Sony has launched its latest truly wireless in-ear buds. The new WF-1000XM3 aims to deliver a light-weight alternative to Sony's hugely successful WH-1000XM3 wireless and noise cancelling over-ear headphones.

The only fully wireless earbuds available with emphasis on sound quality seem to be from Hifiman, and it doesn't support any of the better codecs because, according to them, the tradeoff of better codec for better circuits is worth it within the power constraints of an wireless in-ear design. I do believe theirs is going to sound better than this "24bit" Sony though it's non-NC.
