Follow along as I make a volume knob for my Sony MDR 7506s, and mod the headphones to have a detachable cable.
⭐Headphone modification service⭐: If you would prefer the modification to be done for you, I am happy to perform the mod myself. Email "business@hardwareunknown.com" to get started.
After I started making RU-vid videos, a friend of mine asked me to film his video course on how to use a laser cutter. I realized quickly that my music headphones were not ideal for monitoring sound on set. I did some research and found that 7506s are hugely popular in the audio world, as they are purpose-built monitoring headphones. After having them for a single film session, I loved the quality but disliked the permanent cable. On top of that, the lack of a volume control was aggravating my tinnitus.
I wasn't going to settle for these shortfalls, and I set out to void my headphone warranty. I successfully did that, and also was able to keep them functional. Now they're my own unique pair and exactly the headphones I want.
Originally this video was meant to be a bit of entertaining, educational inspiration for you and your projects, like my previous videos. As I was editing it, however, I realized I had enough footage to make it more of a step-by-step guide that you can actually follow to upgrade your own headphones. If you do so, enjoy my mistakes, take your time, and don't worry. They're just headphones. If you break them, you can get another pair. Learning and gaining confidence in how to change your world is worth it one hundred times over.

I love voiding warranties, although in truth most of the stuff I mod is long since out of warranty. Great explanation and demo here.

@HardwareUnknown 2 года назад

It's fun isn't it? But hey, if it's out of warranty it can be nice since there's no worries at that point. Sure you can damage it but you can get another if needed, and you learn so much along the way. Glad you enjoyed!

The holder thing is awesome. And respect for using heat shrink on everything. Im in the process of searching out clear so I can make uv reactive color coding. Im getting a bunch of nice elbow jacks from a place called Thomann in Germany. I figure for the price of buying the DT770 with the detachable cable I can stock up on a lifetime supply of high quality headphone cable , jacks and elbow jacks. That way I can fix all the earbuds I have in the junk drawer too.

@_c_y_p_3 5 месяцев назад

I started using the under layer of cool colors and designs when building tattoo machines, often clear heat shrink tube is used over simple paper, money, stickers etc…. i figure the same can be done with headphones and studio cables. Say a few neon stripes , enough to make each cable stand out individually….

@HardwareUnknown 5 месяцев назад

That sounds really cool. Would love to get my hands on some clear heatshrink. I wouldn't do an electronics project without it. Particularly in such cramped quarters, the chance for a short is too high. I like doing things right way, so that when I seal everything up I know it will last for a long long time. No potential loss of stickiness and unwinding like tape if it gets hot. A few times I've been joining together such a rats nest of wires that I incorrectly count how many pieces I need, that's always fun to go back and fix. XD Well worth it though. Definitely sounds like you could pull off what you describe with headphone cable. What's the deal with the UV reactive color coding? That sounds interesting. What are you going with UV reactive for? Is it for raves/venues that use black lights?

@nightwavesz5212 2 года назад

Does this change the quality sound?? Or it’s volume?? Great video!!

@HardwareUnknown 2 года назад

Thank you! While I'm not an audiophile with a trained ear, I have not noticed the quality or volume changing (other than as intended when using the knob). If the soldering is done poorly it could become loose and possibly cause crackling, but apart from that it should be no problem with basic soldering skills. Plus, you can redo the solder joint if needed.

@subarusensei3685 2 года назад

What I love when Sony made the 7506. Is that they knew this was going to a market were modification are comon on gear so they have a wiring guide in the box. Also Sony does provide spare parts from what I’ve heard.

@HardwareUnknown 2 года назад

They also have a fantastic exploded view of all the parts included with an insert in the packaging. Every part is labeled in case you need to replace them. I have to hand it Sony, they did a solid job with these especially for the price.

@subarusensei3685 2 года назад

Yep that too. I also have seen a company (remote audio) use a 5 pin mini xlr to have a locking detach cable that has a microphone for production things. So I am probably going to mod mine to that.

@HardwareUnknown 2 года назад

Now that's cool. Best of luck with the mod! Making stuff your own, especially functional changes like that, is so rewarding.

I use them all the time whenever I'm video editing. Holding up great so far! Only thing I would have done differently is double sided tape the volume button to my desk earlier. I left it loose for a while, and some time back I taped it down and now I use it all the time since it's so convenient (didn't want to screw into the top side of my desk).

SHOUTOUT RIGHT TO REPAIR

@HardwareUnknown Год назад

The right to repair should have always existed and been protected from the beginning. It's our stuff, it saves resources, it teaches valuable skills, and so much more. The only thing it doesn't save is corporate profits. Too bad. Right to repair all the way.

the nub is there to lock the pot so that it doesn't spin the housing.

Thinking of doing this but kinda scared

@HardwareUnknown 3 года назад

It's a bit nerve-wracking modifying perfectly good stuff like this that you've paid good money for. Here's the thing, the disassembly and drilling is pretty straightforward. The part that takes some care is the soldering. To get some practice first before doing the actual headphones, buy a cheap auxiliary headphone cable or find an old one, get some 3.5mm replacement jacks, cut the cable somewhere, and practice soldering the jacks on. When you feel confident, then you can move onto the headphones themselves. When you switch to them, practice a bit on the cable end you cut off first just to make sure it behaves the same as the first one. Doing things in stages is the way to go to build your skills. You got this! Let me know if you have any questions along the way.

@@HardwareUnknown is it ok if I don't have the dremel tool

@HardwareUnknown 3 года назад

Yes. A dremel makes it easier as a rotating bit can help you carve small amounts of material away, but you can also use extra pressure on the side of a drill bit, a small file, or even a utility knife in cases where the material is soft like plastic (aim the blade away from your fingers and be careful it doesn't slip). For this situation (since it's metal) I'd go with a drill bit for the initial hole and to widen it most of the way, then a small round file like the one in this set to deburr/smooth the edges: amzn.to/3devu1F

Warranties are overrated.

@HardwareUnknown 2 года назад

They totally are. Like what... you get a company to MAYBE replace a minor part while charging you exorbitant service fees? Or you can go against the warranty and make things suite your own unique needs. I'll take the latter.

@hebinyao709 2 года назад

@@HardwareUnknown As long as we take good care of our stuff, the probability for them to go wrong within warranty period is very low. I personally never care about warranties for cheaper or easy-to-fix products.

@HardwareUnknown 2 года назад

Exactly. As a kid I used to fret about voiding warranties even with cheap things. Then I realized it prevents you from learning a massive amount. Now, I'll buy things with the express purpose of immediately cutting into them. Feels great to make things yours.
