Lotoo PAW S2 - high-end USB dongle
Delivery time approx. 2 weeks
Compact and light but without compromise!
The PAW S2 is the successor to the much acclaimed PAW S1 and has a groundbreaking new circuit design that is impressive despite its small size.
With the addition of the "Remote Control" function, the PAW S2 delivers exceptional audio no matter what you are listening to and wherever you go, and
perhaps most importantly, in the most user-friendly way ever developed.
Powered by the now legendary AKM4377 DAC chip and coupled with Across the entire range of Lotoo's advanced audio technologies, the PAW S2 has once again raised the bar for portable devices for all compact dongle-style USB DACs.
"There is no denial, S2 has Lotoo's DNA, both when it comes to a sound sig and a technical performance, even coming closer to PAW6000 DAP when using IEMs. And while I don't think usb dac / amp dongles going to replace higher end DAPs, they do offer a great opportunity to convert your smartphone into the higher end streaming DAP instead of dragging a DAP in addition to your smartphone. "
"The Lotoo PAW S2 is an absolute recommendation for everyone who is looking for a highly musical and extremely uncomplicated solution to enjoy high-quality music on their smartphone. There is hardly a better way to make a DAC dongle."

High performance and high DAC chip utilization
The engineers at Lotoo have tried to exploit the full potential of the AKM4377 DAC Exploit chips, utilize the chip's capacity and waste nothing to ensure the highest possible performance from the best-in-class hardware.
State-of-the-art DAP architecture
The PAW S2 is a musical powerhouse in your pocket. It comes from the same line as the PAW DAPs (namely PAW Gold Touch and PAW6000) and is incredibly powerful for a device of this size.
The Blackfin® DSP from ADI Blackfin® embodies a new type of 16/32 bit embedded processor with the highest performance and energy efficiency for applications in the industry. It is this powerful combination of software flexibility and scalability that has given the Blackfin wide acceptance in convergent applications such as digital audio systems.
Lotoo has been using DSP technology for over 20 years. Based on the Blackfin® DSP, Lotoo developed and implemented the Lotoo OS, an exclusive operating system that is fully geared towards audio processing.
Advanced 2 × 8 layer HDI PCB design
Analog and digital circuit board sections are completely isolated from each other.
Placing analog and digital conductor tracks on different layers, separated by a ground plane, prevents
digital signal noise from interfering with analog signals. This largely suppresses interference and improves performance.
Low-noise metal film resistors with low temperature drift and millesimal accuracy are installed on the analog circuit board.
Small, robust and yet maximum performance
Panasonic's industry leading polymer and film resistors are designed for a wide range of technologies. Panasonic polymer and film capacitors are designed for the most demanding applications while maximizing performance.
Pure black background
Ultra-low noise floor of up to -121dBu （0.69uV even with highly sensitive headphones. When you listen to your music, every note will shine like a sparkling jewel against the black background. The quiet moments in and between the songs are exactly as they should be thanks to the ultra-low noise floor of the PAW S2.
Independent, high-precision phase locked loop (PLL)
The excellent timing of the PAW S2 takes place via the AK8142, a programmable clock generator IC with an integrated fractional N PLL. It is highly precise and eliminates jitter at the USB and SRC interfaces.
Design & construction par excellence
The G3 curve represents an extreme obsession on the part of designers. By working with reflection lines, the light reflections on the surfaces convey a feeling of luxury and quality. The curved shape lies comfortably in the hand and offers a secure grip.
3D curved glass with cold grinding technology
Die The premium quality of the PAW S2 screen is created by the 3D curved glass, the meticulously CNC-cut glass. The cold grinding process requires the highest precision. The rounded corners of the 3D surface are refined by careful polishing so that the body curvature and the surface of the hardened glass fit perfectly into the slim metal housing.
CNC craftsmanship p>
The aluminum alloy of the "Series 6" is known in manufacturing for its low weight, high strength and excellent workability. Thanks to the 5-axis CNC milling machine, we were able to carefully reduce the thickness of the metal in order to obtain a thin but robust metal jacket and thus eliminate interference and noise.
Lotoo OTG cable and belt clip
This multi-core OTG cable, manufactured exclusively for Lotoo, consists of pure OFC copper with a copper shield mesh and aluminum foil, eliminating potential interference that could affect the purity of the signal. The elegant black jacket made of environmentally friendly TPE material gives the cable both flexibility and strength.
Its high strength, low resistance, high output power and the ability to shield interference signals enable the cable to achieve lower latency and faster dynamic response.
The specially made flexible strain relief is also made of TPE material and protects the cable from breaking or bending. A durable, flexible jacket helps avoid cable stress and broken wires.
Physical buttons on the remote control
The physical buttons on the Remote controls are specially designed for mobile users. The remote control enables easy navigation without taking the phone out of your pocket.
Integrated PMEQ / ATE in studio quality
The critically acclaimed PMEQ / ATE, which is only featured in the top DAPs from Lotoo can be found, is contained in PAW S2 with new additions. Try this function with your favorite music, a game or even a movie, and let yourself be enchanted by the impressive soundstage, the precise reproduction and breathtaking details!
