THIEAUDIO Cypher Review

Synergy

Efficiency

If I were able to comfortably push the THIEAUDIO Cypher with a simple in-line dongle, theoretically, then anything will do. I did upscale power to see if one would benefit from upscaling the source.

What’s funny is that most aspects improved, including the high frequencies, which is counterintuitive since the lack of power usually affects the low frequencies more often.

But what I was hearing was improvements and subtle changes within DACs, and they do tend to limit themselves to a point where upscaling is ineffective after a certain point. That means that they’re not as gear-dependent as some other headphones.

Pairings

I would mostly consider solid-state devices with the THIEAUDIO Cypher because of their low impedance, which doesn’t fare well with some tube amplifiers that require high impedance. Plus, I would want to keep their clean aspect and not mar that with coloration.

Questyle and their Sigma is one of those devices, and so is their Sigma Pro, although tier-wise the Sigma is a better match, and it still produces the same ultra-detailed sonic presentation as a combo.

They tend to max out with gear that is within their tier, like an iFi audio ZEN DAC and ZEN CAN combo, or the Rose Technics RT-5000.

Actually, that iFi Audio combo was my favorite with the Cypher since I could engage the Xbass feature to counterbalance the low-end roll off. Plus, I could engage the Xspace as well to gain an even wider soundstage without compromising placement.

Selected Comparisons

Meze Audio 99 Classics 2nd Generation

Technical

Competition is stiff at this price tier because you have models like the Meze Audio 99 Classic Gen 2 that outperform the original version, even though the original headphone model has been considered one of the best-selling models in its price tier.

I always thought the original 99 Classics could have used some sonic improvements since it sounded a tad dark and lacked some upper-end clarity.

This is one of the virtues that version 2 has, aside from tighter bass response and a smoother midrange presentation, on top of slight comfort level improvements.

My gut feeling tells me that presently, the 99 Classics is still one of the most sold headphones around.

Most Audiophiles rarely consider closed-back models, but the 99 Classics certainly captured a large audience regardless, evidenced by over 1600 reviews over at the Amazon store. Version 2 is slowly catching up.

Design

Real walnut cups adorn most of the Meze 99 Classics V2’s appearance and is their most prominent visual feature.

Black and Gold adorn the rest of the headphone, and a self-adjusting padded headband completes the package.

Version 2 uses a larger cup size with improved, cleverly implemented, and visible venting right beside the input jack.

The top portion remained the same, a self-adjust system that I find a touch more comfortable since it arches correctly and distributes weight on a larger area, removing any pressure spots.

The 3.5mm input jacks remained and are quickly becoming the standard on most high-quality headphones.

Both these headphones can share stock cables, and there’s a plethora of aftermarket cables compatible with both models.

However, the flush mounting is preferable for the fact that the 99 Classics V2 is an ambidextrous headphone, and the only visual L and R cue you have is the markings on the cable. It does improve the plug’s durability and safeguards the cable and plug up to a certain point.

Performance

If I wanted to have some fun with music, the 99 Classics V2 is a good choice because, although in stock form it might not sound as vivid and lively as the Cypher, with equalization it becomes so, and can handle a larger amount of boost if you’re a bass lover on top of that.

But the cypher is the speedier of the two and tends to be the better headphone for monitoring purposes because of all the detail it produces.

They also produce a better soundstage and project more accuracy in placement, but remember, the Meze Audio 99 Classics V2 is a closed-back headphone and is the best candidate for those who need isolation above other things.

The high frequencies are produced more darkly on the 99 Classics V2, and the Cypher is certainly the livelier set that produces a higher level of crystallinity, speediness, and realism in the midrange section, particularly, quite notably in the vocal section.

HIFIMAN Edition XV

Technical

This is the antithesis comparison since the HIFIMAN Edition XV uses a totally different method to channel sound to the listener. At this price tier, it’s one of the most sought-after at the moment.

They use a large asymmetrical planar magnetic driver to produce larger-than-life sound. It’s one of this line’s particular sonic characteristics. The HIFIMAN XV is a large headphone, and it wants to be seen and heard.

The only recommendation I would have for those who are planning on buying the XV or have already committed is that you need or will need a better cable, although it only includes 3.5mm connectivity. Just the same, the Cypher stock cable is more meritable.

Design

The new HIFIMAN’s headband style is in play here, which, to me, looks to take top spot when it comes to durability within the HIFIMAN line. But only time will tell. So far, all the models I’ve tinkered with seem to be holding up very well.

But the general quality of the build is best on the Cypher, and I would put my money on the Cypher as far as durability. All components used to assemble the Cypher are metal, aluminum, and carbon fiber.

Clamping force is applied at a higher amount while wearing the Edition XV, and the pads, although much larger, use a stiffer foam that you feel pressed against your face. Again, those lush, soft pads that the Cypher comes with are excellent, comfort-wise.

Performance

For starters, the Cypher is the more efficient of the two, and on occasion, I had to raise the volume twice as high for Edition XV to reach the same volume level. If you use DAPs or gear that is battery-powered, the Cypher will take you further on the same battery.

Sonically, let’s start from the bottom up. The XV bass has more body and presence and tends to hit harder. The bass notes have more texture, and I prefer the low end on the XV over the Cypher’s clean, straightforward bass presentation.

As far as the midrange, the XV tends to produce warmer vocals that also occupy a larger space within the soundstage. However, I have to give accuracy and tonality to the Cypher since they tend to produce a more realistic vocal presentation.

What’s surprising here is that I have to say that the Cypher is the brighter-sounding because their high frequencies are more present and bold, plus that 2k peak area on the Cypher makes them sound forward, and they also tend to produce more micro detail in general.

The XV produces the more fun factor in its sound signature by hitting harder, with bass that’s full-bodied, and their life-like sonic panorama, but the Cypher wins in vocal realism and acoustic instrument verismo.

Sennheiser HD 550

Technical

The Sennheiser HD 550 was released almost simultaneously with the HD505, nicknamed Bronze, and I quickly recognized the series of Sennheiser headphones they birthed from.

The Sennheiser HD 5XX line is extensive and would take me a while to mention them all. They’re a well-established design that Sennheiser keeps improving on and is now many years into production and a well-established line.

Design

The HD 550 wears the 500 series design, which is entirely made of polymers. I can say that of all the headphones I’ve owned from this series, which were plenty, I have never had an issue with parts of the headband cracking or any other similar issues.

The oval cups and pads are rather stiff, but the design is such that it wraps itself around your head. It’s an unconventional design, unique, that works as far as comfort.

The Cypher carries a conventional headphone design that’s well implemented as far as comfort. But again. The Cypher takes the pole position in comfort and build quality all the way home.

Performance

It’s an amazing feat that Sennheiser accomplished here with the smallest driver in the bunch.

They tuned the small 38m driver to produce such an ample amount of bass that it’s on par with most headphones within the price class it sits in. Even against the XV, which has a driver with four times the radiating surface.

They also handle a considerable amount of boost in the lower regions without going into cone breakup or distortion. In general, they don’t distort, but don’t do anything particularly great either, because they’re a very well-balanced set.

They play well with most music, including EDM, and they can do Jazz and Rock, especially classic rock tracks. They do a good job with most genres. But they don’t excel in any category.

The Cypher might be more specific and not be the best for jamming over the weekend, but they certainly present vocals and acoustic instruments that are closer to real. They also produce better highs that are vivid but not offensive.

The Sennheiser HD 550 is the balanced set and can be considered a jack of all trades, but a master of none. The Cypher has vocals going for them, clean highs, plus detail retrieval as virtues. You can always detune that 2k peak.

My Verdict

I interpreted the semi-open-back dynamic driver THIEAUDIO Cypher concept as a headphone designed deliver a high-quality build standard with high levels of audible detail, and a natural ability to let you listen to whatever you’re feeding them in an uncolored way. On that basis, it met all those objectives.

The THIEAUDIO Cypher is one of the ones to watch in this tier now, in my opinion. They deliver on vocal delivery, neutrality, micro-details, and subtle bling.

It’s a rare occasion to find a headphone with such build quality, and that sounds this good for the posted asking price. The THIEAUDIO Cypher is a headphone that should help you decisively narrow your wish list if you’re currently shopping around.
