Third-party reviews

What customers like about Coumi ANC 551L

  • Modern, sharp design featuring metal grilles that resemble open-back headphones
  • Comfortable ear cups suitable for long listening sessions
  • Zero latency issues reported, making them reliable for general media
  • Included travel bag/pouch for safer transportation
  • Impressive battery life for the price point, offering up to 18 hours
  • Convenient on-device control panel for volume and playback
  • Foldable design enhances portability

What customers don't like about Coumi ANC 551L

  • Lacks actual Active Noise Cancellation (ANC) despite the model name, providing only passive noise reduction
  • Headband curve can feel too wide or far from the head for some users
  • Ear cups may be slightly narrow, leading to ears touching the interior
  • Microphone does not feature dedicated background noise cancellation
  • Voice prompts during mode switching can sound 'crackly' or low-quality

Verdict

The Coumi ANC-551L is a pair of over-ear wireless headphones featuring 40mm dynamic drivers with a frequency response range of 20Hz to 20,000Hz and an impedance of 32 Ohms. Key characteristics include Bluetooth 5.0 connectivity, a 520mAh rechargeable battery providing up to 18 hours of playtime, and a foldable design for portability. Main pros include a lightweight build of 226.8g, a 3.5mm jack for wired use, and a built-in control panel with four microphones for headset functionality. However, despite the 'ANC' branding, some technical listings indicate it may lack true active noise cancellation, and it features a relatively long 2.5-hour charge time compared to newer models.
