What is a Telephone Headset?

Phone headsets are designed for voice transmission, and are mainly connected to a phone box or computer for use in offices and call centers.

1.

Telephone headset related accessories: headset quick connect cable (also called QD line), headset dialer, headset caller ID dialer, headset amplifier, headset accessories, etc.

* (United States) Underwriters Laboratories, UL (Underwriter's Laboratories), has determined the safety limit of 118 dB after studying the sudden noise.

* The U.S. Occupational Safety and Health Administration, The Occupational Safety & Health Association (OSHA), limits noise intensity to 90dBA when exposed to a noisy environment for extended periods.

1. The sound quality of a good call headset is clear and soft without noise interference.

2. A good anti-noise microphone can shield more than 75% of background noise.

3. Try to choose the position of the head card using stainless steel design, which is durable and saves a lot of costs.

4. Some earphones are equipped with quick plug and unplug cables (QD link cables), and have a sound blocking function.

5. Head clip: The head clip and connecting parts are reliable and durable, and can withstand more than 30,000 normal wearing bends

6. Interface: The standard 3.5mm interface of PC sound card is used to connect the agent. The cable has a QD fast interface and can withstand more than 20,000 mating cycles.

If there is noise in the phone headset during a call, you must first distinguish where the noise comes from. If there is noise on the other party's phone while there is no noise on the other phone call, it means that the other party's phone The noise has affected the conversation between the two parties. If there is noise coming from every phone in and out, it means that there is noise in your phone. This noise includes both line noise and telephone noise. Line noise is mostly caused by loose connectors on the line and loose wiring screws. The most noise from the phone comes from the microphone noise, which can be taken under normal circumstances. Blow the handset to send a message. If the noise in the earphones increases, it means that the microphone has been burned out. Replace the microphone. If the noise does not increase, it indicates that the fault is elsewhere. You can swing the cord (the connecting line between the handset and the handset) and the cord (the cord connected to the telephone and the leather cord). Explain that the rope is intermittent, and the rope can be replaced. If the above conditions have eliminated the noise, you must open the phone and check whether the screws connecting the rope and the closing rope are tightened, and the microphone contact springs contact the microphone. Good or not, whether there is a virtual soldering of the circuit components of the transmission amplifier, whether there is dust accumulation on the contacts of the fork (fork spring) switch, whether the contact is good, etc. It is generally easier to eliminate such failures. ^[1]
