The Lekato WS-100 is a compact, rechargeable wireless guitar system designed to free musicians from cables during practice or performance. The system, which operates in the 2.4GHz range, includes a transmitter, a receiver, and a portable charging case that provides extra battery life. 
Key features
Wireless operation: Uses the 2.4GHz ISM frequency band for a strong, stable signal with low latency (less than 6.7ms), providing a wireless range of over 100 feet in an open outdoor area.
Charging case: Comes with a portable charging case that can recharge the transmitter and receiver twice over, extending the total playtime to approximately 18 hours. A single one-hour charge provides about 6 hours of use for the individual units.
Dual-plug design: The 190° rotatable plugs have both 6.35mm (1/4") and 3.5mm (1/8") jacks for universal compatibility with a wide range of musical instruments.
Multi-channel support: Supports up to four sets of devices running simultaneously without interference, making it suitable for a band setting. One transmitter can also broadcast to multiple receivers.
High-fidelity audio: Offers a high-resolution 24-bit/48KHz sampling rate and a dynamic range of 105dB for clear, lossless digital transmission.
Simple setup: Features a user-friendly, plug-and-play design with automatic pairing, so you can start playing in seconds.
