2.4G digitale Funkkopfhörer-SOYO WH2009A

2.4G Hi-Fi Digital Wireless Headphone SOYO-WH24G01A Features 1. Long distance transmission. The stereo audio can be transmitted in over 100 meters open area (no obstacle, the test is under static status) 2. Supporting point to point and point to mass transmission modes and unlimited receivers. 3. Up to 20 selectable channels, simply to avoid interference. the item works in 2.4GHz ISM (namely Industry, Science, Medicine) band, with 20 channels for selection, meeting the needs of Multi-frequency and frequency hopping. If there is strong noise and interfere in the current channel, users just change a new channel to get a good effect. 4. The shortest latency. The latency of audio wireless transmission <0.5ms, which is the top standard in the industry. 5. The highest audio sampling ratio 64K, Hi-Fi HDCD sound quality 6. 20Hz 20 KHz frequency response.Please note that it’s an actual test data, quite different from some products in the markets which don’t meet this standard but be marked with exaggerated advertisement. 7. Ultra-low power consumption design. The lowest power consumption provided in the industry, the transmitter current can be adjusted from 40mA -110mA directly according to users’ request, the receiver current is lower than 35mA and the current is less than 5mA in standby. 8. Be equipped with high capability Lithium-ion rechargeable battery, charger offered, it can work for more than 30hours after each full charge. 9.
