Review: An excellent value if you catch them at the right time - The ESP-950s are very nice electrostatic headphones, and if you can get them for hundreds off of the $1K manufacturer's suggested price, as I did, they are a great value. Pros: They sound great. Very accurate from bass through the mid-range, with an emphasis on mids. The bass is excellent, but not overdone -- these aren't for bass heads. They love human voices, guitars and pianos. They are lightweight. They come with their own amplifier (you have to use it, or a Stax amp with a modified cable). The whole rig is "portable" in the sense that you can run the amp off of batteries, but it won't fit in your pocket, so I would classify it more as "movable" from room to room, and flexible because you can drive it from an MP 3 as well as any source outputting analog via RCA jacks. Koss puts a lifetime warranty on the system. Cons: They are made of plastic and the earpads are "pleather" or naugahyde, or whatever you wish to call fake leather. Not really uncomfortable, but they do get a bit warm, and for the price a nicer material could have been used. The volume control is dual, i.e., separate for left and right channels. This allows precision tweaking of the left-right balance, but it is also a pain in the rear if you just reach over to tweak the volume and you end up changing the balance because you didn't turn both the inner and outer rings the same amount. And you will change the volume a lot with these headphones, because they have a relatively narrow "sweet spot". They need to be driven a bit to hear all of their capabilities (like most quality speakers and headphones), but they do not like to be over-driven. Pro and Con: They are very revealing. This is a good thing, in that they reveal everything good about a recording and the source of the analog signal received by the amp. They also reveal everything bad about the recording and source, and since much of today's music is poorly recorded, and MP3s at low-mid bit rates make poor recordings even worse, much of the material that many of us listen to does not sound very good on these headphones. It isn't really fair to blame the headphones, but they are a bit more unforgiving than many headphones out there. If you listen exclusively to low-res MP3s of modern pop/rock, you will probably not be overly happy with the ESP-950s. But if you listen to CD's or SACDs or high quality, high-bit-rate digital recordings played through a quality DAC, you will enjoy these headphones.
Review: Now that I've heard one that clearly works properly... - It's actually not bright or strident at all. Very midrange-oriented. Very smooth. A perfect balance between not-too-dry and not-too-liquid. Just right in that quality. Extreme highs & lows are rolled off and the bass lacks kick, but it's a pleasant, forgiving, pretty even tone in between that is essentially free of artifacts in the mids and highs. Exceptionally refined and delicate. It does require very lean, detailed digital recordings & a great source to shine its best. Mine direct from desertcart, though, has a slight ground hum issue on the right channel even when no power is connected to it, though when it is connected to an audio source it's even worse. It's faint, but noticeable to me on quiet passages. It goes away completely when I touch anything metal on the unit, such as the front of the 3.5mm jack. So putting an unused 3.5mm cable in there and the other end in my waist band is a temporary solution to grounding the unit or preventing it from acting as a radio pickup. .. Or whatever it's doing. I'm not sure which is occurring on it, the non-grounding or radio pick up. Apparently, issues with the energizer/amp are common and people frequently have to send the ESP for replacement or repair. Luckily Koss has their truly perfect warranty... except for maybe the fact you have to pay for shipping both ways. For kids with perfect hearing, who are not bass-heads (or even too particular on just bass tightness, regardless of volume), and who plan on taking care of their ears (read that: keeping the volume down low and wearing musicians earplugs whenever in a loud environment), this might be the be-all, end-all of headphones. If you need a little more low-end kick & tightness or extension up top, then you may want to look elsewhere. If I'd bought this as a youth, not gotten into beat-driven electronic music, and taken care with my hearing, this would be the one.

### ⭐⭐⭐⭐⭐ Koss’ finest headphone, delivers a personal concert.
*by J***. on April 10, 2026*

Set comes in a very nice leather case, that holds everything and a cd player very well. Feels well made despite so light. Hooks up easy, and sounds excellent. Bass can go surprisingly low, mids clear, treble is sparkly but not harsh or sibilant. However like most high end headphones these display what music you feed in. Badly recorded tracks or using a meh source and these will not cover up or temper the sound, what goes in is fully reproduced as it is. High quality tracks fed in from a high quality source will sound heavenly. Soundstage can go 3d wide, or intimately closed in depending on the song/source/ preamp. Split volume control allows very fine tuning of the headspace. Very light on the head. These are open back. Sound and noise can come in, and everyone near you will hear what you’re listening to.
