Verdict

The Cleer Flow II is a premium over-ear headphone featuring patented 40mm Ironless Drivers that deliver high-resolution audio with a frequency response of 20Hz–40kHz (wired) and exceptionally low distortion. These headphones provide powerful hybrid active noise cancellation (ANC) capable of suppressing ambient noise by up to 30dB, complemented by an 'Ambient Mode' and a 'Conversation Mode' activated by covering the left earcup. Notable pros include a 20-hour battery life with ANC enabled, 10-minute quick charging for 2 hours of playback, a dedicated Google Assistant button, and support for high-quality codecs including aptX HD and LDAC. However, some users find the touch-sensitive controls to be fiddly or prone to accidental activation, and the 327g build can feel slightly bulky or heavy during extended listening sessions.
