Micro-USB Charging Port Replacement

Passo 1

Remove the foam pad by pulling up on the foam until it clears the groove.
Working around the foam, carefully slip it off to reveal the screws.

Passo 2

Remove the 4 screws holding the speaker enclosure to the main body.
Do not fully lift off as the speaker is still connected to the board.

Passo 3

Desolder the speaker to fully remove it.
Desolder the mic and speaker conncetions
Desolder the battery connector.

Passo 4

Remove one Phillips screw, holding down the board
The board is also held in by clips, so use a prying tool or just fingers to pull upp on the board to release it.

Passo 5

You successfully removed the main board.
You can see the damaged USB connector

Passo 6

Apply Kapton tape to ensure protect the plastic components like, switches and the jack conncetor.

Passo 7

Apply flux to the top pins and the mounting pins (underside) to help solder flow.

Passo 8

Grab the connector with tweezers and apply heat from the mounting pins' side (bottom).
Be careful with the hot air station and position the board in a way that you do not burn the jack connector while heating up the port.
320 degrees (Celsius) with 20-30% airflow is more than enough to get the connector off.
Clean the pads with a solder wick.

Conclusão

To reassemble your device, follow these instructions in reverse order.

Very good tutorial, I'm looking for the WH-CH700N board, but cannot find any retailer for buying it. Do anyone knows any online shop or service that is selling it? Thanks

Hi @rogerhutton

I found these to be a suitable replacement and fairly inexpensive:

Hi there!

Thanks fot a great guide!

When it is opened, is it possible to change Micro USB to USB-C? Would it work?

Have a nice day,

у меня вопрос если при заряжании наушников нужно было пошевелить и завиксировать кабель чтоб оно заряджало (танцы с бубном )а потом мне в сервисе говорят что это контролёр умер но явно ж проблема в микро юсб?верно?

I have a question if, when charging the headphones, it was necessary to move and wiggle the cable so that it charged (dancing with a tambourine) and then they tell me in the service that it was the controller who died, but clearly the problem is in the microusb?

Hi @honakrisi

I found this pair of headphones at a flea market. I opened them and found this improvisation on the power jack. Can you tell me if it was done correctly? I also replaced the battery because it was no longer good and the headphones work but when I try to connect them to charge nothing happens.
