SNACK: 3-line summary
SNACK in 3 lines
- A September 26 report describes the LEWITT LW6 closed-back studio headphones and their dedicated RealSound link.
- Bluetooth 5.3 uses SBC/AAC; USB-C and 3.5mm offer wired alternatives.
- RealSound needs the bundled LW TX transmitter and a compatible source; South Korean and Japanese retail launches remain unconfirmed.
LEWITT’s LW6 gives studio users a choice of wireless and wired connections, but its low-latency claim applies to one specific setup. As described in a September 26 Best of High End report, RealSound uses the bundled LW TX transmitter rather than the headphones’ ordinary Bluetooth connection.

Red Could a wireless recording setup let me move around without keeping track of a cable? That’s what I’d want to try.
AIKO I’m interested in the separate LW TX link. Bluetooth isn’t a shortcut into that uncompressed RealSound mode.
RealSound and Bluetooth take different paths
RealSound is a proprietary uncompressed PCM link. LEWITT claims latency below 6 ms within five metres and rates battery life at 21 hours in this mode. Bluetooth 5.3 supports SBC and AAC instead; neither the latency nor battery figure should be assumed to apply to Bluetooth listening.
Wired connections when the transmitter isn’t an option
The LW6 also accepts USB-C audio at up to 24-bit/96kHz PCM or a 3.5mm analogue input. Those alternatives matter if a source cannot use the LW TX. Retail launches in South Korea and Japan remain unconfirmed.
