sounds transparent, open, crisp, and airy, with a hint of gentleness that can be found on good planar drivers.

The stage is slightly wider than it is deeper; it has an atmospheric sound and is certainly above average in size.

The imaging is very good; it may not be the most pinpoint imaging that I've heard, but the instruments and vocals have ample space between them that gives it a fair amount of holography, which makes the listening experience very enjoyable.

The detail retrieval and resolution are very good and certainly above average. There is a good amount of perceivable micro-details and instrument separation.

Compared to QoA Mimosa (99 USD):

The Mimosa belongs in a lower price bracket, but it has a similar driver configuration with the FROST. The Mimosa is V-shaped; it has a very boosted bass, much more than the FROST; it has a more reccessed and darker-sounding midrange; and the treble is more boosted, forming an overall more contrasty sound. I find the frost to sound more mature between the two.

Compared to BQEYZ Cloud (169 USD):

This is not a direct comparison, as I don't have it right now; this is based on memory, so I won't go too much into details over this; I can only share the general and most apparent differences. The FROST sounds more detailed and more dynamic. Both have similar near-neutral tuning.

Compared to Juzear Butterfly 61t (199 USD):

The 61t is smoother and less dynamic sounding, but the FROST is not far behind in terms of smoothness. The bass on the 61t is sub-bass focused, while on the FROST it is a balance between the mid-bass and the sub-bass. The 61t has a warmer overall tonality and a lower upper midrange level. The upper treble in the FROST is smooth, but it is even smoother on the 61t.

Compared to Letshuoer Cadenza 4 (249 USD):

The FROST sounds very neutral compared to the brighter-sounding Cadenza 4, but both exhibit similar levels of dynamism, with the Cadenza 4 very slightly ahead. The Cadenza 4 has a wider soundstage and more imaging separation, at the expense of it sounding brighter and less neutral. The Cadenza 4 seems to me to be geared toward people who like bright and vivid sound, while the FROST is geared toward people who like neutrality.

Compared to Moondrop MAY (79 USD):

They are not in the same price bracket; the May is only here due to its similarity in driver configuration with the BQEYZ FROST. The May sounds warmer and bassier, has a U-shaped sound signature, and has a laid-back detail presentation. Both of them have a very extended upper treble due to their use of microplanar drivers for the treble. The frost is more neutral-sounding in comparison.
.

Very good neutrality
very good dynamics
Beautiful and classy design
Great build quality
Nice set of accessories
Good value for money

I wish the cable was modular, but for the price, it's hard to ask.

What I really like about the Frost is the way it balances neutrality with good dynamics, as I find most neutrally tuned sets to lack energy. The FROST is a very versatile IEM that would suit the majority of listeners; it has very good and linear perceived frequency response, great musicality, low distortion, dynamic sound, good price, and so on, and for that, the BQEYZ FROST gets my highest recommendation.

Happy listening, Cheers!
