The new SR-007 Mk2 Open Air Earspeaker has more in common with full range electrostatic speakers than conventional headphones regardless of type.  The goal is to provide deep powerful sound previously unobtainable in electrostatic headphones. STAX engineers developed a unique new electrode structure. Visible through the outer case and gold plated on the outer edge, this new electrode has no holes and thus provides an increased diaphragm vibration area for rich, deep bass sound yet retaining all the delicacy and finesse STAX is famous for.

Rigid Metal Housings

To maintain clean, distortion-free sound, it is most important that nothing other than the diaphragm should vibrate. Within the STAX SR-007 MkII the stator assembly is encased in a thick insulated resin case firmly fixed to the rigid body. The results are nothing short of spectacular. No vibration, no resonance, just music.


Utmost comfort for maximum enjoyment of your STAX SR-007 MII is provided with earpads that are fully adjustable to the shape of your head that are made of genuine ultra comfortable sheep skin.

    For electrostatic headphones, Stax is the only game in town. On your computer will get you (in my opinion) a system that cannot be matched by a dynamic headphone setup. Bach911, Audiophile Consumer, June 2014

    Definitely the best value Hi-Fi headphone out there. I know what you’re thinking, but by “value” I am of course comparing it to every other headphone in its price range and also above its price range. More than a few people find the SR-007 to be the greatest headphone ever made, and here it is for less than half the price of the new Audeze LCD-4, and almost half the price of the HiFiMan HE1000.

    And how does the SR-007A compare to those, you may ask? I haven’t heard the LCD-4, although I have listened to the HE1000 extensively on a high end system. Simply put, no dynamic or planar magnetic headphone can compete with the SR-007 or SR-009 in terms of transparency or detail. These are inherent benefits to electrostatic technology, especially the transparency, which is best defined as clarity or having less interference between you and the music. Transparency equals realism, and combined with excellent performance in almost all other areas, the only headphone I can honestly recommend in a similar or higher price point is the SR-009.

    The SR-007A is wonderfully transparent with very realistic decay (also far beyond what non-electrostats can deliver), amazing detail, a very well rounded mid range, surprisingly good bass performance, and it isn’t as veiled or relaxed as you might think. As far as bass goes, the SR-007A sounds almost subwoofer-like compared to Mid-Fi dynamic headphones like the AKG K7xx and Beyerdynamic DT 880 Pro which I’ve owned previously (the K7xx I still own). This headphone does have a bass port, accentuating mid-bass response and sacrificing extension somewhat, but the SR-007A is only bested by very few with regard to bass extension (the best planars and the SR-009).

    The treble shouldn’t be harsh or fatiguing for anyone. It does sound somewhat veiled, but it doesn’t make for an overall relaxed sound characteristic like I was led to believe. This is probably because the current production SR-007’s (from March 2015 and onward it seems) are said to have more treble energy than the previous SR-007 models.

    Sound stage and imaging are also excellent. The sound stage is wide, deep, tall, and noticeably three dimensional unlike most headphones. The AKG K7xx and its siblings are known for having an incredible sound stage presentation, but the SR-007A is bigger in every dimension and more well defined in every dimension. The imaging allows me to pinpoint where every sound is coming from (especially in a good recording), giving every instrument and sound its own defined space with no overlapping and perfect separation.

    This headphone is also supremely comfortable thanks to the soft genuine leather suspension headband design (which doesn’t put too much pressure on a small point on your head like others do), and the very large and extremely thick lambskin leather ear pads. The pads totally engulf my ears just like other higher end headphones, and unlike many of the Mid-Fi offerings. Combined with the thickness and how soft they are, and the suspension headband, it floats on your head and is one of the most comfortable headphones around. The suspension headband auto adjusts and will fit most sizes.

    I’ve heard many of the top headphones like the HE1000 (extensively), HE-6, LCD-3F, Sennheiser HD 800, SR-009. The only one I can recommend in addition to the SR-007 is the SR-009. I would love to spend more time with the SR-009, maybe one day. The SR-007A does leave me wanting a bit more treble extension and less “veil” without making any sacrifices and the SR-009 may provide that. Rhamnetin, Audiophile Consumer, Sept 2016
