What is APTX?

APTX is a Bluetooth audio technology designed to improve wireless music sound quality.

Compared to standard Bluetooth audio, APTX can provide:

• Clearer vocals
• Better bass response
• Cleaner overall sound quality
• Lower audio latency

For APTX to function, both the smartphone and the MR12volt P800 must support APTX codec compatibility. Otherwise, the system will automatically use standard Bluetooth audio transmission.

In simple terms, APTX helps wireless Bluetooth music sound significantly closer to wired audio quality, especially when paired with premium OEM sound systems.
