What we are going to be up to in 2024 

++1 on Edition XS mods Jason. I'm following you closely bud. Great job so far!

If anyone deserves ongoing success it’s you guys and girls. Super talented bunch. Have a great 2024!

i would for sure buy whatever mods you make for sundara closed backs

I'm super excited since I just got the Edition XS, probs gonna grab the headband mod since I've been having a dickens of a time not crushing my skull with these

Love the Mug of Tea, keep up the good work.

Best of luck in coming year! 🎉 i was wondering if you will restock foam mod kit for Sundara closed back, since you are going to work on those more.

I’m on my second pair of custom cans in 10 years. Both sets have been absolutely incredible. You guys deserve all the success! Wish you a very happy new year

Welcome back! Great to hear that the business is running.

Happy to hear the biz is good

Modular headphones! Now that is an interesting idea!

Nice to see things are going really well. Very proud of you xxx❤

Hi folks, I like your work. I found the modifications to the Sundara closed back very interesting. Now I own an OLLO Audio S4X and am thinking about buying the S5X too. I would be happy if you would discuss the two headphones and also if you had a few suggestions for possible modifications. Happy holidays and all the best! Frederic

I’m so pleased with my Sundara CB now that I’ve installed your mod. I’d be interested to know whether adding any mass to the wooden cups would make any positive differences, as they’re a bit thin.

Looking forward to seeing what else youre able to do with the sundara closed back. The foam inserts were great, and the pad adapter ring has been useful so far.

Me trying to see how your ultimate cable look like when worn outside feels like getting a shot of a monster in a steven spielberg movie with a lot of suspense and tease. In your original video, the cable is mostly on the table but at no time it is on a set and on your head. Then there is that guy who reviews your mod that has that cable as well, but he never put it on and here I see it hoocked to that hifiman lol New to the hobby but you are already my favorite guy :) I dont want to use more than 100 on a cable, but that ultimate cable project is really cool and I wouldnt mind. I think the black and white will fit perfeclty my audeze LCD-xc (21) but really dont wanna feel like wearing a belt around. Located in norway so I often have a jacket

Completely awesome. I have some He560 V1's I'll be wanting modded by you guys next year.

iam so curious about the Edition XS stuff coming up in 2024! The headstrap is a real gamechanger for me, love the extra comfort! You guys have developed some great products

How about taking a look at the Fiio/ Jade Audio JT1’s, it’s a decent set for £65 but I’m sure you can turn it into something special 👍

plz mod Philips shp 9500, its a great openback headphone but seriously lacks bass

Very interested in those build it yourself headphones!

Glad that business is good, I hear the excitement in your voice! Have you ever done any T50RP mods? I appreciate that it might have been done to death but I'm happy with your DT770 V3 and have a pair of T50RP to mess around with.

Hi, Jason! Can DT770 damping pads reduce 200-300 Hz bump on the Sundara closed? It seems that it is a wood cup resonance. Also, I noticed a sound improvement with better cable. Going to test DIY silver plated cable.

Sooo HFM doesn't sells drivers as spare parts like Senn? Cuz that would be a huge money saving when you are doing such projects, why not just buy drivers and have one spare of headphones, than buying bunch of them :D

Interesting stuff. I dabble here and there with modding, well i did, but i don't have a measurement rig as of yet, I'm purely relying on my ears. It is more of an experimental past time, to satisy my curioisity. I've messed around with the Creative Aurvana Live, but i ended up stripping back the mods because i lost track of where i was up too. I mostly tinkered with IEMs though. Since moving about three years ago, i haven't kept it up. I am by no means an expert, and i had an habit of not keeping notes. Will be interesting to see what you do with your future projects.

Awesome! What is the link for the 400se along with the headphone strap and cable mod? Happy Holidays

please find a way to make DT770/990 Pro wireless :P i am thinking about modding mine and add a 3.5 jack and then use something like Lekato monitoring receiver and transmitter on my laptop but there has to be a better solution..

Quick question for you, I have the hd-25’s for dj’ing, I like to have the right ear cup pivoted back, but the left side pivots can I change it over??

I recieved the thicker leather strap two days ago. The quality is nice but after 3-4 hours the strap streches so much with my Deva Pro that the uncomfy bit in the middle hits my head again. I redid the sticky bits on both sides ca. half a centimeter upwards today but after another 3-5 hours it streched again to that annoying point. Can you give me any advice? i have around 5mm on either side left and will try tomorrow.

Hi. I noticed that the Sennheiser 600-series mass-loading kits seem to be removed from your site for the time being. Are they out of stock for the time being or discontinued? Just ordered a pair of HD600s today.

Buddy, could you speak normally as a human being? Only your friends probably understand you, or is this video just for them?
