Question about Sony MDR-7506 Professional Headphones

1 Answer

Need to repair jack end of cable.

I need to resolder a connection on the jack end. Getting a new set of cans ain't in the cards...fixed incomes suck. These are the only cans that have ever suited me, and I've tried a lot of them in 20+ years. Failing a way to defeat the press fit (which is likely the case), I'm gonna need a part number and a road map. Thanks.

You'll need an 1/8" male phono plug, also called a trs plug, a soldering iron, and solder. you can get this stuff at a place like mouser. don't buy any junk from radio shack. the soldering irons are ****, the solder is **** and often won't make a good connection, and their phono plugs are the cheapest of cheap at high prices. if you don't know how to solder already, i wouldn't recommend taking your first shot at soldering on your headphones. practice soldering some small wire first. the wire used in the sony headphones has a transparent coating of lacquer or teflon which will need to be scraped off with a knife or burned off with a lighter. remove just enough to make your solder connections and no more, maybe 1/8". the bare ends should be clean before soldering. a headphone plug has a tip, ring, and sleeve, in that order. the tip is left +, the ring is right +, and the sleeve is a common -. i don't know what color wires are in your headphones but i'm betting there's a blue, red, and a bare copper. the blue would be left, red right, and bare copper would be common. the contacts of the replacement plug in relationship to tip, ring, sleeve should become obvious with a close look. if it's not obvious, a multi meter set to continuity would help. good luck

Jbl roxy over ear headphones ref 430 need to install new cord. how do i open cans?


Hello.
Headphone speakers stop functioning properly when the wireconnections to the speaker are broken. This problem often develops when theheadphone cord gets jerked while being worn. The solder connection might alsodetach over time if it was not properly manufactured. The wire can bereconnected to the speaker with a soldering iron to repair the headphone. Beaware, though, that headphones are not designed to be user maintained in thisfashion. In some cases, it is difficult to get to the speaker due to the casingdesign.
Instructions and tools needed
Screwdriver or butter knife (depending on headphone design),Soldering iron, Electrical solder
1 Plug in the solderingiron. It takes a few minutes for it to get warm enough to be used.
2 Unscrew the screws holdingthe headphone casing over the speakers. This step applies only to models thatuse screws in the casing.
3 Insert the end of the butterknife into the seam on the headphone ear pieces. Pry the two halves of thecasing apart. This step is performed only on headphone models that do not usescrews in the casing.
4 Touch the tip of thesoldering iron to the electrical solder. A small drop should melt onto the tipof the iron.
5 Touch the tip of the soldering iron to the end of thedetached speaker wire inside the headphone speaker cavity. Try to get an evencoating of solder around the exposed metal end of the wire. The soldersolidifies on the wire once the soldering iron is removed.
6 Touch the end of the wire tothe solder on the metal tab attached to the speaker.
7 Touch the tip of the solderingiron to where the wire and tab connect. The heat of the soldering iron meltsthe solder on the wire and tab together. This repairs the broken connectionbetween the wire and speaker.
8 Replace the speaker casingonto the headphone. It should snap back into place for models without screws Thanks.

None of the ear pieces work only if I move around the Jack plug thing


sounds like the jack is faulty tghe cable has been pulled and the wire probably stripped off connectors. if you can access a electronics or audio shop purchase a new jack these are cheap and you will need to cut the end off the cable there should be three wires an earth and a left and right cable these will need to be resoldered on the new jack plug.. make sure it is a stereo jack...!!.the best way to solder is to gently heat the cable end and dab a bit of solder on each before trying to attach to the jack. then when you come to connect the jack end lightly touch the connector and cable together with solder iron and solder..good luck A

Instructions how do you repair a loose connection


Hi,

Buy a new jackplug, cut the old one and also 2-3cm of the wire. Then try to resolder those thin wires.
There are two shielded cables, solder the shields together on the ground of the jackplu. Then solder the other two to the ring and tip. Could be very difficult because those wires are very thin, but I'll think you've got no other options.

Regards,
Gerard

Loose connection in Bose headphones


Cut the ******** and replace it with a new one. You will need to solder the wires on to the new one. Keep the old one, cut it open and it will tell you which wires go to which terminal.

Bad connection?


sounds from the description that one connection on the jack is either loose or the connection in ear is faulty if the jack can be taken apart you could try and resolder or the earpieace could be done the same.

My headphone jack is bent and so the headphones barely work.


THE BEST WAY TO DO THIS IS TO GET THE REPLACEMENT JACK FROM AN AUDIO OR MUSICAL SUPPLIES SHOP.. ONCE YOU HAVE THIS CUT BACK THE CABLE OUTER SLEEVE TO SHOW THE CONNECTORS AND CABLES ON THE JACK..GET A SOLDERING IRON READY WITH SOLDER.. STRIP BACK A SMALL AMOUNT OT THE CABLE SLEEVE TO SHOW THE WIRES THEN STRIP BACK EACH OF THE CABLES AND TWIST THE ENDS SLIGHTLY..GET THE SOLDERING IRON HOT AND TOUCH THE WIRE TO THE END WHILST BRINGING TEH SOLDER TO THE WIRE TIP. IF TEH IRON AND WIRE ARE HOT ENOUGH A SMALL AMOUNT OF SOLDER WILL MELT ON TO THE WIRE TIP.. DONT HOLD THE WIRE TO LONG OR THE HEAT WILL MELT THE PLASTIC COATING., DI THE SAME FOR THE OTHER WIRE.THEN UNSREW TH NEW JACK YOU SHOULD SEE EITHER TWO OR THREE CONNECTORS MATCH UP THE NEW WITH THE OLD ON THE CONNECTOR AND SILDER ON ONE BY ONE THE SAME WAY JUST HOLD THE WIRE AND IRON TO THE PLATE AND HEAT WILL CAUSE THE SOLDER TO ATTATCH TO NEW CONNECTIONS..MAKE SURE YOU HAVE PUT THE SLEEVE ON THE WIRE BEFORE YOU SOLDER OR YOU MAY HAVE TO TAKE IT OFF AGAIN TO PUT THE JACK BAK TOGETHER..TAKE YOUR TIME WIT THIS AS IF YOU TRY TO HURRY THE SOLDEDRING PART IT CAN BE MESSY AND NOT TAKE PROPERLY AND CAUSE BREAKAGE AWAY LATER IF THE JACK IS PULLED.. ONCE THE WIRES ARE SOLDERED ON TURN OVER THE GRIPS AND IT SHOULD WORK FINE.. I USUALLY GO FOR THE METAL TYPE JACKS AS THEY ARE STRONGER AND EASIER TO SOLDER.. GOOD LUCK A...

Jack / Cord problem


yes basically if you look at the jack end you should see where the join is it may unsrew then look at the wires in side and the looose one should be seen if not yu can get a new jack from most online electronics Maplin -RS- or any electronics supplier you will need to resolder the wires onto the new connector..make sure you keep the other snipped off connector for reference when resoldering new.. There are a few tips to soldering.. maker sure the wire is twisted before soldering and touch the wire to the solder tip then bring teh solder wire to the wire to tin (melt solder) the end then do the same with other wires. once the wires are tinned bring to plate on teh connector and touch wire to connector and then solder tip to where wire and connector are.. if you keep teh soldering iron on the connection to long you may melt the plastic jack surround so I usually use a metal jack type.. if it has three wires one is for left one for right and one earth..copy the old jack wiring and you should be ok.. Good Luck A

Cannont connect Ear Force X3 with my HDMI set up .


Is the problem that you're using a single HDMI cable to connect your Xbox to your TV? If so, this Turtle Beach article should help... ________________________________________
HDMI and Connecting Ear Force Xbox Headphones
The current Microsoft Xbox 360 series of gaming consoles allow the use of HDMI cables for simpler hookup to home theater systems and Hi-Definition televisions (HDTV).
The Xbox 360 Elite (the black one) comes with two additional cables, an HDMI cable and a separate AUDIO cable that provides a pair of RCA jacks (red and white) and an optical digital audio output (S/PDIF Out). With this cable package, you can easily connect any of our X-series headsets and an HDMI-connected television at the same time.
This Xbox 360 HDMI Cable package is available as an extra-cost option from Microsoft: http://www.xbox.com/en-US/hardware/x/xbox360hdmiavcable/
Here's a more in-depth explanation of the Xbox 360 HDMI Cable and how it works: http://support.microsoft.com/kb/937899?sd=xbox
[NOTE 1:] The standard Xbox models do not come equipped with this cable set. The HD cable they have obscures the HDMI connector, so that the two sockets cannot be used at the same time. If you only have this stock HD connector (component video, composite video, stereo analog audio and optical digital audio connectors), then you will not be able to use the HDMI connector at the same time.
In order to use both sockets at the same time (HDMI and A/V) you'll need to purchase the Xbox 360 HDMI Cable package described above.
[NOTE 2:] The current Xbox 360 Elite Holiday Edition (Fall 2009) does not come with the HDMI Cable set.
___________________________________________________________________
Some companies make aftermarket HDMI cables for use with the Xbox 360, but these may not provide the dual RCA jacks that carry the 2- channel analog audio necessary for hookup of the anlog-only Ear Force X-series headsets. If this is what you have, you may need to find another way to connect your Ear Force X-series headset.
The TOSLINK digitally-connected X-series headsets can be always be connected using optical digital "Toslink" connections (and that's the best way to use them!).
___________________________________________________________________
The oldest white-and-gray Xbox 360 models DO NOT have an HDMI port. With this particular (obsolete) model, you cannot use HDMI connections, but you can use any of our X-series headsets.
Current Xbox 360 models all have separate HDMI and A/V ports ("sockets") on their back panels.
___________________________________________________________________
Here are some suggestions for alternative connection schemes:
XBOX 360 AUDIO PLAYS THROUGH TELEVISION SET:
For X4 and X41: Your best bet would be to connect the Xbox optical digital audio out to the X4 transmitter's optical digital input. Then connect the X4 optical digital output to the optical digital audio input on your HDTV or home theater amplifier.
[NOTE:] Some HDTV systems have an optical digital audio output that will not transmit Dolby Digital/DTS encoded digital audio, only stereo PCM audio will be passed. In this case, you must connect as above.
For X2, X3 and X31: You can use the Headphones jack or the Audio Out jacks on your TV to connect to the Audio In jack on the Transmitter.
For X1 and X11: You can use the Headphones jack or the Audio Out jacks on your TV (if available) to connect to the headset's analog Audio Input.

NOTE: Please make sure your TV has Audio Out jacks. Some TV's only have Audio In jacks.
Audio In jacks only accept incoming audio signal; they do not send audio signal out. If no audio signal is being sent to the headset, no sound will play from the headset.
___________________________________________________________________
You may need to purchase a suitable adapter cable in order to connect the TV audio output(s) to the Ear Force X-series headset's transmitter or Audio Input plug.
- Connect the HDMI cable so that the Xbox 360 plays its audio through the TV.
- For X1, adjust the Dashboard > Settings > System > Voice in the Xbox 360 so that the talkback and game sounds are played together (Play Through Speakers). - For X3, X31, X4 and X41, you should set this to Play Through Headset.
__________________________________________________________________
XBOX 360 AUDIO PLAYS THROUGH HOME THEATER RECEIVER (except X4 and X41): This is exactly the same as the above, except that you will use the receiver's Headphones output jack to connect to the Audio In on the Ear Force Xbox-compatible headset's Transmitter (X2, X3, X31) or the green Audio Input plug (X1).
- You may need to obtain a shielded audio cable with 1/4" stereo phone plug to 1/8" stereo mini-phone plug ends. The 1/4" phone plug goes to the receiver's Headphones jack, while the 1/8" mini-phone plug goes to the Audio In on the Ear Force Transmit- ter (X2, X3, X31) or Audio Input plug (X1).
- Adjust the Dashboard > Personal Settings in the Xbox 360 so that the talkback and game sounds are played together (Play Through Both). For X3 and X31, you may also set this to Play Through Headset.

Replacing headphone connector


My jack plug lead got yanked and broke the wires inside the electronics unit. There are three screws to undo in order to get inside the electronics, one by the cable entry and two very small cross head scvrews in deep holes halfway along the unit. I cut the jack lead on the outside close to the cable entry and drilled out the hole through the cable guide and then poked the jack cable back through the hole into the electronic unit. I was able to solder the three leads to their respective pads. There are five solder pads next to the cable entry. With the cable entry at the top, the middle pad connects to the green cable, the rightmost pad connects to the red cable and the copper connects to a pad about 1 cm down from the rightmost connector. The technique was to tin the ends of the leads with solder before soldering them to the pads. I used a blob of glue from a glue gun to hold the cable in place inside the electronics unit. My plan B if the soldering was not possible was to take a jack plug and lead from an unused set of earpieces and use that lead in place of the original. It would have been much more difficult to replace the lead from the electronics unit to the headset.

Only One Ear Bud Works


It is likely that your right stereo channel has either been severed somehow or there is a severe short in one of the cables. What you can try to do to test this theory is first turn on your music. Then wiggle the cable at the very base of the right earbud. If nothing happens wiggle the cord right where it connects to the stereo jack. If still nothing happens run your fingers along the right earbud audio cable bending and twisting it. If at any point you hear music again then you likely have a short. If it is near the earbud then it is going to be difficult to fix since these earbudfs have a large gauard. If the short is at the stereo jack then the fix is simple. A standard 1/8" stereo jack can be purchased from any electronics or audio store. You can then fairly easily seperate teh old stereo jack and solder this new one in place. Search the internet for tutorials on how to do this if need be. Even if you do not get any kind of sound when wiggling it at the base of the jack this is the most likely culprit since this is where most of the stress on the headphones occur. Be wary though, if you do attempt a stereo jack repair you will void whatever kind of warranty your earbuds may have so check before you try. But, in teh end you may end up saving a 60-100 dollar set of earbuds for 5-8 dollars. Hope this helped.
