I got my pair 3 days ago and will share some brief impressions after 5-6 hours of listening time. Firstly the build quality on these is insanely good. I have never been able to personally justify owning super expensive cans but holding these in your hands and wearing them on your head feels like a million bucks, they feel 'solid' and attention to detail is high. I got a lot of compliments on the looks already On sound, this is my first experience with the 50mm Peerless driver, I can see why it's popular. The driver has good sensitivity and performs in most areas with no obvious weaknesses. Tomislav's approach to acoustic design seems to make everything as inert and rigid as possible to allow the driver to speak for itself. This leads to a modern and matter-of-fact sound. The v3 would make really good open-back monitors, with a lack of ringing or smearing at any frequency. The tuning reminds me of early Beyers, with the small 3khz dip and early bass roll-off. The upper mid tuning shaves off a bit of bite without necessarily recessing anything. I listen primarily to indie and alternative rock so my general preference is the opposite of this, which is why I use HD600s most of the time. After reading Marv's initial impressions I asked Tomislav to tune my pair to be a little warmer/rounder in the bass. The roundness of bass transients on my pair is similar to HD650 though less in amplitude and extension. It's just shy in extension of what I would like for electronica and pop but fine for mostly everything else. Resolution is in line with what I would expect for this price point. Again, they remind me a lot of Beyer cans from the early 2000s but without the dirtiness and treble ringing. I guess this makes sense as Tomislav states the T1 is one of his references. Overall these are mostly-neutral and very comfortable headphones that are definitely worth their asking price. It's really hard to believe this is being done by a one-man shop, and I wonder what lead times will look like when more people learn about these. A few years ago when I wore headphones for several hours a day I would've killed to had something like these. Today, I only wear headphones for serious sit-down listening two or three times a week, and I will continue to reach for my (vintage) HD600s. I also have the LTS v1 but haven't listened to it enough yet to give any impressions.
