This is my pair of AKG k240 MkII. I posted about it 9 months ago here: https://lemmy.blahaj.zone/post/7345872 Since then I grew tired of the original braid and made a new one.
I also wanted to go wireless so I bought the FiiO BTR5 dac/amp which has bluetooth. There’s lot’s of cheaper BT receivers online but since they are typically advertised for usage in cars I worry about their latency; I do video work so I need low latency to synchronize sound effects, lip sync etc.
I’ve only ever had bad experiences with BT audio on Linux so I’m pleased to say the BTR5 works almost flawlessly. No issues with pairing or automatically choosing low quality HFP audio (I’m using LDAC; supposedly the BTR5 supports AptX-LL but I’m not seeing the option to enable it, maybe my BT adapter, TP-Link UB500, does not support it, I don’t know)
Range is not as good as some other BT headphones I’ve tried, after a few meters it starts to occasionally cut out. Still far more convenient than cable.
The cable is a bit too long (30cm) but it was the shortest one I could find. I don’t know how to make custom cables.
For the price of all of this I probably could’ve bought better headphones but these purchases were made a few years apart. Plus I kind of like how janky it is, makes it feel homemade even though its all mass produced :)
I don’t think so? But I’ve never had the problem you describe. Yes they do make a little bit of noise when putting them on, mostly from the headband being adjusted, but after that they’re quiet.
That’s the noise for sure, I seem to notice it every time I move my head. I’ve had the K271 mk II for like 15 years and they’ve lived in a pelican hard case any time they weren’t on my head for the first 13 of those years and a cheaper hardshell case from amazon for the last 2 years or so. Its not like they’ve been abused at all.
