Design and comfort

These headphones are very unusual. Even if you are familiar with the Stax family, this unit looks very particular (this is not an electrostatic, though, but a dynamic). Starting from the shape, to the materials, to the build quality itself, everything looks and feels high-end. The designers behind these headphones are the same as the AKG K1000 (Mr Heinz Renner and Mr Ryback)! I don’t know if the head-band (with the MYSPHERE logo on it) is made of aluminum, but it feels really solid and it could even be steel. You can stretch it without any fear of breaking it. The padding is detachable and it’s not bad, even though it’s a little bit slim: you may find it uncomfortable for long periods of listening. The frames are detachable too, and they attach magnetically to the body: this modularity may help with any kind of problems or breakings. The materials used are also waterproof and very solid, so it’s probably difficult to have build quality issues anyway. Speaking of comfort, they feel a little bit heavy and the clamp is pretty hard, so you get a great stability, but you must have a particular shape not to feel too fatigued after some time. I don’t find them uncomfortable, though: for this kind of product, I think they actually feel solid more than fatiguing.

Sound

I’ve personally tested the 3.1 version (15 Ohm) and  the 3.2, which has an impedance of 110 Ohm. The 3.1 version is meant to be driven by DAPs and tube Amps, while the 3.2 by solid state Amps (more or less).

I’ve personally used as sources: SMSL 32bit/384KHz DSD512 Tube headphone amplifier( that work quite good with the 3.1 pads that are very easy to drive even with my Opus2. Obviously a better amplification will give you more control and fuller soundstage.

The great thing about the modularity of these headphones is the possibility of opening the frames and get an open-back headphone. Even with the frames closed, you have a very airy sound, but the soundstage is not that wide. By opening them, it widens and deepens, and you get an incredible sense of space and a precise yet holographic imaging. I have to admit it’s more like listening to speakers than listening to headphones. Nothing I’ve tried before feels that wide and all-around-you. The isolation, even when the frames are closed, is poor, but these headphones are obviously meant to be used at home, so I don’t feel this as a problem. On the other hand, as always, when you open the air passage (more or less like using wide-bore tips on in ear monitors), you lose some bass. That being said, the bass presence is still enough powerful to make the sound signature pretty warm. It extends very well into the sub-bass area. The overall sound signature feels, in reality, quite neutral, but analyzing the frequency ranges keeps out some interesting characteristics. For example, the neutrality is an aspect of the midrange too, even though I hear some picks on the upper side. In the midrange area, everything is smoothly reproduced and the instrument separation is one of the best I’ve ever heard. Layering and vocals are incredible, with air and space, body and harmonics. Treble is smooth, not harsh at all, but somewhere sparkly: this gives energy to the sound but may be fatiguing for some after some listening. I personally didn’t get fatigued, though; instead, I felt like I could turn the volume up even too much without hearing distortions or any kind of issues. The mysphere follows the typical reference european tuning, focusing on technicalities and a micro-detailed reproduction, if you are looking for an engaging and bass-oriented headphones, most probably this one will not be for you, the mysphere were meant to sound more on the analytical side, still retaining some warmth to result natural, focusing on upper midrange, treble and airy reproduction.

Conclusions

I wanted to review this pair of headphones because I feel it’s something the community will remember for a long time. Like the K1000, they want to be a benchmark and, in my opinion, they actually got it right. The neutrality is stunning, but the warmness adds that listening comfort that’s typical of dynamic drivers. It’s hard to find something wrong in these headphones: excellent dynamics, wide soundstage, holographic imaging, perfect layering, extreme frequency coverage. I would say it’s hard to recommend something like this for the price, but I’m actually more than convinced about what you get for the money. It’s not your usual headphone, and this just adds value to this product.

PROS:

transient response

speaker-like experience

vocal accuracy and timbre

 

CONS:

resolution could be better at this price range
