It has been almost exactly a year since we first got our hands on the incredible award-winning Abyss Headphones Diana Phi. Here was a technically brilliant yet very small or ‘portable-sized’ planar headphone that was so resolving and revealing that for most other firms this would be their no 1 product.

The fact it is the no 2 product in their line-up speaks volumes about how highly regarded the full-size Abyss AB-1266 is by both the company and their customers.

The new Diana V2’s lineage, however, is not a cheaper Phi, but an improved original Diana. As such, it is more affordable than the Diana Phi at $2995, making it Abyss’s cheapest headphone offering to date. It also sports some improvements over the original Diana including updated drivers, bigger pads and a thinner headband inspired by the Phi.

Tech Inside

The Abyss Diana V2 may look similar to the Phi but internally they are not. The weight difference could be a clue at 20g lighter than the Phi because externally there is virtually no difference in the materials and design save for the pads and colors.

The technical specifications are also a clue with a slightly higher resistance level of 42Ω compared to the 32Ω of the Phi. I would, therefore, presume that even though this is still a very large 63mm planar driver for its diminutive size, it is not the same driver as the Phi with its origins closer to the original Diana.

In fact, Abyss confirmed as such by stating that work was done on the original V1 driver in optimizing the trace pattern to the magnetic field to improve its resolution. The rough guide is a half-step away above the V1 and below the Phi in terms of performance.

The Phi uses the ultra-low mass AB-1266 Phi CC driver so this one is a little weightier with a slightly thicker diaphragm. I will be curious to see in the main review if that means it really needs more power or not as both are rated at 91dB SPL.

That configuration does mean the volume or current is going to make a difference to your pairings. The Diana V2 has all the trappings of a portable headphone aesthetic with its super funky looks, but it still retains the performance specs of a flagship headphone. I think amps will feature heavily for anyone wanting to buy one.

Unboxing & Accessories

There is not a huge difference in the unboxing experience comparing the Diana V2 with the Phi. Having not reviewed the original Diana I can’t comment in detail but from the looks of it we have moved from a plainer black box to the Phi white box though the accessories seem to be similar.

It is the graphical design and use of white that I like most about the Diana box design. It feels fresh, and on the side, and I still think it conjures images of the Houston Astro’s famed 70’s outfit for those that remember it.

The one small upgrade is the imagery on the Diana V2 box is printed right into the vinyl covering whereas the Phi box I received has a sticker graphic. A small but pro upgrade.

That accessory line-up has not changed and for a $1k reduction in price that is a nice feature to retain from the more expensive Phi sibling.

This includes the 1.5m 3.5mm terminated cable with a 6.35mm adaptor but you can order them with different lengths and terminations when buying the Diana V2. You can opt for 2m, 2.5m, and 3m lengths as well as a 4-pin XLR, 2.5mm and 4.4mm terminations.

Both the cable and the headphones still come in that gloriously retro carry bag or ‘man pouch’ that the Phi uses. This is a double zipper soft nylon and leather finished carry case that fits the design aesthetic of the Diana V2 perfectly.

Inside, there is a protective dark foam inset with enough dips and contours to allow the Diana V2 to nestle safe and secure from unintended drops and movement. On each side, there is an internal flap or pocket where you can insert the cable and protect the drivers from contact.

This particular sample is the Black Onyx version but the Abyss Diana V2 does come in 2 other finishes including coffee and Arctic White. At the time of writing, Artic White does not seem to be available to order, just the first two.

If you are new to the Diana series of headphones and like a bit of urban chic then the V2 is tailor-made for you. To get to this size and weight and deliver such a ‘big sound’ is just surreal. If I sound less surprised than you then it is simply because I went through the wow phase already with the Phi version.

The basics remain in place but also one or two tweaks that represent a solid leap over the original Abyss Diana and a slight physical refinement of the Phi.

Just to remind you the Diana V2 is a 350g (20g more than the Phi) full circumaural open-back planar headphone with full-sized 63mm planar drivers but it is tiny in every other way. They are not kidding when they call this the “thinnest boutique headphone in the world’.

The Abyss Diana V2 still retains that exquisite retro aesthetic with the square-like cups that have aggressively curved corning and a clever mix of leathers and soft Alcantara finishing stretched over low-profile black-toned aluminum frame. There are very few moving parts in this design which I think actually improves it looks immeasurably.

The open-back plate grills also have an attractive Fibonacci pattern that blends right into the main cup housing. It does not feel tagged on or bolted in so the design looks seamless.

The material used on the Abyss Diana V2 are a blend of practical and luxury and are to the same standard as the Phi version.

The one theme I have noted throughout is that none of the materials used are heavy-weight designs, something I think Abyss was very careful to avoid.

For example, the headband slider is a very attractive and super-light carbon fiber finish. The Alcantara wrap is also thin, very thin indeed but immaculately stitched in a matching black color. One thing different from the Phi finishing is the lack of pattern holes in the Diana V2 Alcantara wrap. It is a plain black all the way around this time.

The Abyss Diana V2 aluminum cups are coated with a polymer ceramic finish and colored either in black or coffee depending on what you bought.

Cable & Connectors


The Abyss Diana V2 uses the same 2.5mm mono plugs for the connectors as the Phi. The connection system is a highly contoured socket recessed into the base of the Abyss Diana V2 cups with a matching contoured jack and barrel system on the cables.

This wedge-like socket, when connected to the cable, makes for a much stronger connection that is less likely to break. It also makes for a very low-profile exit point so it doesn’t look ‘tack-on’ and cheap.

The one caveat from my Phi experience? Aftermarket cables from 3rd party supplies are harder to fit because of the limited barrel width. You need a very thin barrel.

Stock Cable

You get a choice of stock cables depending on your likely usage scenario. The choice is more termination and length than actual materials because technically the wire is the same no matter what termination you choose.

Termination options included 3.5mm, 2.5mm, quarter-inch jack, 4.4mm, and XLR 4-pin on the jack side. For length, you can opt for the stock 1.5m if you are planning on moving around and then 0.5m incremental increases to 3m for home use. There is a $50 additional fee on the checkout price for every 0.5m you add onto the cable.

Before Abyss there was JPS Labs, which, if you do not know, was and is a cable manufacturer. That is a plus for the supplied stock cables with the Diana V2 because they are finished to a very high standard indeed. For this review, we received the 3.5mm version with a quarter-inch jack converter and the XLR 4-pin, both in 1.5m formats.

Cable Finishing

The finishing on the stock cable is a thick but pliable rubber jacket sheath over a 24AWG custom copper alloy conductor which then splits into 2-wire per channel beyond the metal-Y-split using a transparent thinner jacket.

The 2.5mm barrels are uniquely shaped to fit into the base socket of the Abyss Diana V2 so they can lock cleanly. It does not mean the sockets are proprietary but they are quite narrow so thin 2.5mm dual-entry alternatives will work such as the Hifiman Single crystalline stock but nothing wider.

Though it matters less on open-back headphones, the stock cable is 100% microphonic free even above the Y-split. There is also an easy cable to work with having no memory retention or none of that annoying stiffness or flyaway quality you find on other stock headphone cables.

On Your Head

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. A very smart design indeed.

If you are coming from the original Diana these are upgraded and bigger pads so they are much more comfortable. Also, compared to the Phi, they are slightly softer than the original grey pads. Abyss are no longer selling those grey pads so all new Phi and V2 headphones will come with these new slightly more malleable versions.

Out of the box, I can feel a physical difference from the older grey to the newer black pads with slightly less vertical pressure and biting into the sides from the lateral pressure. The clamping is the same so I am presuming the softer pad structure is dissipating in a more even manner than the stiffer edges of the older grey pads.

Initial Sound Impressions

(Initial Sound Impressions formed using a dCS Bartok integrated amp & DAC, Chord Hugo 2 and a Lotoo PAW Touch Gold & 6000 DAPs).


My gut reaction is that the Abyss Diana V2 isn’t going to differ from the Phi in terms of voltage and current requirements. The SPL is the same at 91dB and on the Bartok, it is about 6dB more efficient than the Susvara using the 6.35mm connector. That is comparing to the Susvara in balanced output on high gain (+0dB) from the Bartok.

I can still get a satisfactory level of volume from both the Lotoo DAPs actually so it is not unworkable from a portable source. On high gain, the PAW Gold Touch was running about 65-80 (min-Max) and slightly higher on the PAW 6000.

For now, I am calling the Abyss Diana V2 transportable desktop level in terms of amping requirements. It sounds beautiful and optimal on the Bartok and loud enough on a good quality DAP but lacking a little in weight compared to the Bartok.


So far, the difference in tuning between the Diana V2 and Phi sort of reminds me of moving from a Sabre DAC to an AKM DAC at a very crude level. The Diana V2 seems more forgiving and weightier on the low-end. Timbre is a shade richer, smoother and more even-harmonic biased. This is the AKM with its planted fuller sound and stronger bass fundamentals.

The Phi is the Sabre. It is cleaner, more neutral but with a higher degree of separation and perceived pace to its transient response. It is also the more resolving of the two headphones. The mids are more vivid and the treble is peppier and more extended sounding. The Phi might be the tougher one to pair for synergy but probably the more rewarding experience if you have the right setup.

The Diana V2 comes across as more flexible for synergy with amps. It has a signature that gels with both portable neutral well-powered DAPs as well as natural sounding beasts such as the dCS Bartok.

This version delivers on a non-fatiguing yet very resolving sound signature. I could listen to this one for hours and I probably will.

Stay Tuned!

It may be less expensive but the Abyss Diana V2 is not a cheaper version of the Phi sound. The V2 has its own definite sound signature or tuning that makes it more palatable for those without big high-end amps or want something a bit more relaxed/musical sounding.

The additional low-end weight and warmth will certainly make this easier to pair to a wider range of amps. Having said that, it is not a portable version of the Phi, it still needs amping to sound optimal.

I suspect the price point and tuning might tempt some Empyrean and Ether 2 fans into some no-pressure demo’s so we will take a look at those comparisons also.

For now, I need to leave this running for about another 50-100 hours max just to see if there are any changes as we move along to the main review. Stay Tuned!
