Massdrop HD6XX - Could You Make A New Model With The KISS Mod Preinstalled?
more_vert
So Massdrop makes their own HD6XX.
Often times, Massdrop makes their own little adjustments to these custom designs. They've done it with things like the K7XX to great success.
So, there's a mod to the HD650 known to improve the sound (to the ears of most) called the KISS Mod: http://www.superbestaudiofriends.org/index.php?threads/hd650-kiss-mod.3440/
Do you think Massdrop could add this mod preinstalled to the HD6XX?
Maybe we could call it the HD650+, HD6XX+, or HD6XX SE (second edition, or special edition) or something.
Thanks.

Yes, it audible changes the sound (but they'll still sound like a pair of HD 6XX). Biggest change in my experience was the treble region; it's noticeably smoother. I do want to stress that it's a small change and may suffer from expectation bias. It's a simple, cheap mod to do that you can easily reverse if you don't like the results.

For anyone who wants this, it takes about 20 minutes (if you are being extra slow and careful) and about $15 to do yourself, as a once off exercise. Massdrop and Sennheiser don't need to arrange an entire production line for people who want this mod.

Depends. The various tools and items you need are not easy to get outside of the United States, and also the tutorial on SBAF is quite vague in its explanation.
If you could do the mod for me (whereby I send you a HD650/6XX), I'll happily pay you $15 for the work, as well as all fees for parts, shipping, etc.

I'm also outside of the US. Ordered a small kit of Dynamat from Amazon with cheap overseas shipping. The only other item suggested is Creatology foam, and I found something similar at a craft store for maybe $2 a sheet. It's just a 1mm thick bit of generic foam with an adhesive backing. The foam is also completely not required, it's a purely cosmetic touch. The KISS thread on SBAF has pictures in exacting detail. There's even a downloadable PDF of the size of Dynamat rectangles to cut out. If you are unsure about anything, just ask on that forum. Otherwise all you need is an xacto knife and a pair of needle nose pliers, which are available anywhere. Off memory you don't even need a tool to take open the Senns. The $15 reference was just the Dynamat estimate, I assume that you should already have access to an xacto knife and pliers. Seeing as $15 is less than what I spend for lunch every day, I can't see it temping anyone past the hassles of dealing with shipping ;) You seriously cannot screw this up, it is called KISS for a reason. Edit: Fixed a couple of typos.

Massdrop x Sennheiser HE 0X Electrostatic System
Lets make this happen, a baby Orpheus for the modern audiophile world. We have the Sennheiser HE 1, but no other electrostatic from the company for the audiophile that's looking for the Sennheiser sound at an (way more) accesible price. The system should be based on the HE 60 project, an electrostatic with price-consciousness in mind, as the then HE 90 (Orpheus) was too expensive just as the HE 1 is actually. And just like the 600 series it should have a good build quality but using the famous plastic that Sennheiser is known for, which we still have from the 580 Precision and it is still rock solid. And most importantly, great sound quality paired with an energizer that can deliver (more than) enough power to drive the electrostatic driver. I would suggest the name to be HE 0X (Zero X), as it's a baby HE 1 and an 'X' has always trailed on Massdrop x Sennheiser collaborations. I had previously seen that Will from Collaborations said they had already pitched Sennheiser for the HE X0,...

Needing to find new earpads for Momentum (1st version, not the HD1s)
I picked them up for $50. The earpads just arent that great. Any searching only gets me results for the HD1/Momentum 2.0. They seem to be about 2 in x 2 in. On ear of course.

Question for 58X owners..
Do any of y'all go ahead and buy the 6XX after buying the 58X just because you're interested in the differences in the sound? I just bought the 58X but after reading reviews on both, I find myself longing to hear the 6XX as well. Thoughts? Cheers!

Overwhelmed With Finding a Set of Headphones
Hello, I am somewhat new to the world of audio, but have always cared about having good sounding music and media. I am looking for a set of open back headphones primarily for gaming (first person shooters) but also want to be able to listen to music. I listen to a lot of styles from metal to jazz; so I’m looking for a well rounded sound. I don’t listen to hip-hip or electronic music much, so bass isn’t a huge concern for me. I have an old amp/receiver (STR-DH100) and use the 1/4” headphone jack. The amp then plugs into my computer. So my question is... What should I be looking at? I’m around the $200 price range but have wiggle room. I want a removable cable, open back, and comfort is important. I have ATH-m40’s and they kill my ears after long gaming seasons. So far the 6XX and 58X Jubilee look appealing. Also seen some people recommend the Beyerdynamic DT 990 PRO Studio (but it lacks a removable cable) as well as the AKG 7XX. Any input would be incredibly helpful. Thanks in...

Any suggestions for wireless headsets to be worn during exercise that won't fall off
I am looking for wireless headphones with a microphone to be worn in the gym. My ears have an atypical inner ear structure and thus none of the so called IEMs that are 'guaranteed not to fall' work for me. I am looking at preferably bluetooth 5, a hook like design that keeps the buds in place and a microphone that will allow me to answer calls while I am working out. Any suggestions would be appreciated. Budget is around USD 100.

Cheap, budget DAC for the Massdrop x HIFIMAN HE4XX?
As the FX Audio DAC(+amp) X6 sold out, it was well within my budget. Is the O2 AMP + SDAC DAC/AMP better than no DAC for $150? Also what are more budget DAC/AMP combos like this one, and more only-DAC combos like this one. (Cheaper)

Recessed 2 pin connectors
[image] As many of you are probably aware of, the 2 pin sockets on the KZ IEMs are different than those on the TFZ IEMs 🙄. The KZs are smaller and rounded, and the TFZ cables do fit on the KZs, but not great (not the vice versa). I’ve read that the recessed 2 pin cables by 3rd party makers, such as the Tripowin C8, fit the KZs. My question is, do any of you know of any recessed 2 pin cables that fit the TFZs? Or do I just need to use regular 2 pin cables, and let the connection remain exposed?

Over-ear closed back headphone for long flight $200?
Taking a long flight coming up at the end of the month. I am looking for an over-ear headphone that won't disturb who I am sitting next to. I am waiting on the arrival of my 6XX's but have read that they may disturb others sitting next to me. I wanted to start researching some options. Does anyone have a recommendation for around $200? I will be using a XdSd to power them/Dac.
