After all those positive reviews and recommendations, Maxwells turned out to be a huge disappointment for me.
The sound quality is good, tho for me it wasn't anything spectacular when compared to currently owned headphones.
Overall build quality is good, however "power" button has tactile "plastic click" that makes it feel like it's very cheap.
The app for iOS is terrible, with constant connectivity issues, massive lag after applying the EQ settings (c.a 5 seconds), and at some moments keet randomly changing the settings (turning on/off side tone for example).
USB Dongle for PS had constant pops/clicks in audio transmission, dual connection did not work as expected - app prompted to unplug USB in order to be able to change settings...
Comfort-wise, I was not able to adjust the head strap - there were either too low or too high. They grip the head not too tight, so paired with soft pads you have a feeling that they might fall off one a moment (compared to Beyerdynamics that cuts off blood flow around your ear).
For me, they were intended for primary use as a gaming headset, but the overall issues with the comfort and usability were not justifying the purchase, since audio quality was similar to currently owned ones.
