EPZ's current lineup covers considerably more than traditional wired earphones.
The company sells audiophile IEMs, gaming-focused IEMs, portable DAC/amps, cables and other audio accessories, with products ranging from relatively affordable entry-level models to substantially more expensive multi-driver IEMs.
That variety creates an obvious question:
Which EPZ product actually makes sense for you?
For this guide, we've selected four notably different options:
- EPZ P40 — a 2DD + planar + PZT tribrid IEM for music listening.
- EPZ G20 Pro — an affordable USB-C gaming IEM with DSP and dual microphones.
- EPZ G30 — a hybrid 1DD + 1BA gaming IEM with multiple connection options.
- EPZ TP35 Pro — a portable dual-CS43198 USB-C DAC/amp rather than another pair of earphones.
Instead of declaring one product universally superior, we'll look at what each one is designed to do and where its specifications differ.

EPZ P40: The Most Ambitious IEM in This Group
The EPZ P40 stands apart from the other products here because of its unusual driver configuration.
EPZ uses:
2 dynamic drivers + 1 planar magnetic driver + 1 PZT piezoelectric ceramic driver.
Rather than asking one driver to reproduce the entire audible range, EPZ assigns different roles to several driver technologies.
The company says a 9mm DLC dynamic driver handles the low frequencies while a separate 7mm dual-magnet, dual-cavity DLC dynamic driver concentrates on the midrange.
A second-generation micro planar driver handles additional detail and upper-frequency extension, while the PZT element is used for high-frequency texture and air.
A four-way electronic and acoustic crossover coordinates the system.
EPZ P40 Specifications
The P40 has a listed frequency response of 20Hz–20kHz, sensitivity of 100dB ±3dB and impedance of 14Ω.
It uses a 0.78mm 2-pin cable interface and comes with interchangeable 3.5mm and 4.4mm modular plugs.
That modular plug system is particularly useful if your audio equipment includes both conventional 3.5mm and balanced 4.4mm outputs.
Who Should Consider the P40?
The P40 is the music-focused choice among these four products.
It makes more sense for someone interested in a multi-driver IEM than for a gamer whose main priorities are a boom microphone and USB-C DSP.
At the time of writing, EPZ lists it for $159.99.

What Makes the P40 Interesting?
Driver count alone doesn't determine whether an IEM sounds good.
Implementation, crossover design, tuning, fit and the interaction between the drivers all matter.
That is why we would not describe the P40 as automatically better simply because it combines several driver technologies.
What the specification does provide is a more elaborate acoustic architecture than the single-dynamic-driver G20 Pro or hybrid G30.
The P40 also includes a Furukawa silver-plated cable and its interchangeable 3.5mm/4.4mm plug system.
For listeners building a portable music setup, that flexibility can be valuable.
EPZ G20 Pro: The Affordable Gaming Option
The EPZ G20 Pro takes a completely different approach.
Instead of multiple driver types, it uses a single 10mm LCP + PU composite-diaphragm dynamic driver and adds gaming-oriented electronics and microphone functionality.
Its current price is $59.99, making it significantly less expensive than the P40.
The G20 Pro is designed around USB-C connectivity and includes built-in DAC/DSP functionality.
EPZ provides DSP EQ profiles aimed at gaming and general listening, while the microphone system gives users a choice between a boom mic and inline mic.
Dual-Microphone System
One of the G20 Pro's more useful gaming features is its three-position microphone control.
Users can switch between:
Boom microphone → Inline microphone → Mute.
That gives it considerably more communication functionality than a conventional music-only IEM.
EPZ also includes a 1.2-meter USB-C cable plus a 1.5-meter USB extension cable, providing additional reach for desktop PC setups.
Lightweight Earpieces
EPZ lists each G20 Pro earpiece at approximately 3.9 grams.
The shells are 3D printed, and the company says the shape was revised from the original G20 to reduce protrusion around the front cavity.
We have not independently tested long-session comfort, so fit will still depend on the individual ear.
Who Should Consider the G20 Pro?
The G20 Pro makes the most sense if your priorities are:
USB-C connectivity, gaming-focused DSP, a boom microphone and a relatively affordable price.
It's much less about audiophile driver complexity and much more about creating a practical gaming package.
EPZ G30: A Hybrid Gaming Alternative
The EPZ G30 moves one step beyond the G20 Pro acoustically by combining:
1 dynamic driver + 1 balanced armature.
Specifically, EPZ describes a 9.2mm DLC + PU dynamic driver for the lower frequencies and a custom 29689 balanced-armature driver for higher-frequency reproduction.
The system also uses Knowles acoustic damping.
The current listed price is $79.99.
G30 Connection Options
One of the G30's strengths is that EPZ offers both 3.5mm and USB-C configurations.
The precise microphone and digital features depend on the selected version.
The USB-C option can add a built-in DAC, DSP/EQ functionality and simulated 7.1 effects, while the product is available with inline- and boom-microphone configurations.
This means you should pay close attention to the variant selector before ordering.
Don't assume every G30 package has exactly the same cable or microphone configuration.
G30 Technical Specifications
EPZ lists:
Driver: 1DD + 1BA
Frequency response: 20Hz–20kHz
Sensitivity: 105dB ±3dB
Impedance: 14Ω
Connector: 0.78mm 2-pin
Plug options: 3.5mm / USB-C
The earpieces are listed at approximately 4.4 grams each.
EPZ G20 Pro vs G30
These two are the most natural comparison in this guide.
The G20 Pro uses one 10mm dynamic driver, while the G30 uses a hybrid dynamic-driver + balanced-armature configuration.
The G20 Pro is built heavily around USB-C gaming. It provides DSP EQ, dual microphones and an included USB extension cable.
The G30 provides more connection choices, depending on the variant, and uses its hybrid acoustic system as a key differentiator.
In simple terms:
G20 Pro: prioritize USB-C gaming features and lower cost.
G30: consider it when you want a hybrid-driver gaming IEM and/or the connection options available among its variants.
That isn't a declaration that one will sound better to every listener. We have not performed controlled A/B listening between the two.
EPZ TP35 Pro: Upgrade the Source Instead
The fourth product isn't an IEM at all.
The EPZ TP35 Pro is a portable USB-C DAC/headphone amplifier designed to sit between your source device and wired earphones or headphones.
It currently sells for $69.99.
Inside are two Cirrus Logic CS43198 DAC chips.
The TP35 Pro supports PCM playback up to 32-bit/384kHz and DSD up to DSD256.
3.5mm and 4.4mm Outputs
The TP35 Pro provides both:
3.5mm single-ended and 4.4mm balanced headphone outputs.
EPZ specifies output power at 32 ohms as:
112mW through 3.5mm
and
262mW through 4.4mm.
This pairs particularly neatly on paper with an IEM such as the P40, whose modular cable includes both 3.5mm and 4.4mm plugs.
That doesn't mean a TP35 Pro is required to use the P40. It simply gives users both output formats in one compact DAC.
PEQ and Gaming Support
The TP35 Pro isn't limited to music playback.
EPZ includes UAC 1.0/Game Mode, intended to improve compatibility with devices such as compatible consoles, along with microphone support through the 3.5mm connection when the attached headset/cable and source support it.
It also supports PEQ/tuning through EPZ's supported software/web workflow.
For someone who already owns good wired IEMs, buying a DAC/amp like this may make more sense than buying another pair of earphones.
Which EPZ Product Fits Which Setup?
These four products solve different problems.
If you're primarily building a music-listening setup, the P40 is the relevant IEM here because its design centers on its 2DD + planar + PZT tribrid configuration and modular analog cable.
For a more affordable USB-C gaming setup, the G20 Pro offers DSP, dual microphones and gaming-oriented functionality for $59.99.
The G30 occupies the middle ground for gamers interested in a hybrid 1DD + 1BA configuration and a choice of connection variants.
The TP35 Pro is different: it is for someone who already has wired IEMs or headphones and wants a portable USB-C DAC/amp with both 3.5mm and 4.4mm outputs.

What About Cheaper EPZ IEMs?
These four products aren't the entire EPZ lineup.
The current catalog also includes models such as the G10, standard G20, Q1 Pro, Q5 Pro, K5 and several considerably more expensive IEMs.
For example, the current Shop All page lists the Q1 Pro from $39.99, G20 at $49.99, Q5 Pro at $65.99 and K5 at $120.99. Prices can change.
Blog60s has already covered several of these models separately, so those individual reviews can be internally linked from this section.

What to Check Before Buying an EPZ IEM
Connection type is one of the first things to check.
A 3.5mm analog IEM and a USB-C DSP gaming IEM may look similar, but they serve different device setups.
For gaming models, also check the exact microphone configuration.
The G30 in particular is offered in multiple versions, so the USB-C boom-mic configuration shouldn't be assumed to apply to every variant.
For music-focused IEMs, consider whether you actually need balanced 4.4mm connectivity.
And with any IEM, remember that fit is highly individual. Shell shape, nozzle geometry and ear-tip selection can substantially affect comfort, isolation and perceived sound.
Shipping, Returns and Warranty
EPZ's current store pages advertise a 30-day return window, one-year official warranty, and free standard shipping on orders of $49.99 or more.
Return shipping for subjective reasons such as sound or fit may normally be the customer's responsibility unless covered by EPZ Care+ or applicable law.
Because store policies can change, check the current conditions before ordering rather than relying permanently on the terms quoted in this guide.

Final Thoughts
EPZ's lineup covers enough different use cases that choosing by price alone doesn't make much sense.
The P40 is built around a more ambitious multi-driver configuration for music listening.
The G20 Pro takes a gaming-first approach with USB-C DSP and a flexible microphone system.
The G30 adds a hybrid dynamic + balanced-armature configuration while offering different connection variants.
And the TP35 Pro addresses an entirely different part of the audio chain by upgrading the source with dual CS43198 DACs and 3.5mm/4.4mm outputs.
The right choice therefore depends less on which EPZ product has the longest specification sheet and more on what you're connecting it to and what you're using it for.
If none of these four matches your setup, EPZ's broader catalog includes additional audiophile IEMs, gaming models and accessories at several price points.
