low latency, good sound

To get any sound quality boost or lower latency you would need a USB bluetooth adapter. As the system only supports the one SBC audio Codec, which offers mediocre latency and sub-average sound.

Latency and quality will differ only a small amount between different headsets or earbuds if you're directly connecting to the system.

Something like;

or

Its not listed as Switch compatible. I would go with the first one from your original two links or one these;

after a little looking, this skull an co adapter does support LDAC, AAC and APTX LL

Unfortunately the only reputable company making APTX LL earbuds is Sennheiser, so your options are limited;

though these razer and HTC earbuds advertise 45ms and 60ms latencies with AAC. Not sure how much I trust that;
