I bought wireless headphones a month ago, and they work fine with my phone, but when I connect them to my laptop via Bluetooth, there's a constant high-pitched noise. I've already reconnected them several times and restarted the laptop - nothing helps. Is this some kind of compatibility issue, or do I need to change something in the settings?
I had a similar issue with my headphones - the whistling turned out to be interference from my laptop's Wi-Fi module, especially when it was actively transmitting data. Try turning off Wi-Fi for a bit and check if the whistling goes away to see if that's the problem. If it helps, then it's definitely frequency interference, and you can fix it either by moving your laptop farther from the router or updating your Bluetooth drivers - sometimes newer versions work more stably and conflict less with the network module. I'd also suggest checking the volume in your laptop's sound settings - sometimes at maximum volume headphones start crackling or making weird noises even if everything's fine with your phone.
