It’s been 4 years since I bought the JBL E45BT wireless headphones. Now it has poor sound quality, doesn’t connect to any device easily & also the cable which connects the headphone-laptop doesn’t work either. Is it not usebale anymore? Please help. Thank you!
Hi @a51 Poor sound quality may be due to a failing battery. Even rechargeable batteries have a lifespan. Try changing the battery and check if the sound is better. Here’s a video that may help. I realize that it is not about changing the battery but it shows how to open the headphones and then the battery can be accessed (see battery at 1:19 minutes into the video) and disconnected from the circuit board and replaced. Search online for CS-JBE300SL battery to find suppliers that suit you best. As to why the 3.5mm stereo audio cable connection to the laptop doesn’t work it may be a faulty jack in the headphones or the jack may have come loose from the board. Have you tried using a different compatible cable just in case it is the cable that’s faulty?
