In order to enjoy high-quality audio with this particular set, it is best that your sound source does support LDAC codecs, with a bandwidth of up to 990 Kbps; our trusty Huawei P30 enabled LDAC as soon as the headphones got connected, so no issues here. After listening to many audio clips on YouTube, FLAC albums and different podcasts on SoundCloud, we can say that it covers the whole spectrum optimally, with a decent amount of bass (if mounted with the correct tips in order to provide a good seal). The voices are clearly rendered, so we haven’t had issues while watching some TV shows on the smartphone as well. Versus the Stylish True Wireless In-Ear, this particular model does have the microphone mounted in a closer area to the mouth, so expect no issues taking phone calls or chatting for longer in conferences via Skype.
