Gaming headsets are not the only option for competitive gaming. For players who prefer a lighter setup, gaming-focused in-ear monitors can provide a compact alternative while still offering microphones and features designed for PC, console, and mobile gaming.
The EPZ G20 is one such option. Priced at around $50 at the time of writing, it combines a 10mm dynamic driver, detachable cables, USB-C DSP functionality, and a detachable boom microphone.
It also stands out for its connectivity: EPZ includes both USB-C and 3.5mm cables rather than forcing buyers to choose one version.
So what exactly does the G20 offer, and who is it designed for?
Review note: Blog60s has not conducted hands-on testing of the EPZ G20. This review is based on manufacturer specifications, published measurements, customer feedback, and publicly available product information. Prices and specifications may change over time.

The specification sheet reveals one of the G20's main advantages: flexibility.
Instead of being restricted to one connection, buyers receive two cables. The 3.5mm option provides conventional analog connectivity, while the USB-C cable adds digital connectivity and DSP functionality.
Design and Comfort
The G20 uses a seamless 3D-printed resin shell rather than the large over-ear design associated with conventional gaming headsets.
EPZ lists each earpiece at approximately 4.5 grams, making the G20 particularly lightweight.
The shells also incorporate pressure-relief vents. These are intended to reduce the pressure sensation that can occur when wearing sealed in-ear monitors for extended periods.
Comfort remains highly individual, however. Ear shape and eartip selection can significantly affect how an IEM feels, so specifications alone cannot guarantee a comfortable fit for every listener.

Two Cables Are One of the G20's Strongest Features
One of the most interesting aspects of the G20 is what comes in the box.
EPZ supplies both a 3.5mm cable and a USB-C cable.
The 3.5mm cable is useful for devices with conventional headphone outputs, while the USB-C cable provides a direct digital connection for compatible computers, phones, tablets, and handheld devices.
The USB-C cable incorporates DSP functionality, with EPZ describing selectable sound modes for gaming, movies, and music.
This makes the G20 more adaptable than an IEM that provides only a standard analog cable.
The earpieces themselves use a 0.78mm 2-pin detachable connection, so the stock cable is not permanently attached to the IEM.
What About the Microphone?
Microphone functionality is particularly important because the G20 is marketed as a gaming IEM.
There are actually two microphone arrangements depending on the cable being used.
The USB-C configuration supports the detachable boom microphone. Positioning the microphone closer to the mouth can be advantageous for voice chat compared with an inline microphone positioned farther down the cable.
The included 3.5mm cable instead provides an inline microphone.
This means buyers should pay attention to which connection they intend to use. The detachable boom microphone is associated with the USB-C setup rather than being universally available through both stock cables.

Sound Characteristics
The G20 uses a single 10mm silicone + PU composite dynamic driver.
EPZ markets the tuning toward competitive gaming, particularly the ability to distinguish directional information such as footsteps while preventing louder effects from overwhelming smaller details.
Manufacturer descriptions should not be treated as independent acoustic testing, however.
Published third-party measurements provide some additional context. Measurements shared by a Head-Fi reviewer indicate a somewhat mid-forward presentation, controlled bass and relatively balanced treble. The reviewer also reported low measured distortion.
Those characteristics could make sense for a gaming-focused IEM, where midrange information and positional cues may be more useful than exaggerated bass.
However, frequency-response measurements cannot fully determine how an individual listener will perceive imaging, soundstage, comfort, or positional accuracy.
Gaming vs Music
Although the G20 is primarily positioned as a gaming product, it can also be used for music and video.
Its USB-C DSP functionality is particularly interesting here because users are not necessarily limited to one tuning profile.
For someone purchasing an IEM primarily for competitive gaming but also wanting to listen to music from the same device, that versatility may be more useful than buying an extremely specialized gaming-only audio product.
Dedicated music-focused IEMs at similar prices may still appeal more to listeners whose main priority is critical music listening rather than gaming features.
What Comes in the Box?
According to EPZ, the standard package includes:
One pair of EPZ G20 IEMs
USB-C cable with boom microphone support
3.5mm cable with inline microphone
USB adapter
S/M/L eartips
The inclusion of both primary cables is important because it reduces the need to immediately purchase an additional cable or adapter for common setups.

Customer Ratings
At the time this review was prepared, EPZ's product page displayed a rating of approximately 4.8 out of 5 from 37 ratings.
Customer ratings should not be interpreted as controlled product testing, but they provide another useful source of information when considered alongside specifications and independent reviews.
The number of ratings and average score can also change as additional customers submit feedback.
EPZ G20 Pros and Cons
Pros
Both USB-C and 3.5mm cables are included
Detachable boom microphone available with the USB-C setup
Lightweight resin shells
Detachable 0.78mm 2-pin cable system
USB-C DSP functionality
Multiple sound-use cases beyond gaming
Competitive price around $50
Cons
Boom microphone functionality is tied to the USB-C setup
Fit and comfort will depend on individual ear shape
Players wanting wireless connectivity will need to look elsewhere
Gaming-oriented tuning may not suit listeners primarily seeking a music-focused IEM
DSP features depend on using the USB-C connection
Who Is the EPZ G20 For?
The G20 makes the most sense for someone who wants a lightweight wired gaming setup without committing to a traditional over-ear headset.
It may be particularly interesting for PC and mobile gamers who can take advantage of USB-C connectivity and the detachable boom microphone.
The included 3.5mm cable also increases its usefulness for devices that still provide a conventional headphone connection.
On the other hand, users specifically looking for wireless gaming audio or an IEM designed primarily for critical music listening may want to consider alternatives.
EPZ G20 vs G30: Should You Spend More?
The G20 is not the top model in EPZ's gaming lineup.
EPZ also offers the G30, which moves from the G20's single dynamic-driver configuration to a hybrid 1 dynamic driver + 1 balanced armature arrangement.
At the time of writing, the G20 is listed at $49.99 while the G30 is listed at $79.99.
That approximately $30 difference makes the two models natural competitors within EPZ's own lineup.
Whether the G30's different driver configuration and other changes justify spending more cannot be determined from price or driver count alone.
We will examine those differences separately in our EPZ G20 vs G30 comparison.
Conclusion
The EPZ G20 combines several practical features at around the $50 price point: a lightweight resin construction, detachable 2-pin cables, both analog and USB-C connectivity, DSP functionality, and a detachable boom microphone for its USB-C setup.
Its strongest argument may therefore be versatility rather than any single specification.
For gamers moving away from bulky over-ear headsets, the G20 presents an interesting wired alternative. Its dual-cable package also makes it easier to use across different types of devices.
The available specifications, published measurements, and customer feedback make it a product worth investigating in the affordable gaming-IEM category, but prospective buyers should still consider their preferred connection, microphone requirements, ear fit, and whether gaming or music is their primary use.
Next: EPZ G20 vs G30 — we'll examine what changes when moving from the approximately $50 G20 to EPZ's more expensive hybrid gaming IEM.
