Configuration and appearance.
A set of 3 pairs of silicone attachments of different sizes, one pair is already placed on the headphones themselves.
Wire for charging.
Case of unusual shape with a rubber loop for socks.
The case is worth paying attention to, it is two halves connected by magnets, an interesting solution.
The headphones themselves have beans, by the way they are quite large and made of plastic like the case.
As for the sound, you can feel the emphasis on low frequencies, they do not have speed, and the subbas are quite inflated, so they are not suitable for fast genres of music. Sometimes they creep into the middle range.
High frequencies are set back and somewhat simplified.
In conclusion, I want to say that the headphones are perfect for outdoor and gym activities, having IPX 7 waterproof. Excellent autonomy up to 8 hours from a single charge, Bluetooth 5.0.
I can't call them universal, they are more suitable for non-fast genres of music.
You can buy these headphones in the Hifigo store. Link https://hifigo.com/products/whizzer-b6-ipx7-tws-earphone-true-wireless-earbud-bluetooth-5-0-aptx
