【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. [New In Ear Features Added] Solidcom C1 Pro is Hollyland's first simultaneous two-way wireless intercom headset system with dual-mic environmental noise cancellation (ENC) technology. While maintaining the functionality of the C1 Pro, users can connect their own 3.5mm earphones and use it around their neck using the included USB-C to 3.5mm conversion cable. Like the existing series, this headset system is extremely lightweight and easy to use, making it ideal for production teams working in loud environments where good communication skills are essential. [Interchangeable with Solidcom C1 and C1 Pro series] The new Solidcom C1 Pro In-Ear version is not an independent new product, but can be used in conjunction with the previous Solidcom C1 and C1 Pro series. Additionally, the master head label has been changed to orange, and the remote head label has been changed to green, making it easier to distinguish them even when placed together. Note: The conventional C1 and C1 Pro series cannot use the included USB-C to 3.5mm conversion cable. [Full Duplex Wireless Intercom] The Solidcom C1 Pro series wireless intercom has separate transmitting and receiving lines, allowing it to send and receive voice data at the same time, and as a work intercom, it can be used for communication (speaking and listening) at the same time. Additionally, it consists of a group of headsets that work without the need for an additional belt pack. Solidcom C1 Pro Series enables real-time, hands-free communication within teams of 2 to 9 people. It can also operate in the 1.9GHz frequency band with line-of-sight distances of up to 350m/1,000ft. The Solidcom C1 series wireless intercom also has a plug-and-play design that allows you to use it right out of the box. 【ENC Noise Cancellation】Solidcom C1 Pro earphone version utilizes dual microphone ENC noise cancellation technology, which can reduce the surrounding noise by 20dB. The frequency range is 150Hz-7kHz, the sample rate (SPS) is 16k, the signal-to-noise ratio (SNR) is over 70dB, and the distortion is less than 1%, making it possible to smoothly conduct clear team calls even in noisy environments, making it useful in a variety of situations. [Easy to switch between full-duplex calls and PTT calls! ] You can switch between the PTT method (the microphone is on only while the button is pressed) and the hands-free full-duplex call method (no need to press the button). For example, when you are working with both hands and cannot press a button, you can make a hands-free call by simply speaking into the microphone, which is a very convenient feature.
