I messaged them to ask about the new stuff and their automatic reply message said 2 new IEMs by the end of July. I hope one of them is that tribrid you mentioned. I'm VERY interested in that. The flagship K9 as well but that's probably going to be out of my budget for a bit.
EPZ 530 IEM
The versatile player has come to town and is ready to take some names. Powerful, delicate, one of emotion, and a hint of sizzle are just a few ways to describe the EPZ 530 IEMs. Stay with me as we traverse the cosmos and learn more about these IEM. The price tag is a shocker!
What are the specs
Technical Details
Unit

Plug type
0.78mm double pin
Plug diameter
2.5/3.5/4.4 Canary headphone cable
Frequency response
20Hz-20000Hz
Sensitivity
115db (±0.05dB)
Impedance
32Ω
The EPZ 530 is hands down one of the most comfortable universal IEMs I have used, that I can wear for hours at a time.
The 530 houses 2 Sonion 38AM007 & 1 Sonion 2389 & 1 Sonion ED05 & 1 Sonion E50DT BA Drivers in Black Walnut Wood at a price tag of $530, with your choice of a green or orange body.
Additionally, the EPZ uses a high-quality “Canary Cable” allowing the use of a balanced 2.5 mm, balanced 4.4 mm, and single-ended 3.5 mm connection. Thus, never leaving you out in the cold.
Get ready for the storm, for something is starting to brew!
Now to the music
For this review, I used an iPhone 13 Pro Max, an iPad M2 Air, and Qobuz as my music source. For IEM’s I used Aful Performer 8’s, Penon 2’s, and Fir Audio V x Vs. Sources were the iFi Audio Go Bar, and the Topping 50 Desktop Stack (DAC/AMP).
On the 1…2…3… for our first track we start with Billy Cobham’s “Shadow,” an excellent masterpiece of percussion, the snap of the snare, run of the toms, groove of the bass, air of the keys, warmth of guitar, all topped off with the vocals of Gregg Kofi Brown to make perfect harmony.
Passion, emotion, and an ethereal fore and aft between interments make up “Secret World,” by Peter Gabriel. The waning yet defined guitar is ever present with all BA drivers. Not to be dramatic. The bass guitar is strong with the EPZs and never muddy. When needed can drive the song with drive the song as lead. Very interesting from my perspective.
For our closing selection, I chose Christian McBride’s “Getting’ To It,” a multi-piece jazz band showcasing brass, guitar, and drums, and is recorded supremely. The EPZs can capture every detail, as if one were there in the studio, from the natural decay of the horns, strike of the drums. The solos were captured quite well with each musical phrase and note expelled from each instrument.
The included IEM cable while not high-quality, does an adequate job especially since it is not microphonic.
The physical design of the EPZs was comfortable for those late-night jams where you can wear them for hours at a time. This is not the case for most IEMs.
Additionally, I feel the EPZ breaks the mold in they can play almost all genres and play them with gusto. Whether it be a bass-laden track, screaming guitars, vocals smooth as silk, or the thwack of a drum kit. The EPZ 530s can play it and play it with detail.
Suggestions
This one was difficult as I am nitpicking on the EPZ. If I had to find fault with the 530s, the cable would come to mind. The IEM cable is not microphonic but is inexpensive for a pair of IEMs in the $500 range.
The second and only other minor complaint would be the eartips but this is reaching. What eartips a person uses is completely personal.
Final Thoughts
Coming in at $530 the EPZ 530 IEM is not for the lightweights but is easily recommended. The EPZs are easily on the same playing field as other $500 IEMs and Kilobuck IEMs. Well done EPZ, well done. I look forward to their next offering in or above the $500 range.

My review of the EPZ 320 and TP20 pro
EPZ 320 – A very good mid centric iem
Pros
- Excellent Male and female vocals
- Good mid bass
- Good sound overall across the frequency
- Above average technically
- Good pairing with TP20 Pro
Cons
- Lack of treble and bass extension
- Doesn’t scale enough with better amps

Before I start, I would like to mention that most of my impressions of the gear is based on the source and test tracks mentioned, so YMMV.

EPZ 320
Fit and comfort:
EPZ 320 shells are crafted using DLP (Digital Light Processing) 3D printing technology with medical-grade resin, these are small in size and should be a good fit for majority of people without any issue. The shells have a striking red and blue color indicating right and left respectively.
Treble –
We expect very good treble response when we are dealing with multi BA configuration and I can attest that is the case here, the highs are good on this with ample details, there is a bit lack of air in my experience but otherwise the clarity and brightness is done well. With TP20 Pro, 320 produces excellent details, with the XP1, these highs are bit smoothened.
Mids – The mids are the star of the show of this iem, the moment you start listening to vocal centric tracks, you will fall in love with this iem, I can call it mid centric in terms of its focus on vocals and instruments like acoustic guitar. Both male and female vocals sound natural and organic. I can happily recommend this set to anyone with a budget of $200 who wants a very well done mids. With either of my sources, mids sounded natural though with TP20 Pro, there was more bite and edge.
Bass – EPZ 320 has mid bass focus more than sub bass, you can feel lack of extension in the bass wherein it doesn’t really rumble, it produces sub bass but just that it doesn’t really pound on you, the mid bass thump can be felt, especially with Bollywood tracks, the bass is enjoyable. XP1 helped to produce better sub/mid bass than TP20 pro through which the bass came a bit leaner in comparison
Technicalities Timbre and Tonality – EPZ320 has a hint of BA timbre (again based on its driver configuration) and I am a DD fan so have heard iem in this price range do better timbre but again the driver specs were different. The imaging is good and with good spacing between instruments, I would have liked a bit more air and stage, it has above average stage in this price range.
Reference Tracks – The Hills (Weeknd), Numb (Linkin Park), Believer (Imagine Dragons), Florescent Adolescent (Arctic Monkeys), Hymn for the weekend (Coldplay), Heavy Headed (OAFF & Kayan), Woh Kisna hai (Jasleen Royale), Dil Se Re (Dil Se), Toh Phir Aao (Awarapan), Malhari (Bajirao Mastani), Beautiful People (Ed Sheeran feat. Khalid), Billie Jean (Michael Jackson)
Overall –
EPZ 320 - I really liked my time with this iem, I have a playlist of vocal centric tracks which are from the 90s and I absolutely loved it on 320. Above average technically and inoffensive sound.
TP20 pro – apart from the mobile interference faced a couple of time with my iphone, I like the pairing with 320, it helps 320 achieve that bite and clarity, 4.4 has a bit more volume but doesn’t really add any further resolution or impact but we are talking about $80 dacamp, can be a good consideration with a middle ground kind of sound signature between AKM and ESS dac chips.
