I've been keeping this as a sub microphone, but I no longer need it, so I'm selling it. I've used it two or three times, and it works without any problems. There is some staining on the box. All accessories are included. This is a discontinued product, so it's difficult to obtain. 【Clear, High-Quality Sound】Equipped with a special noise-canceling function! Effectively suppresses surrounding noise and white noise from computer equipment, and the unidirectional cardioid pickup characteristic clearly captures sound within a 130° range in front. The highly sensitive condenser core reproduces the natural beauty of the sound. *Because the K670B has high sensitivity, before using the microphone, adjust the input level on both the connected device and the microphone itself, gradually increasing from min to max until you reach a suitable volume. 【Glossy Metallic Construction】The body of the PC/PS4 USB condenser microphone, the microphone stand, the base, and even the volume adjustment button are all made of die-cast alloy. The metallic texture, robust design, durability, and stability are all combined! The high-tech feel combined with the jet-black color creates a luxurious feel! The microphone body weighs only about 293g, and the microphone stand (including the base) weighs about 350g. This provides a solid sense of stability. 【Highly Versatile Stand, with Replacement Screws】The product's metal connecting rod allows you to freely adjust the height of the microphone stand in two stages. The stable base prevents the microphone from tipping over or falling. The compact, space-saving design comes with rubber non-slip pads, allowing you to enjoy recording without worry! Replacement screws for connecting to an arm-type microphone stand are included, supporting standard arm stands for even greater convenience. (※Please pay attention to the installation direction of the replacement screws before connecting! Please be sure to read the instruction manual.) 【Easy to Use, with a Delay-Free Headphone Jack and Multifunctionality】Plug and play, simply connect it to the USB port of your computer/PS4, and it will be recognized immediately, allowing you to use it with ease. The microphone body has a headphone output jack, and by inserting headphones, you can clearly check your own voice and the sound from the computer without delay, and there is also an input volume adjustment button, perfect for gaming on Mac/PC/PS4, online calls like Skype, live streaming, home recording, telecommuting, and remote work! It is also suitable for narration, game commentary, Nico Nico Live broadcasts, YouTube video uploads, etc.
