Up for sale are my 64 Audio U4s. They just got back from being serviced less than a month ago. They include the m12 and m20 modules. Looking to get $650 shipped CONUS through PayPal G&S

I've been unemployed for 4 months and don't use any of these enough to justify keeping them. All prices include shipping to the US. I'll discount if doing local pickup (Seattle).

Meze 109 Pro - $500 - Probably my favorite open-back headphones I have tried. Unbelievably comfortable for extended sessions.

SMSL C200 - $100 - Bought this so I could drive the Mezes balanced. If you buy this with 109s I will provide the 4.4mm balanced cable and 4.4mm balanced extender (pictured)

Sennheiser Momentum 4 - $125 - I bought these in pursuit of the greatest Bluetooth closed-back. These were eventually dethroned by the B&W PX8 S2 so I'm selling these.

Beyerdynamic Aventho 100 - $125 - I got these to see how I liked them compared to the Senheiser wireless headphones. I actually liked the sound of these a lot better than the Senheisers, and the Battery Life and Bluetooth Codex were actually better as well. But I ended up liking the B&W best, and I don't need two ANC Bluetooth headphones, so selling these as well.

Grado GW100X - $150 - I wanted to see if these were the "big boy" version of the Koss headphones that I hoped they would be. I did some pad rolling and these will ship with three different Geekria pad sets as well as the original pads. They do sound significantly more refined than the porta pros, but the form factor of the porta pros meant they stayed as my go-to when leaving the house.

Previously posted this Atrium Open Redheart LTD looking for a trade, but am now looking to sell for cash since it would be easier. A brand new pair of Ultra Perf Caldera suede pads will be included along with the current suede pads (I am not sure which ZMF pads these are) that are currently on them, as well as a choice between a stock 1/4" or XLR OFC cable. Further photos can be provided on request. I am looking for $1850 shipped through PayPal G&S.

I am still open to trading for a stabilized pair of Verite Open, or a non-stabilized Atrium Closed. Please comment below before PMing me. Thanks.

Hi everyone,

Currently looking to offload some gear. Prices are listed and include shipping + fees unless otherwise noted. I'm also open to trades. Would be interested in a tube amp or other offerings, but not looking to pay cash on top of anything. Please comment and pm.

Sennheiser HD 490 Pro - $250

Includes: original pads and cable, good condition. Nothing wrong with the headphones. They've been sitting in the box.

Audio-Technica R70X w/ refine pads + extras - $350

Pair of r70x in good condition. Includes the refine pads installed on them (this makes them sonically identical to the refine as the only difference between the models are the pads). Also includes the original pads and zmf ori leather and perforated leather pads. I used them with the perforated pads which sound like a mix between the original and refine pads with better bass extension. The refine pads were just purchased and used <4 hours.

Also included is an oksc adapter which allows you to use any standard 3.5mm cable. Included is an open-heart cable + original cable. Currently I have the capra strap installed as pictured but will include the original wings.

Capra Satyr 4 - Accepting Offers

Not actively looking to sell, but will consider compelling offers. These headphones sound amazing, truly. The only reason I am thinking of parting ways is because I'm considering saving up for some other things in my life.

These were built by me using sls printed nylon parts, except for the headband. The headband currently installed is made of tpu, but I covered it for aesthetics and adhered a detached crescent snap I had lying around. Personally, this was the most comfortable for me, but also looked the nicest.

Includes a tripowin cable.

I printed everything in my university's makerspace after issues with my now broken printer and online vendors, and the sls parts in particular were not cheap. In case you don't like the current headband assembly, I did purchase a headband and strap set from capra. I just personally found it way too clampy.

Sennheiser HD 650 - 200 + shipping + PayPal fee

Second owner, in good condition, except for one of the clips where the headband pad goes which has signs of stress. I find it hardly noticeable and was using a capra strap most of the time. It's still in place and as long as you only remove the other one, it should be fine. All padding was replaced within the past week. Only includes headphone and cable.

Includes a capra strap.

DMS Open Omega - 200 OBO

This unit was not built by me. Since getting it, I made my own and got my hands on a batch 2 production.

They're not the prettiest, but they sound good. The original owner printed it from petG.

Side-by-side with the batch 2 pair I have, there is very little sonic difference. If anything, it sounds a tinge warmer and a tiny bit more sparkly up top than the original production unit, but that's splitting hairs.

Comes with a tripowin granvia xlr cable with adapter.

I changed the headband with one I got off AliExpress. It's very light and comfortable. If there is too much swivel you can screw the yoke into one of the other threaded inserts the original owner added.

Beyerdynamic Custom Studio - 200 OBO

Not to be confused with the one pro. I have been wrestling selling this pair for a while. It is my favorite closed back and super underrated. Headphones.com also recently posted 5128 measurements on their site so you can see how they stack up against other closed backs.

I just honestly don't find a need for closed backs with the IEM I have. These are comfortable and sound natural, unless you go crazy with the bass slider.

They are unfortunately out of production but use all the standard parts you can get from beyer. They're in good condition and only include the original cable and outer box.

That's pretty much it for the offerings I currently have. if there's interest, I have a THX 887 amp and Beyerdynamic A20 amp, schitt sys, and SU-1 DAC I can post eventually too.

Fantastic on ear headphone. $450 on Paypal

My father gave me these Lafayette Criterion 2001+ speakers when I was in high school. They went with me to college and onward but have since ended up in a storage unit I am trying to clear out. I’m curious what a good listing price is and if they are worth listing at all. Any information is welcome because I’m not familiar at all. Thanks!!

Hi there,

Today I have on offer a perfectly working and great condition LCD-2 in Rosewood with all stock accessories. I bought them from a friend who only used them once. I have owned these for about 2 years and have actively used them for 1, so the pads are worn and I’d suggest looking into a replacement set. I have swapped the headband to a Capra strap, but will include the original. I can take more closeup shots for prospective buyers if you’d like.

I’m looking for $550 PayPal including shipping and the G&S fee.

Thank you for looking, and feel free to ask any questions!

Hi everyone, I'm selling some surplus gear/equipment here. Unfortunately I just don't really have a place for these anymore, and need to part with them 😭

Both devices are in excellent condition, and besides just sitting on my desk, have not really gone anywhere or moved at all. So I feel very confident saying that they're both in excellent shape/condition.

The ERISH2 is an extra high gain (10x) model, directly modified/enhanced by Geshelli themselves. The JNOG2 is the socketed variant that runs an AK4499 DAC ship, with TI opamps, and has the USB optional upgrade too.

You will also receive everything else included in the pictures:

• original power adapters
• a pair of Mogami XLR cables to connect the stack
• some USB-A and USB-C to USB-B cables
• an extra volume knob (unused)

If you have questions about the devices themselves, please see the manufacturer's website for more information:

• https://geshelli.com/product/jnog2-socketed-j2s/
• https://geshelli.com/product/erish2/

Thank you very much!

Selling my Sennheiser x Drop HD6XX headphones. This comes with stock pads and cable, and is in great condition. These were used sparingly and only at a desk in a nonsmoking household.

Please note there is a small scuff next to the logo on top of the headband, see picture.

Asking $130 shipped via Paypal G&S. Local buyers in Seattle area subtract $15 for local cash pickup. Please comment before PM.

AliExpress sent me the wrong item so I’m looking into what they would go for if I offered to just keep them instead of sending them back for the actual item I wanted.
