Question about Sennheiser MM 550 Wireless Headphones
I am using this headphone since a while. But I have a problem. Around the center button, a blue light always keeps flashing.. Once I switch on the headphones, it keeps flashing forever, does not matter if I am on a call or listening to music or not doing anything. Initially it was not like that, one day I pressed some buttons on it, I dont remember in which order I pressed, but since then this blue flashing light has started, never ends unless I switch off the headphone. I am not able to switch it off. 2 of my friends have the same headphones, but they do not have this issue. The headphone is working fine otherwise, but after paying that money, I am sad that it has this problem. It id disturbing for the co passenger when I am traveling in the night in flight or train
1. turn it off2. hold centre button until blinking blue and red3. briefly press volume down4. turn it off= fixed :)

I have been having the same problem and was completely unable to stop it. While searching for a solution today I tried everything but eventually connected to my iPhone via Bluetooth, which stopped the flashing, and then clicked <Forget this device> on the iPhone and the flashing did not return. In the past 20 minutes I have connected to my Mac, my iPhone, wired and via Bluetooth and the problem seems to have disappeared (I hope).

Most faults in headphones are caused by either a broken cable or a faulty plug. Try moving the cable or plug around in various places to see if it come back on, look for wear or a break too! If you find it you will have to replace the plug or cable. The only other cause is a faulty speaker, but they are not common.

They need a minimum level of signal to switch on the transmitter.
Verify if it works on yet another system.
Make sure you have the right output on your Samsung.
Try to increase the output level of your Samsung...(up the volume, but it may be a fixed output..)

You have a break in the cable. You don't say in what area it's in, so I will have to give you 3 ways of clearing the fault.
1: Break in, near or around the plug. The best solution is to cut off the plug making certain the break area goes with it. You can then fit a new 3.5mm plug. If you need advice on how to do this let me know.
2. Break halfway to 2-thirds along the cable. Again cut the cable to a point clear of the break, again fit a new plug. To extend it you can purchase an extension headphone cable from any hi-fi shop.
3. Break to close to headset. In which case you will need to replace the entire lead. To do this you need to open up the headphones. Access is obtained by removing the pad(s) and any foam. You might need to force the foam off. You can glue it back on afterwards. You should then see screws to open it.
Fitting new plugs or attaching the wire inside will require the use of a small soldering iron.

I have got exactly the same problem with mine. Mine are RS140.
So if there is anybody that can help with this I would be very happy to find out what the problem is (as only used them twice)
