LTTP Hi-Res Lossless Transmission True Hi-Fi, now wireless

The PAW S3 brings Lotoo's proprietary LTTP Hi-Res Lossless transmission technology to a portable DAC/amplifier format. With transmission rates of up to 1.5 Mbps, LTTP overcomes the bandwidth limitations of conventional Bluetooth audio transmission and supports:

• 192 kHz / 32-bit Hi-Res Audio

• 48 kHz / 24-bit Lossless Audio

Paired with a Lotoo WT1 or WT2 LTTP transmitter, the PAW S3 forms a complete wireless Hi-Res Lossless audio system, giving wireless listening greater detail, dynamics, and depth.

LTTP Wireless + USB DAC

The PAW S3 is not limited to wireless playback. It also functions as a powerful USB DAC. Its USB Type-C port lets you connect it to a smartphone, computer, or portable player to switch to USB DAC mode, with support for PCM up to 768 kHz and Native DSD512. Whether wirelessly via LTTP or through a USB cable, the PAW S3 is designed to deliver consistently high sound quality.

Professional Audio Architecture Designed for the highest sound quality

At the heart of the PAW S3 is the AKM AK4493SEQ, combined with Lotoo's many years of professional audio design experience.

The PAW S3 supports:

• PCM up to 768 kHz

• Native DSD512

Key audio specifications include:

• THD+N: 0.0004% (1 kHz, A-weighted)

• Noise floor: extremely low, down to 0.7 µV

The low noise floor helps preserve fine details and ensures a clean, quiet background during playback.

Powerful output Ready for a wide range of headphones

The PAW S3 delivers:

• 550 mW @ 32 Ω via the balanced 4.4 mm output

• 250 mW @ 32 Ω via the unbalanced 3.5 mm output

It also offers adjustable line-out levels, providing users with greater flexibility for different device configurations. 

LTOS Professional Audio Operating System

The PAW S3 runs on LTOS, Lotoo's proprietary professional audio operating system, and offers the PMEQ parametric equalizer and ATE sound tuning. A 2.0-inch IPS color display ensures that the most important playback information is clearly visible at a glance.

Long battery life and compact design

The PAW S3 features an integrated 3300 mAh battery for up to 10 hours of extended listening. Its stainless steel housing features a titanium PVD coating. Measuring just 87x55x21 mm and weighing approximately 180 g, it combines a premium feel with excellent everyday usability.
