Sony WH-CH720N: Why are my Sony making weird popping sounds when I plug it in/power on

Mon, 16 Feb 2026 22:57:37 -0700

So I was wearing my headphones at school today and they were perfect. I go home and use them for a little bit and leave them on just in case I want to listen to music. I look at my phone and suddenly they are no longer connected to Bluetooth. Could this be a battery issue?

Sony WH-CH720N: The power button isn’t working anymore

Fri, 19 Dec 2025 21:45:45 -0700

i’ve had this problem for a couple days. I clicked the power button and hold it, but it doesn’t do anything. The headphones don’t turn on nothing. I know it’s still functional cause if I push it sometimes it turns on for some reason extremely inconsistent. Could someone please help with this? I’m thinking of getting a replacement. What type is the button?

Sony WH-CH720N: One of the Headphones is only on by a wire, how do I fix

Wed, 23 Apr 2025 19:20:21 -0700

I pulled on my headphones a little hard and this lead to the right headphone popping off the hinge, and is now only dangling on by the wire, surprisingly still fully working (seems like that wire is pretty sturdy), some other bits of plastic that usually would be around the hinge also snapped off. I don't really have the ability to buy tools for this and I did try blue tac and tape but to no avail the break is just too far in the mechanism to fix it like this. If it is something that I need to get a repair for how much would it be I have a max budget of maybe £30, Could I superglue it? Im not really bothered if it removes the hinge functionality all I care is that it will hold for lets say maybe 2 years or so. Thanks a lot.

Sony WH-CH720N: Sony WH-CH720N won't charge after water incident.

Sun, 23 Feb 2025 13:24:46 -0700

My Sony headphones got dunked in water accidentally. I quickly pulled them out and towel dried them off. An hour later I put them in rice and let them sit for 24 hours. I didn't make sure they were powered off during this time so I might have ruined them. When I pulled them out of the rice, they did not turn on. When I tried to charge them, the light next to the usb-c charging port does not turn on. I opened the earphones up (see pictures) and noticed the battery and USB port are on different sides of the headphones. If the charging light doesn't show when plugged in , I'm guessing its an issue with the charging circuitry and not just a battery issue? Id love to fix these if possible since I've had them for less than 3 months. Not sure I'm up for resoldering a USBC port into the headphones but it would be nice to know what the best way to fix these would be, if there is a solution?

Sony WH-CH720N: Slide Headband Not Working

Thu, 09 Jan 2025 17:58:14 -0700

I recently got my WH-CH720N headphones for Christmas, when a few days ago the extendable part for the headphones broke. The left slide will now slide freely instead of it having the 'sections' the right side has. Is it possible to to fix this myself, or do I need to return it, and get it fixed? I've already tried to see if I can get the plastic off, but can't. I also hear a rattling noise in it, presumably from the piece that broke.
