XZ-U606P Pro HIFI Fone de Ouvido Portátil de Alta Corrente com Bateria - Mini Amplificador de Fone de Ouvido

Introduction: This headphone amplifier has a very sweet sound effect, and you can feel a significant increase in the sound field, resulting in better resolution. Highlight better vocals and a sense of hierarchy. Voice is sweet and beautiful!!! Low frequency has a texture. This needs to be specifically explained. Low frequency has quality and quantity. Very good control. The elasticity is very good. The overall spatial positioning has been significantly improved, with more details. The XZ-U606P Pro has the following practical enhancements: Low battery indicator function - When the battery is low, the power indicator light flashes for 0.5 seconds, providing personalized reminders ◆ Turn on the earphone output protection after a 2-second delay in power on (to ensure stable circuit power supply before turning on the earphone output, to avoid damaging the earphone instantly when powered on). Equipped with earphone protection, when there is a circuit fault, the earphone protection will work. The earphone output will be cut off and the power indicator light will flash for 0.2 seconds, indicating a fault . ◆ Fully symmetrical amplifier power supply circuit - capable of providing high current positive and negative power supply, improving signal amplification bandwidth and dynamic response, supporting simultaneous input of audio and USB charging for computers and other devices (no longer a virtual ground power supply circuit) . ◆ The new solution further enhances power efficiency (with a battery life of>9 hours (usually 9-12 hours), which varies depending on different usage conditions) . ◆ Adopting an IC socket and replaceable operational amplifier design (standard encapsulated DIP-8 operational amplifier), it has high playability. XZ-U606P Pro matched with MC33078P operational amplifier (Beyerdynfeelic) The original operational amplifier model of A1 earbuds). You can also replace the following operational amplifier models; For example, OPA2134PA/OPA2604/OPA2107/AD712/AD827/LME49720NA/MUSES8820/MUSES8920/MUSES01/MUSES02 can be replaced and used directly. Standard MICRO USB 5V charging interface, connected to the charger, the machine's red light comes on. After approximately 3.5 hours of full charge, the red light goes out. The machine can play while charging. The machine is equipped with an overcharging and discharging function, and will automatically stop charging when fully charged.
