Choosing between the EPZ G20 and G30 is not as simple as picking the more expensive model.
Both are wired gaming IEMs with detachable 2-pin cables, microphone options, USB-C functionality, and lightweight resin shells. However, there are meaningful differences in their driver configurations, connection options, included accessories, and price.
The G20 currently costs around $50 and uses a single 10mm dynamic driver. The G30 moves to a hybrid 1DD + 1BA configuration and costs around $80.
That $30 difference raises the obvious question: what exactly do you get by moving from the G20 to the G30?

The Biggest Difference: Single Driver vs Hybrid
The most obvious hardware difference is inside the earpieces.
The G20 uses a single 10mm silicone + PU composite dynamic driver.
The G30 instead uses a hybrid configuration consisting of a 9.2mm DLC + PU dynamic driver and a custom 29689 balanced armature, together with Knowles acoustic damping.
In principle, a hybrid design allows different driver types to handle different parts of the frequency range. EPZ positions the G30's dynamic driver around lower-frequency reproduction and the balanced armature around higher-frequency detail.
However, more drivers do not automatically mean better sound.
Driver implementation, crossover design, acoustic tuning, fit and individual listening preferences all matter. For that reason, the G30's 1DD + 1BA architecture should be viewed as an important design difference rather than proof that it will sound better to every listener.

Gaming Features
Both products are explicitly positioned by EPZ as gaming IEMs.
EPZ markets the G20 around competitive gaming, directional information and keeping smaller details such as footsteps distinguishable during louder effects. The G30 is similarly marketed around positional information and separation, with its hybrid driver architecture being one of the major differentiators.
These descriptions are manufacturer claims rather than gaming-performance measurements conducted by Blog60s.
Both models also use wired connections, eliminating the Bluetooth latency considerations associated with conventional wireless earbuds.
For competitive players, however, the difference between G20 and G30 may have as much to do with connectivity and configuration as with the drivers themselves.
Connectivity: G20 Has an Important Advantage
This is one of the easiest differences to overlook.
The G20 includes both a 3.5mm cable and a USB-C cable in the standard package.
EPZ also includes a USB adapter. That means a G20 buyer can move between compatible analog and USB-C devices without choosing one cable configuration at checkout.
The G30 works differently.
EPZ currently sells the G30 in separate configurations:
- USB-C with boom microphone
- USB-C with inline microphone
- 3.5mm with inline microphone
The selected G30 configuration determines the cable supplied. EPZ explicitly states that buyers receive only the cable option selected at purchase.
That makes the G20 package more flexible out of the box.
The G30 provides more configuration choices, but buyers need to know which connection and microphone setup they want before ordering.
USB-C DSP and Digital Features
Both models offer additional functionality through USB-C.
The G20's USB-C connection incorporates DSP, and EPZ currently describes Gaming, Cinema and Music sound modes.
The G30 USB-C version also supports DSP/EQ functionality, but EPZ additionally lists simulated 7.1 surround processing and customizable EQ features for the USB-C configuration.
The important distinction is that these digital features depend on using the appropriate USB-C setup.
A buyer using the analog 3.5mm connection should not expect USB-C-specific processing features to remain available.

Microphone: The Details Matter
Both G20 and G30 can provide a boom microphone, but the implementation and purchasing options differ.
With the G20, EPZ includes a USB-C cable supporting the detachable boom microphone and a separate 3.5mm cable with an inline microphone.
The G30 is sold in multiple variants. Its USB-C boom-mic version provides the detachable boom microphone, while inline-microphone configurations are also available. EPZ states that the boom microphone is USB-C only.
A boom microphone places the microphone closer to the user's mouth than a typical inline microphone, but Blog60s has not independently tested the microphone quality of either model.
For buyers who specifically want a boom mic, the key difference is therefore purchasing convenience:
G20: the appropriate boom-mic USB-C cable is already part of the dual-cable package.
G30: make sure you select the USB-C boom-microphone version.
Design and Comfort
The two IEMs share several basic design ideas.
Both use lightweight 3D-printed resin shells and detachable 0.78mm 2-pin connections.
EPZ lists the G20 at approximately 4.5 grams per earpiece, while the G30 is approximately 4.4 grams per earpiece.
The 0.1g difference is unlikely to be meaningful by itself.
More importantly, comfort cannot be determined from weight alone. Ear shape, shell geometry, nozzle fit and eartip selection can have a much greater effect on long-session comfort.
Neither model can therefore be declared universally more comfortable based solely on its specifications.
What Do You Get in the Box?
This is another area where the two products differ considerably.
EPZ G20
EPZ currently lists:
- G20 IEMs
- USB-C cable with boom-mic support
- 3.5mm cable with inline microphone
- S/M/L eartips
- USB adapter
EPZ G30
EPZ currently lists:
- G30 IEMs
- One cable corresponding to the selected configuration
- Carrying case
- S/M/L eartips
- USB adapter
- Boom microphone with the applicable boom-mic version
The G20's advantage is dual-cable flexibility.
The G30's package adds a carrying case, but it does not give buyers both primary cable types by default.

G20 vs G30 for Music
Neither model is restricted to gaming.
Both can be used for music, movies and general media, but their internal architectures differ substantially.
The G20 relies on its single 10mm dynamic driver, while the G30 combines dynamic and balanced-armature drivers.
EPZ describes the G30's hybrid arrangement as using the dynamic driver for bass impact while the balanced armature contributes higher-frequency reproduction.
That makes the G30 technically more complex, but technical complexity should not be confused with guaranteed listening preference.
Someone who primarily listens to music should consider tuning preferences alongside driver configuration rather than choosing solely by driver count.
For buyers whose primary use is music rather than gaming, it may also make sense to compare these models against music-focused IEMs at similar prices.
Price Difference: What Does the Extra $30 Buy?
At the time of this comparison, EPZ lists the:
G20 at $49.99
and the:
G30 at $79.99
That creates a price difference of approximately $30.
The additional money primarily moves the buyer from the G20's single dynamic-driver architecture to the G30's hybrid 1DD + 1BA configuration, along with the G30's different cable construction and additional USB-C features such as simulated 7.1 support.
But spending more also introduces a tradeoff.
The less expensive G20 includes both its 3.5mm and USB-C cables, whereas G30 buyers select one cable configuration when purchasing.
So the G30's higher price should not be interpreted as a straightforward upgrade in every category.
Choose the G20 If...
The G20 may better fit your needs if:
- You want to spend around $50 rather than $80.
- You want both 3.5mm and USB-C cables included.
- You regularly switch between different devices.
- You want a detachable boom microphone without having to choose a special package configuration.
- You want USB-C DSP functionality but do not specifically need the G30's hybrid driver architecture.
- Simpler single-driver construction appeals to you.

Choose the G30 If...
The G30 may better fit your needs if:
- You specifically want a hybrid 1DD + 1BA gaming IEM.
- You are comfortable spending around $80.
- You want the additional USB-C features offered on the G30, including simulated 7.1 processing.
- You already know whether you need 3.5mm or USB-C.
- You want a carrying case included.
- You are interested in EPZ's more advanced gaming-IEM configuration rather than simply maximizing the number of included connection options.

EPZ G20 vs G30: Key Takeaway
The G20 and G30 approach the same gaming-IEM category differently.
The G20 emphasizes flexibility at a lower price. Its $49.99 package includes both 3.5mm and USB-C cables, USB-C DSP functionality and boom-microphone support.
The G30 emphasizes a more complex acoustic and digital configuration. For $79.99, it moves to a hybrid 1DD + 1BA driver system, while compatible USB-C configurations add features such as EQ support and simulated 7.1 processing.
The tradeoff is that G30 buyers need to select their cable and microphone configuration when ordering, while the G20 includes both primary cable types in one package.
For that reason, the useful question is not simply which model costs more. It is whether you prioritize the G20's included connectivity options or the G30's hybrid architecture and additional USB-C capabilities.
