About Build, Design

About Build, Design, Comfort

The Abyss Diana Phi open-back headphones are well built and tuck away nicely into their small case these are our initial impressions. The headphones are very lightweight, so there’s no neck fatigue even after hours of listening. The earcups fold flat for storage in the leather carrying case, ensuring they arrive at their destination undamaged.

As with any headset, if you have a big head or a lot of hair on your neck, the head pressure from the headband might be uncomfortable.

This is pretty much the same shape and style but the driver is now the same driver as their flagship headphone, the Abyss AB 1266 Phi TC (original Diana). That is some seriously hardcore planar technology fused into a funky looking small headphone

I found that adjusting the earcups by folding them on a flat surface made enough room to accommodate my earrings and allowed for more comfort all around. For those who do not have earrings, flexible earcups are adjustable for any head size.

The Diana Phis DMS Pad Mod is very comfortable to wear for hours, even during long flights or domestic travel. I found the headphone that fits every head equally well, enough not to allow sound leakage but not so much as it causes discomfort.

The ear pads are covered with leather and are soft and comfortable for about an hour of listening, after which they start to ache. There is no relief even by changing sides or adjusting the ear pads’ placement on your ears.

The driver design allows Diana Phis to offer a fantastic voice with plenty of bass response. The high notes are clear and crisp, and the midrange is right on point with the vocal.

The headphones go very loud, even at such a low volume level detected by the audio file’s software. However, as with any headset, the Diana Phis lack the imaging and depth that external speakers or open-backed headphones can offer.

The included headset cable is detachable and connects with the left earcup via a range 2.5mm jack plug, color-coded for easy identification (the right earcup contains all electronics, including the battery).

The cable is thin and very plasticky, though it does not feel cheap. The Accessories cable itself must be inserted into the left earcup with care, or else they can get stuck inside and tug on the internal electronics when pulled out.

I could understand the need for extended battery life in wireless headphones, but this one seems excessive. The battery allowed me to listen for about 28 hours.

In my opinion, the much cheaper Linner NC50 offers a much better trade-off between voice quality and battery life without having to recharge every few hours.

Diana Phi’s material is a mix of luxury and practicality. I noticed throughout that none of these materials are heavy-weight, which Abyss made sure to avoid. The headband slider is created of super-light carbon fiber and looks excellent. The Alcantara is very thin and perfectly stitched.

The headband does seem to have just the right amount of length for my head and I consider mine on the small side. Clamping The clamping pressure is spot on for me. Not too much but enough to prevent downward pressure on the top of the ear which is where I always find fit issues to be at their least comfortable with headphones.

The cups are coated in a gunmetal glazed ceramic finish, which has proven to be very scratch-resistant. Although the matching grey-tone leather pads are small and not very deep, they have a sturdy funnel shape that allows for full circumaural voice. It’s brilliant indeed.

Cable & Connectors

Connectors

A removable bass has opted for 2.5mm mono plugs for the connectors. Some might feel that 2.5mm plugs are a little on the weak side, which is true when you think of connectors like the flush-mounted Hifiman designs on the older Susvara and HE1000 V2.

Accessories cable is a must for portable headphones, but they can also be a pain to manage when it comes to making an upgrade.

The Diana Phi DMS Pad Mod has a short male-to-male 3.5mm connector with red/blue woven fabric sleeving and L/R markings. While I appreciate the color coordination, I would’ve preferred to see some more color variety between left and right so I could tell them apart quickly.

The cable terminates into a 2.5mm connector on its end, with the other small side having two 3.5mm connectors (one of which is used for microphone functionality).

Stock Cables

Now the stock cables are 4-core braided designs with a standard plastic y-split and glossy sheathing by Jps labs. I found the stock cable to be excellent in terms of construction and quite flexible, even if they do feel a little on the thin side. The lack of stress relief makes me worry about how long these will last if I’m not careful with them.

That is a plus for the supplied stock cable with the Diana Phi ( (DMS Mod) because they are finished to a very high standard indeed.

The chin slider is a small piece of rubber that slides well and provides enough friction to hold the cables in place. However, it can be a little bit difficult to use as you have to pull outwards on the y-split first. Then there’s the microphone built into one of the cables and can be used to answer calls.

Performances

Performance

The Diana Phi DMS Pad Mod has an excellent frequency response with deep bass and crisp highs, accentuated in songs with calls and accessories that play in the mid frequencies.

The sounds are pretty clean, with only a minimal amount of background noise-induced distortions at very high volumes (when you feel like you’re about to blow your ears away).

The Diana Phi DMS Pad Mod has flagship-level performance when it comes to delivering clear mids and highs. They can get loud, but don’t lose quality when they get loud. The bass is also imposing, and you can hear the lows with a lot of clarity. if you have a smaller head, you may find there’s more bass presence

The tonal balance of the Diana Phi is highly dependent on how one wears them, with different positions giving different results. I preferred using them over-the-ear, which provides a better bass frequency response.

Diana’s clarity comes to the fore and you feel a very direct connection to the voice. The tonal balance is neutral, so it’s neither rich nor too lean the sounds are uncolored.

The Diana Phi has an average soundstage and imaging performance due to its semi-open design. Instruments can be discerned from one another pretty quickly, but it lacks a sense of depth and imaging accuracy to make this easy.

Speed & Dynamics

For the instantaneity of each tone’s initial leading edge, the Diana Phi headphones are some of my favorite. It is once again up there with flagship planars, and I believe it may be even faster. It sounds clean, precise, and well-controlled.

The Diana Phi is also suitable for dynamics. It’s a single-sided, planar magnetic headphone that is better than average. Although it does not slam as hard or as loud as the Focal and ZMF dynamic driver headphones (or the ZMF dynamic driver headphones), it is still a solid planar magnetic headphone. It’s slightly behind the Audeze LCD-4, the HiFiMAN Susvara, and the HiFiMAN Susvara, but it is ahead of all the egg-shaped HiFiMAN headphones such as the HE-1000se.

Soundstage & Imaging

The soundstages performance of the Diana Phi is very dependent on how one uses it. I experienced its narrowest soundstage when wearing them over-the-ear, but most people will probably wear them straight down or with an angle between the two.

While it does feel closed in, there’s enough space for instruments to be able to breathe and slightly sound distinct from one another, especially with rock and pop songs. Imaging performance is also a fair bit for a semi-open headphone, but the lack of depth does hinder it from being precise.

EQ

The Diana Phis have an excellent voice signature overall. EQ adjustments can be made to make them even better, with the bass and highs being most affected when adjusting the 2-band EQ on my smartphone.

The impact of these adjustments depends on the sound played and how far one goes when one makes them. I felt that no more than -2 dB for bass and -2 to 0 dB for highs was sufficient.

Timbre

It is essential to distinguish timbre between a material- and transducer-related analysis and frequency responses-related analysis. The first considers timbre an analogy to instruments that have a different pitch or tone.

The latter feels the impact of the headset on the resonance and playability of tools in the recordings being listened to. The latter can be considered tonality or tonality balance in many ways. It is how the headset affects tools.

It may be that material and transducer-related timbre is captured by frequency response. There may also be some correlation for specific characteristics of planar magnetic headphones compared to dynamic driver headphones. However, I am not aware of any particular area of frequency response or behavior we could call timbre.

The Diana Phi type has no problems with material and transducer-related timbre. This means that it doesn’t feel dry or unnatural due to the planar magnetic headphones.

The frequency response-related resonance is, however, very unpleasant and strange. It has a steely, shimmery voice familiar with recordings of tools with higher frequencies, such as cymbals. We’ll see why this is so by looking at the frequency response below.

Diana Phi Review

“The Diana Phi are generally positive, with many people claiming that it is one of the best sounding earphones their money can buy. Some even think that its voice signature is so good, it could be used as a reference point for other manufacturers to target when making a new product. Of course, some caveats have to be considered for these headphones to shine.

The main one being that they have a very high impedance of about 5 Ohms, so a reputable source with a powerful amp is needed for them to voice their best. I found that my LG V20 smartphone with the ESS Sabre ES9218P DAC/AMP handled them just fine and didn’t need any additional amplification.

Comfort & Isolation The matching perforated black leather pads, though small on the outside and not that deep, have a clever but sturdy funnel shape that expands in such a manner to deliver a full circumaural experience. You could possibly weigh in on the isolation from both outside noises as well as a sound leak at moderate listening levels. It is this was the answer to my long search for flagship-level performance without the flagship level weight and comfort issues.

“Diana Phi is primarily positive, with the majority of users finding it to have a good voice which they claim is on par with most high-end headsets in its class, I really like leather pads, it is very comfortable. This comes as no surprise as this product has been reviewed several times online by reputable sources, so many people have had an opportunity to listen to it and provide comments.”

” The Diana Phi is pretty positive as users find its good voice, design, and comfort level very good for a headset of this price range. The one negative thing about this product that I’ve seen mentioned by quite a few people is its cord, which seems too thin and feels fragile. It would’ve been nice to see a more durable design likes the one that comes with the Focal Elear instead.”

“The Abyss Diana headset is a radical performer, but given the company’s history, that was to be expected. The original Abyss, the AB 1266 Phi CC, hit me like a ton of bricks when I first heard it in 2013. I find that the Diana Phi fits into this top tier category for detail retrieval, however, I’d place it closer to the bottom of this category than the top of the category.  And it remains the best-sounding headset I’ve heard, but Diana is a lot smaller and more portable. We got a few months now under our belt to get beyond our initial impressions and give you the full skinny in this review.

Comparisons

Focal Utopia ($4000)

The Focal Utopia’s Diana Phi is slightly more detailed. However, the Utopia has a better frequency response, tonal balance, and slightly better dynamics. The DMS pad mod makes the Diana Phi lighter and more comfortable to listen to for more extended periods.

HiFiMAn Susvara ($6000)

The Diana Phi after EQ, in my opinion, is a direct competitor for the HiFiMAN SUSvara. These headphones are the only ones in the top-tier flagship crazy detail category that are comfortable to wear for extended periods, other than the HE1000se. The Susvara has a better tonal balance and soundstage and more information for bass and treble.

The Abyss Headphones Diana Phi is less detailed, lighter, has DMS pads, and lasts longer, but I have not seen either of them fail. The Susvara is worth a $2000 range price more if you don’t feel comfortable with EQ. However, it is a solid competitor if you can do it or find a way to adjust 10khz on Diana Phi (when paying close attention).

Audeze LCD-4 ($4000)

The LCD-4 has better bass detail and slam than the Diana Phi, but the mids are comparable to the Diana Phi. Although the LCD-4 has a better bass extension, it sits lower than the Harman shelf. However, with the Diana Phi, I found that certain positions increased the bass quite a lot.

The LCD-4 has great treble detail, and its voice is cleaner than the Diana Phi. However, the LCD-4’s tone balance issues aren’t as granular on the Diana Phi. So maybe that’s why the LCD-4 is so good. The LCD-4 is a great headphone, but the weight is too much. I’d rather have the Diana Phi than the LCD-4. Both need some EQ, however.

Conclusion

The Diana Phi open-back is a lively, exciting headphone that provides excellent voice, which might be lacking in some areas but more than makes up for it with its punchy lows and crisp highs.

It’s not too picky when it comes to sources so that you can hook it up to smartphones and DACs alike, but you might need a headphone amp for its sounding to be sufficient.

The Diana Phi is best suited for those who listen to genres like rock and pop, where calls and acoustic accessories play in the mid frequencies. We hope that our abyss headphones review can help you learn more about this gear.
