Review on Sony WF-1000XM3 Black Truly Wireless Earbuds with Mic, up to 32 Hours Battery Life, Stable Bluetooth Connection, Wearing Detection and Alexa Built-in for Noise Cancelling by Agata Buczkowska  (B ᠌

When I initially put on my clothes in the morning, the sound has a "wow" impact, but after about five minutes, my brain adjusts and the bass begins to beat on my skull. The equalizer has no positive effect. Another option is the Bose qc30, whose "engaged" sound and spacious design give the impression of much higher quality. In this respect, Sony is lacking. Sony paid for everyone's opinions on their headphones, including the most prominent ones, thus the sound is basic and the noise cancellation isn't as good as they advertise. It's inevitable that your headphones will escape your ears. Sitting still and not breathing causes them to stay put even if you insert them into your ears and turn them 90 degrees. If anything, the sound quality suffered once I replaced the ear pads with a spinfit 360. The headphones have never provided me even a moment of happiness.
