Awesome, thanks for that review, I've been curious about these since the original announcement post. Do you have any experience with the Massdrop TH-X00 or Fostex TH-610/900/909? The Massdrop x Fostex TH-X00 Ebonies are my current quality and quantity bass champs, I wonder how these stack up.

Also, where can you buy them? I can't seem to find them for sale anywhere, is there an official launch date pending?

HT: Sony 940C, Oppo 203, Harman/Kardon DPR1001, Infinity Interlude IL40 x2, Infinity Interlude IL36C, Infinity MS-1 ii x2, Infinity MSW-1
Computer: Elac Uni-Fi UB5 x2, Elac Element EA101EQ integrated amp, SVS SB-12NSD
Dedicated 2-channel: Infinity Intermezzo 4.1t towers, Bluesound Node 2, Emotiva PT-100, Crown XLS 1502, Furman PL-8C

I have not tried those but I have the (I believe similar) E-MU Teak. Did not think to do a direct comparison because closed vs. open-back.

The Ultimate Ones should have live retail links available this week. World Wide Stereo, Crutchfield. Word is the shipment from the factory just arrived, it's a matter of making the inventory available/live on websites. I'll post links when it happens.

Is it just me or do these not look EXACTLY like the Sivga SV007 headphones for $80? It could just be a coincidence, or it could be different drivers in the same earcups, or the Sivga could be the buy of the century, but something seems fishy to me.

This discussion already occurred when they were released. They look alike because they are based on the same platform. Yes, different drivers, also different materials like lambskin. So no, KLH did not spend money creating a whole new production line, it concentrated on the driver itself and used a already affordable, well-designed platform to accomplish this. This is the path to getting beryllium driver headphones for 300 bucks. Anyhow, long story short is it's not just you, but the "what and why" of it is reasonable not fishy.

I didn't realize this was already discussed. Both the KLH and the Sivga are beautiful headphones.

No problem, that article was posted about five months ago. Here's the statement I got from KLH:

"The KLH Audio Ultimate One Open-Air Dynamic Headphones are as much of a statement as they are a solution. This is a $300 pair of headphones vs. sub-$100 (SIVGA). While I’m sure the SIVGA sound good, the KLH are much more advanced in sound and comfort. KLH wants these to be the headphones you keep forever.

The ear cups of the KLH Ultimate One are solid ebony wood (and legally harvested to boot!). Not only do they look awesome, but according to KLH Audio Chief Technology Officer Steven Howell, the extremely hard construction of ebony wood goes a long way in eliminating / reducing resonances.

The KLH earpads and headbands are much higher-quality than the SIVGA too.

KLH opted to use Sheepskin in any areas that come in contact with the skin (or scalp). This is because sheepskin doesn’t distress from human oils.

The company also opted to use premium grade cow leather on the areas subject to sunlight – namely the outer edges of the ear pads and headbands. The cow leather ages very nicely. In contrast, the SIVGA uses polyurethane.

The foam in the KLH ear pad is more advanced too. SIVGA uses a single stage, where KLH uses a dual stage: its outer round is a softer more pliable cushion, and its inside is stiffer. This is less resistant to collapse or compression, meaning better fit, and longevity.

The actual air cups of the KLH are 10mm bigger in diameter than SIVGA, and there are substantial driver differences too. The SIVGA uses a dusted diaphragm design, i.e. dusted with beryllium where the KLH driver is 1) higher beryllium content and 2) has a more advanced coil (32-ohm) with higher-current capability than SIVGA. This makes the driver faster, more compliant, not as brittle sounding.

The input cable to the KLH headphone is a Silver Litz cable, where SIVGA is not."

Any other headphones you could compare these to for sound quality? Would they compete with Focal elear or Audio-Technica MSR7?
