The u256 sets a new standard for USB microphones offering excellent sensitivity, low noise, small size and ultra-low power consumption – all for a modest price. The components are housed in a slim and durable aluminium enclosure.

Like the well-known Pettersson M500-384 microphone, the u-series microphones identify as standard audio recording devices on Windows, OS X, Android, iOS and Linux. Likewise, they are compatible with most common sound recording apps and programs. Our microphones are naturally compatible with our own BatSound and BatSound Touch software. Some other recommended software for various operating systems include Audacity (Windows, macOS, Linux), Ultrasonic Analyzer (iOS) and Bat Recorder (Android).

Please verify the hardware/software compatibility and that 256 kHz recording is supported. Certain smartphones/tablets – particularly low-end devices – have been found not to support USB audio at 256 kHz.

The USB connector on the u256 plugs directly into a USB Micro B jack, becoming a small and portable recording unit. In order to connect the u256 to devices with other types of USB jacks or when space constraints make it difficult to plug the u256 directly into the USB jack, an extension cable and/or an adapter can be used. Such cables and adapters must be OTG enabled.
