Description

【1】Intelligent noise reduction, clearer and more detailed human voice, built-in noise reduction chip, using Ai noise reduction algorithm, strong anti-interference ability, can effectively identify the original sound in noisy environments, and still be able to clearly record.

【2】3.5mm plug is suitable for various devices and scenes, such as SLR cameras, digital cameras, car audio, subwoofers, power amplifiers, speakers, sound cards, and other devices. Suitable for lectures, teaching, training, small conferences.

【3】Adapter combinations (F, G, H) have been added. It can charge the receiver during use. It can support Type-C Android phones or sound cards, iOS phones, and computer USB ports. Some Android phones need to manually turn on OTG mode. Settings - Search for "OTG" - Open it. (About purchasing an iOS adapter combination and using it on iOS phones. Please note that within 10 seconds after insertion, there will be two disconnects and reconnections. This is a normal phenomenon caused by two matching during system adaptation and charging. Please do not worry. After 10s, it can be used continuously and normally. If the prompt "This accessory is not supported" is displayed, replacing a high-quality charging cable can solve the problem.The adapter passed a test before being shipped.)

【4】There are two adapter options on the market:

One is to use a 3.5mm plug to convert to a TypeC or iOS interface for Android and iOS phones. This scheme is to convert the analog audio signal of the 3.5mm interface into a digital audio signal. Due to the limitation of the adapter chip's resolution ability, it will be distorted and even generate electroacoustic signals. And this solution will occupy the phone speaker and Bluetooth headset or Bluetooth speaker, requiring the device to be unplugged to hear sound. Very inconvenient. So we have eliminated this scheme.

The second scheme is the upgraded OTG transfer scheme: This scheme directly outputs digital audio through the TYPEC interface at the bottom of the receiver, and transmits it to TypeC Android phones or iOS phones, as well as computer sound cards, through an OTG adapter. It is directly parsed by the terminal device, and the sound quality is perfect without loss. The biggest advantage of this scheme is its flexible configuration, which does not occupy the external playback of devices such as headphones or speakers. Without unplugging the device, you can still directly play the sound or even connect to Bluetooth headphones or audio to play the sound. Very convenient. Our 2023 K35 supports this feature.

If the microphone is used by the 3.5mm AUX of mobile phone, please note that the microphone should be turned off power, and then plugged into the mobile phone before turning it on power. And the status bar of the phone displays the microphone headset icon instead of just the headset icon. You may need to try several times until the correct icon appears, as shown in the following figure:
