The EPZ Q1 Pro is a budget wired IEM built around a single 10mm dynamic driver, a lightweight 3D-printed resin shell, and a detachable 0.78mm 2-pin cable.
At around $39.99 at the time of research, it sits in one of the most competitive parts of the IEM market. Instead of using multiple drivers as a marketing feature, EPZ has kept the Q1 Pro relatively simple: one dual-magnetic, dual-cavity dynamic driver using an LCP+PU composite diaphragm.
Buyers can also choose between 3.5mm and USB-C versions, making the Q1 Pro relevant to both traditional audio devices and newer phones or tablets without a headphone jack.
But specifications alone do not tell us whether a budget IEM is a good fit for a particular listener.
Review note: Blog60s has not conducted hands-on testing of the EPZ Q1 Pro. This article is a research-based review using manufacturer specifications, publicly available product information, customer feedback, and clearly identified sources. Manufacturer claims and third-party observations are not presented as independent Blog60s measurements or listening tests. Prices, ratings, availability, and specifications may change over time.
EPZ Q1 Pro at a Glance
The Q1 Pro is positioned as an entry-level wired IEM for everyday music listening.

10mm LCP+PU Dynamic Driver
The core of the Q1 Pro is its 10mm LCP+PU composite dynamic driver.
EPZ describes the driver as using both a dual-magnetic and dual-cavity structure.
LCP stands for liquid crystal polymer, while PU refers to polyurethane. The diaphragm construction is one part of the driver's overall acoustic design.
But diaphragm material alone does not determine whether an IEM sounds good.
Driver implementation, acoustic chamber design, damping, venting, nozzle geometry, and tuning all contribute to the final frequency response.
That is why the Q1 Pro's single-driver configuration should not automatically be considered inferior to inexpensive multi-driver designs.
More drivers do not inherently mean better sound.
Sound Characteristics
Because Blog60s has not performed a controlled listening test of the Q1 Pro, we do not assign our own subjective sound signature to it.
EPZ describes the Q1 Pro as having clear mids, controlled lows, and smooth highs, with tuning intended to work across different music styles.
The manufacturer also publishes a frequency-response graph measured by EPZ Acoustic Laboratory using a Brüel & Kjær 4128C Head and Torso Simulator. That measurement should be understood as manufacturer-provided data rather than an independent Blog60s measurement.
In practical buying terms, the Q1 Pro is being positioned as a general-purpose IEM rather than a highly specialized monitor aimed at one narrow genre.
Listeners who require a very specific bass, midrange, or treble presentation should still consult independent measurements and listening impressions before purchasing.
Resin Shell and Design
One of the Q1 Pro's more distinctive characteristics at this price is its shell construction.
EPZ says the Q1 Pro uses skin-friendly resin and the company's 3D-printing process.
The supplied product images show a glossy dark shell paired with a blue decorative faceplate.
The shape follows the familiar contoured IEM approach rather than a simple earbud-style enclosure.
There is also a metal nozzle assembly, while the cable connects through a detachable 2-pin interface.
The detachable design matters because a damaged cable does not necessarily require replacing the entire IEM.
Comfort and Fit
EPZ describes the Q1 Pro as lightweight and intended for longer listening sessions.
The contoured shell is designed to sit inside the outer ear while the cable routes over the ear.
Actual comfort remains highly individual.
Ear shape, nozzle angle, insertion depth, ear-tip size, and cable routing can all affect how comfortable an IEM feels.
The included S, M, and L ear tips provide some ability to adjust fit and seal, but no universal shell shape can guarantee identical comfort for every listener.
A proper seal is also important for sound. A poor seal can significantly alter perceived bass response.
3.5mm vs USB-C: Choose the Right Version
This is one of the most important purchasing details.
The Q1 Pro is sold with either:
3.5mm single-ended
or
USB-C
connectivity, depending on the version selected.
These should not be confused with a package that necessarily includes both connection types.
The 3.5mm version is the straightforward option for devices with a conventional headphone output or for listeners who already use their own DAC/amp.
The USB-C version is intended for modern phones, tablets, laptops, and other compatible devices without a 3.5mm jack.
EPZ states that the USB-C version incorporates a CX31988 DAC.
Choose the connection type based on the equipment you actually plan to use.
Detachable Cable
The Q1 Pro uses a 0.78mm 2-pin detachable cable, a common connection standard among wired IEMs.
EPZ specifies a 1.2-meter, four-core LEONI single-crystal copper cable.
The Q1 Pro uses a detachable 0.78mm 2-pin cable.
A detachable cable provides two practical advantages.
First, the cable can potentially be replaced if it becomes damaged.
Second, owners can change cables later if they need a different termination or physical configuration, provided the replacement is compatible with the IEM's connector arrangement.
Cable material itself should not be treated as proof of a dramatic audible improvement. For everyday ownership, replaceability and ergonomics are generally easier benefits to establish.
Is the Q1 Pro Easy to Drive?
The Q1 Pro is specified at 32Ω impedance and 110dB ±3dB sensitivity.
EPZ positions it as suitable for ordinary devices without requiring substantial additional amplification. Its official guide similarly describes it as easy to use with common phones and laptops.
For many buyers, that is appropriate for the product's intended role.
The Q1 Pro is designed as an accessible everyday wired IEM rather than a demanding audiophile headphone that requires a powerful desktop amplifier.
The USB-C version further simplifies use on compatible devices by incorporating its own DAC.
What About Gaming?
The Q1 Pro is primarily presented as a music-oriented budget IEM rather than a dedicated gaming model such as EPZ's G-series products.
That does not prevent it from being used for games.
A wired connection avoids some of the latency concerns associated with Bluetooth audio, and a comfortable IEM can be useful for longer gaming sessions.
However, Blog60s has not independently tested the Q1 Pro's imaging, positional accuracy, or competitive gaming performance.
Buyers primarily interested in features such as boom microphones, gaming DSP modes, or dedicated FPS tuning should look at purpose-built gaming models instead.
What's in the Box?
EPZ currently lists the Q1 Pro package as including:
- One pair of Q1 Pro IEMs
- One cable
- Carrying bag
- S/M/L ear tips
The Q1 Pro package includes the IEMs, cable, ear tips, carrying bag, and packaging.
The accessory set is relatively straightforward, which is reasonable for an IEM positioned around the $40 level.
Customer Ratings
At the time of research, EPZ's official product page shows 15 customer reviews, while the company's store listing displays approximately 4.93 out of 5.
Customer ratings can provide useful ownership context, but they are not controlled acoustic tests.
They can also change as additional reviews are submitted.
For that reason, the rating should be treated as a snapshot of current customer feedback rather than proof of objective sound quality.

Who Should Consider the EPZ Q1 Pro?
The Q1 Pro is primarily aimed at listeners looking for an inexpensive first step into detachable-cable wired IEMs.
It may be relevant if you want a budget IEM for everyday music, commuting, videos, laptop use, or general listening without moving into a much higher price category.
The choice between 3.5mm and USB-C also gives buyers some flexibility depending on their source device.
Listeners who want a dedicated gaming microphone, complex multi-driver architecture, premium metal construction, or a more specialized audiophile design may want to look further up the market.
Is the EPZ Q1 Pro Worth Considering?
At approximately $39.99, the Q1 Pro combines a 10mm LCP+PU dynamic driver, 3D-printed resin shell, detachable 0.78mm 2-pin connection, and a choice of 3.5mm or USB-C configurations.
The design is relatively simple, but that is not necessarily a weakness.
At this price level, a well-implemented single dynamic driver can make more sense than adding extra drivers simply to increase the specification count. EPZ itself uses the Q1 Pro as an example of keeping entry-level IEM architecture simple in its current budget-IEM guide.
The main decision is therefore less about driver count and more about whether the Q1 Pro's feature set, connection option, fit, and manufacturer-described tuning align with what you want from an inexpensive wired IEM.
For buyers seeking an accessible entry into replaceable-cable IEMs at around $40, the Q1 Pro is a model worth examining.
