Pros

Strong Bass: Given the name and driver spec (40 mm), it likely emphasizes bass, which is good for music lovers who like deep, powerful low-end. 

Wireless: Bluetooth connectivity makes it convenient for mobile use. 

Multiple Playback Options: The card insertion / FM version gives flexibility (you can play from TF card without always needing a phone). 

LED Battery Indicator: Good to track battery level. 

Lightweight: 0.3 kg is fairly light for over-ear or on-ear headphones, so they might be comfortable for extended use.

Drawbacks / Things to Watch Out For

Battery Life Unclear: Jumia says “Operating time: 2 hours + more” which suggests relatively short usage per charge. 

Build Quality: As a generic model, long-term durability could be a concern; plastic build (PC+ABS) according to VIP Digital Presence listing. 

Noise Cancellation: Only some models appear to have ANC according to Alibaba; not all variants may support it.
