USB Microphones
A USB microphone is the simplest route to a good recording: plug it into a computer or a phone and record, with no separate audio interface in between. For streamers, podcasters, teachers and musicians working from home, that simplicity is the point, and the differences between models come down to sound quality, controls, and what is in the box.
Two microphone models on this site carry published detail. The BM-U800RGB is a colour RGB lighting condenser microphone with a full specification sheet, including frequency response, polar pattern, sensitivity and gain, and two packaging options. Its detail page reproduces those figures. The CR-T15 and CR-T20 are described at application level: their feature sets are published, but they do not carry full specification sheets, so they get application-level pages instead of specification detail pages.
Feature-level models still tell a buyer something useful. The CR-T15 offers one-touch noise reduction, ducking and mute, voice changing, headphone monitoring and reverb control, and it connects to phones and computers with a USB-C cable. The CR-T20 adds switchable pickup patterns. What is not published for either model, such as power handling or frequency response, is not stated here.
Choosing a USB microphone starts with the room and the use. A streamer in a noisy room needs noise control and monitoring. A singer needs a microphone that handles loud passages without distortion. A teacher needs something that works the first time it is plugged in. The buying guide on this site works through those situations without ranking brands.
For the CR-T15, the company's own product title states that orders of 200 pieces for OEM production are accepted. That figure is published on this site for that model only. For other models, quantity and price are confirmed through the inquiry form.
