Yes Bluetooth adapters will have compression/etc. but it doesn't really ruin the audio quality since it's the best that we have right now with the technology for us general consumers.

For sound degradation, it depends on your environment and how loud your listening levels are. Some people will hear the inherent Bluetooth compression more, others will be able to ignore it after a while or so.

At safe hearing levels and also when outside, people probably won't be able to easily tell the difference due to the external noises competing with the sound/music. Like even when at home at louder volumes some people also can't tell between wired and wireless, when using LDAC, AptX, etc.

Like they just released the Qualcomm QCC 5171 chipsets and so for 2023, there should be some more Bluetooth stuff with Bluetooth 5.3, LC3 tech, AptX Lossless, et cetera.

Try to get the KB9P AptX Adaptive USB transmitter dongle, there's some software for it called Dongle Assistant, see here for more info on those AptX Adaptive and AptX Lossless dongles and Bluetooth stuff: https://www.head-fi.org/threads/aptx-adaptive-aptx-lossless-usb-transmitters.961856/page-55

Here's more (direct) updated info about the AptX Adaptive USB transmitter dongles (KB8P, KB9P, YET-T10P): https://www.reddit.com/r/headphones/comments/zr41fe/which_lossy_codec_to_use_compress_with_before/j12cdwt/

Here's more info on TWS adapters like the FiiO UTWS3/5, KZ AZ09 Pro, etc. alongside adapters/converters, AptX Adaptive dongles (KB9P, YET-T10P, etc.), and so on needed for them: https://www.reddit.com/r/HeadphoneAdvice/comments/zvmt4a/wireless_zero_other_wireless_earphones/j1q2s6f/

The KB9P is usually from AliExpress (often takes 1-3 weeks for delivery if you live near an international airport), but you can sometimes find the KB8P/KB9P/etc. on Amazon under different names, just look at the pictures on the product images if it seems like it'll be the KB9P and so on.

As for the PC motherboard, there's Intel AX210/etc. Bluetooth/WiFI (PCIe) cards available for like say $40 or so. Those only have regular AptX available but it lets you see the devices names, initial battery level, et cetera.

But ya better to get the KB9P AptX Adaptive USB transmitter dongle as it's like half the price at $20 and then you also get way more features for Bluetooth. As part of the cost for the Intel AX210 is the WiFi portion that isn't really relevant to Bluetooth audio.

Btw disable WiFi when not using it or make sure your routers/etc. are a bit further away as sometimes those can interfere with the Bluetooth TWS earbuds range and connection and so on. Like you'll maybe hear static/interference or having cutting out issues if you have like a congested area and such.
