Bluetooth limitations: According to some sources, Bluetooth mic doesn’t work in certain devices (or is disabled on some consoles) — e.g., “mic disabled in Nintendo Switch Bluetooth mode.” testmarket.io
Not Xbox-compatible: Some listings mention 2.4G / Bluetooth modes are not compatible with Xbox Series. wootplus.com
Build quality: Being a budget / mid-tier headset, it may not feel as premium as more expensive brands.
RGB drains battery: As with many RGB headsets, using lights reduces playtime a lot.
Mic quality: While OK, it's not “studio” grade; some users say it’s decent but not amazing. Fakespot
Brand support: Fachixy is a lesser-known brand, so after-sales support / warranty might be less accessible than big brands.
