Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about Cleer Flow II

  • Excellent sound quality with clear mids and detailed highs using 40mm ironless drivers
  • Highly effective active noise cancellation (ANC) that competes with more expensive brands
  • Support for high-resolution audio codecs including LDAC, aptX HD, and AAC
  • Generous accessory package including a high-quality hard-shell travel case and airplane adapter
  • Reliable auto-pause/resume proximity sensor when removing or putting on headphones
  • Fast charging capability providing 2 hours of playback from a 10-minute charge
  • Dedicated physical button for quick access to Google Assistant

What customers don't like about Cleer Flow II

  • Touchpad controls on the earcup are often described as fiddly, unresponsive, or non-intuitive
  • Bulky and somewhat flashy design that may not appeal to all users
  • Clamping force can feel tight or uncomfortable during long listening sessions
  • Lack of a dedicated companion app for adjusting EQ settings or customizing ANC
  • Battery life indicator can be confusing, sometimes requiring users to count LED blinks
  • Ear pads are non-replaceable, which may affect long-term durability
  • Some users report a slight lack of deep sub-bass impact compared to competitors

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.
