For most people, a decent pair of wireless earphones/headphones from companies like Sony, bose, sennheiser, etc. in the $200-$500 price range will be the perfect mix of quality, convenience, and price. Obviously, if quality is of the utmost importance, more pricy options from even better brands, that have much better DACs and sound systems exist, so if you're really wanting quality you can explore that route. That said, those options are for the much more extreme audiophiles. For every day use, I personally think those options are overkill. That said, I would never buy anything in the $30ish price range, you are almost guaranteed to get something that sounds and operates like trash.
