I bought these Tonor TM20 Omnidirectional USB Conference Microphones to use for a homemade digital assistant project. They work pretty well, but there some requirements I discovered that made another product a better fit. They are versatile and easy-to-use microphones designed for conference calls and online meetings, and would be ideal in a small business environment. The omnidirectional polar pattern ensures clear audio capture from all directions, making it suitable for various settings. My issue was that they would work well within the range of use around a conference table, for instance, but were less effective several feet across the room. This microphones, coming in a lot of 3, are a reliable choice for improving your computer's audio capabilities and enhancing your communication experience. Two of the units come in original box. All 3 have their USB cables included. There is 1 copy of the user manual.
