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.
