The Audio Technica ATH-M30x headphones are lacking something, the oomph that makes music sound great. Perhaps my phone just can’t drive them properly, but I do notice the same issue running through my computer and my tablet. Some listeners will praise the treble clarity but most will be bass-hungry on their default settings. I would highly recommend stepping up to the M50X or looking at another brand.
While taking into consideration that the Takstar is by no means a professional mic, the audio from it is alright, with a good amount of warmth and punch. However, don’t expect miracles from it- because it is quiet, the mic works best in close range. I would suggest using it for vlogging, close-up interviews or voice recording on a computer. And keep in mind you’ll likely have to spend time editing out background hiss.
These headphones have been my daily driver for over a year now and are constantly proving themselves to be a decent set of Bluetooth headphones in their price range. For under $60 US, you absolutely can’t go wrong, especially if you love heavy bass. However, if you do purchase these headphones, treat them gently as the build quality seems a little questionable.
