The quick answer is NO
For live music monitoring, this kind delay might not be enough. So if you are working in a studio, or playing instruments at home, we do not guarantee this Bluetooth aptX LL adapter can meet your requirements.
Typical scenario not recommending Bluetooth adapter could be:
1. scratching on turntables / DJ Live Music Streaming
2. Professional studio or live video for audio monitoring
3. Use combined with wired systems (Speakers + Wireless Speakers)
4. Professional use and real-time SAFETY-CRITICAL applications
If you practice keyboard at home and use a pair of aptX low latency set at home, or blogging with microphone, it is OK. but not in real time critical missions.
