    Hi everyone,

    First of all thanks to @ChaChaRealSmooth for giving the go-ahead to post here!

    Most may already know- I’m Jupiter, and I’m the guy currently making the HD650 and HD600 mods that are known as the JAR650 and JAR600. JAR is for Jupiter Audio Research, and honestly it’s more of an in-house name than anything else. Half serious, half frivolous! (Honestly I think I’m still far from Industry.)

    I started making the prototypes around 2017 and along the way so many people have pitched in and helped me out that I wouldn’t want to call the headphones my own work/creation. Definitely it would have not been possible without the kind souls I’ve met in this community, and also the incisive criticism from those much skilled than me. (You know who you are!)

    When the design got finalized there was a loaner tour and I was really happy that people recognized the hard work everyone put into this. It was really great, until starting in 2020 I’ve not been able to make practically any because of the COVID situation and on top of that, mandatory military service.

    Now though, it looks like the situation has gotten better (in where I am, anyway) so I can now make a few pairs (albeit in a much lower capacity than before). It’s moreso that I just think it would be great if people who want to hear this thing can hear it, instead of me trying to sell more pairs. (Despite how much fun making each pair is, it’s really exhaustive and it’s not something I want to be doing all the time! Last year I was doing this on top of a ton of exams and that honestly had made me really stressed about having to make these.)

    So depending on the interest Chacha has kindly said a loaner tour can be made. And also I just wanted to take this time to write this thread so that I can stop being a mystery man and help out if anyone has questions for me.

    Thanks!

    Congrat for having a dedicated space in this forum. Not to mention I want to get my hands on your products (I'm very much in), I also would like to read your in-depth thoughts/insights regarding design, voicing, and modding anytime in the future.

    Finally, the man surfaces \/! I was an early adopter of the JAR HD 650 that I held onto until a week ago. A person that was introduced to me listened to the JAR 650 and the 2A3 tube amp I used to pair it up with; he bought the HP first and the tube amp a couple of days later.

    I should be contacting him soon on a JAR 600 (the 600 is my preferred HP in the Sennheiser line). Welcome aboard !

    Welcome and glad things are looking better on your end! I’m very interested in one of your headphones, is there a pricing structure in place?

    I'm glad you're back and safe, I'm absolutely still in for the 650's regardless of the time line.

    As a treble-allergic basshead, I actually LIKED the JAR600 when I borrowed it from brencho. Kudos to anyone who can make a headphone that's impossibly both smooth and hot in the top half at the same time. That was a really tight and lively phone. I imagine the JAR650 would be even more up my alley.

    I'm going down my own path with modding the Senns (and I'm probably aiming for a different target than what's here) but the JAR mods are improvements across the board vs stock with zero drawbacks. Nice work and cheers to your future success.

    Sorry for late replies!! I only get to use internet 3 hrs per day here..

    Thanks! I’m happy to answer any questions you might have on that- although I’m not an expert still! There are still better mod wizards here than me, I just happened to stumble on something that looks clean and works well, and people here helped me improve that.

    I first made this thing for myself. I also loved the stock 650 but I couldn’t understand how it could do so many things right, but screw up on some parts. I made a prototype full of really sloppy damping materials as a proof of concept first- I first wanted to get the target damping areas right first. Then I thought it would be pretty if I had some kind of enclosure helping and containing the damping. So next I spent many nights drawing this up on Solidworks, I had to learn how to use that thing for the first time. I wasn’t talented, just really stupidly stubborn enough.

    Getting the enclosure to fit perfectly took some months, and finding the right damping material that would be durable for long term use also took some months. Once something somewhat presentable was made, I showed @Jinxy245 what I’ve got and sent it to him for fun. Cool stuff happened after that- @Pharmaboy came over to Jinxy’s and liked what I had made. Some months later I actually came over to NY to meet them. Their thoughts really helped me out, since there were no ears I could trust where I was. But more importantly their encouragement really meant a lot to me. I was happy that others liked what I had made at first for myself. So definitely this was not just me, and I have a lot to be thankful for!

    (I can continue if you want, about how I was lucky enough for @Hands to give me specific guidance and much more advice outside of that, and how it eventually led to a loaner tour)

    Voicing- well my goal was to fix the problem, but I ended up fixing it and (from what people have been telling me) improve the rest. I first started to do tuning using the songs I like, because I simply didn’t like how the stock voiced some songs and my initial motivation was to fix that. Then after Hands got me measurements (yay!) I started to have a second point of reference. I don’t have a rig yet- that’s still too expensive for me! It would be really nice if I could do some QC using the rig though..

    Hey Koth! Yep I know you were one of the first people part of the initial impressions. I was really encouraged to improve on the design after how much you enjoyed it and your thoughts on the sound. I am also pairing my own JAR650 on the tube ECP T4- thanks for the warm welcome!

    @tommytakis @Brian D @RatSalad I’ve always been thankful for all the thoughts and the encouragement! It’s still really wild for me to see people enjoying what I initially started but eventually something that we’ve been able to make as a community. That sort of encouragement is what really pushed me to make each pair with effort and care in the middle of all other life things going on, as well as the help others had given me- which they also took out of their time among all the life things. I like that everyone involved took time out of their life to do something that we liked doing. It’s what really captures the spirit, IMO.

    Thanks! I was actually reading your impressions with much interest along the time, especially with that TH900 stuff as well. And your own work on the 600. Really interesting stuff- I need to try so many things once I’m outta military. I’d love to hear your work if I get the chance. Let me know if you need anything from me as well. Cheers to Senn modding!!
