Re: how to replace blown driver.

By the time you buy a driver from Sony for $78 you may as well just buy a whole new set for $94.

Bass (low frequency) completely missing?

Why is the impedence of the phone.
32 ohms impedence will work well.
16 ohms suit only particular sets.

Distorted sound

Never used them, but distorted outputs indicates you are over-driving them, connected them to 'speaker out' rather than 'headphone out', Or you have already blown the drivers. Connect to a different sound source and see how they work then. You likely will not get a loud boom from any headset.

Hey there. I own a pair of Philips SHL8800s (great bass btw), and after 2 months of use, the left side stopped working. The right works great, as usual. I read Grubhead's post and tried to determine...

it's prob a loose wire inside. however i dont recommend you repair it at home. it's tedious work and it won't look good after. suggest you get it repaired.

I have the RS120. It worked ok for about 2 years and then the right side stopped working. The left side works just fine. I opened up the sides and it seems that there is no broken solders or anything...

well it seems your right earpiece is started to get broken...clearly saying that the coil has static and would result to an open coil.....try to replace with a new one...good day...

How can i open my AKG k141 studio headphone to repair it ?

I had a problem with my AKG K141 Studio headset. The right side stopped working. Hard to believe but one of the leads to the ear speaker was disconneted from the solder lug. To disassemble, pry the gold AKG emblem using a jeweler's screw driver. You can pry it without damage by locating a small notch on the black plastic rim at the 6 o'clock position. Then unscrew ththe tiny phillips screw and remove black disc. You will see two leads (red and white) feeding through a hole. Disassemble removing a larger screw. This will give you accesss to the solder lugs.

The Right side does not work.

i just bought the turtle beach x1's and had the same problem only it was the left side not the right and i was pushing the green audio connector cable to close together with the av componet connector and just slightly removed the audio cable from the av connector cable basically just slightly remove the headphones from the connection port on whatever you are connecting it to if that dosent work then most likely you have a lose connetion port on your device and will need to replace it or replace the device alltogether if the port can not be replaced.

MDR-7506 - No sound on right side

It sounds like the pin cracked. If this is the case, you'll need to soldier a new jack on it. Here's how, assuming you already know how to soldier a new 1/8" TRS phono plug.

Cut and strip the cord. There should be two copper wires and (on Sony headphones, at least) a red and a green strand. On a new 1/8" jack, there should be three connections. The middle one is left, and is where the green one goes. The short one on the side is right, and is where the red one goes. The long bit is the common, and is where the copper one goes. Before you solder, however, remember which strand is which, because you have to sand or burn off the colored enamel. (Use a fine grain paper, or use a standard lighter or stick match- anything else might damage or melt the wire)

Right side gone dead.

It's difficult to say exactly what the problem is without being able to actually test them with a meter.

Unlike speakers (where you have a separate woofer & tweeter) the headphones only have a single driver per ear, so the loss of high frequency is unlikely to be a driver problem.

The place I would start looking at is the lead. Damage to the lead (or rather the internal conductor) or the plug can often result in a drop out of high frequncies.

The K240's are not discontinued, but you might be able to still pick up a replacement lead.

Hope this helps,

Less sound on one ear than the other

Yeah, based on all of your problems, i would safely say that you have a blown speaker. Call up Bose at 1-800-999-2673. If the headphones are under warranty (1 year) they will replace them for free. If now, they will charge you $100 for a replacement pair, which is quite a deal considering that the headphones cost $300.

On my MDR-7506, there are 4 screws, not one. Slip the ear pads off (they should pull off intact; don't worry) and the screws should be visible on the face of the driver housing. Remove the screws and you'll gain access to the wiring behind the drivers. You'll see the right side driver's 2 wires attached to the back of the left driver. I believe the ground wire is gold and the signal wire is red. In my case, my right driver is the one that's gone silent on me, and the culprit appears to be a frayed ground wire over on the left side. It's frayed right where the 'bare' (micro-insulated) wire leading from the left driver enters the protective black tubing that leads to the right. There might be just enough slack to cut and resolder it, but there's no margin for error. Does anybody have tips for working with these very fine wires?

A service "manual" (really more of a parts list / exploded view) is here (for now).
