A second microphone or a guitar plugs in at the back: two channels recorded to a computer, tablet or phone with no external interface. 48 V phantom power, +60 dB of gain and latency-free headphone monitoring.
•Cardioid dynamic capsule, tight on the voice
•Plugs in over USB-C to a computer, tablet or smartphone
•Built-in audio interface: XLR combo input and 6.35 mm jack for a second microphone or an instrument
Discreet on a jacket lapel, the lavalier microphone leaves the hands free for a conference or an interview. The bodypack transmitter runs for over 14 hours on two AA batteries.
•ULM18 lavalier microphone with a cardioid pattern, which limits feedback
Close-miked radio or podcast voice: the pop filter holds even on a whisper, and the shielding cuts hum from screens and power supplies. Two switches adjust the bass and the presence.
•Uniform cardioid pattern, off-axis sound rejected without colouration
A touch LED strip that acts as a live level meter and mutes the pickup with one press, among 16.8 million colours. Headphone output for monitoring, an all-metal body and an adjustable yoke for a stand or a boom.
No accessories to buy separately: the pop filter and the shock mount are housed in the body. Pickup concentrates on the voice in front of the grille and connects over XLR, with no phantom power to provide.
Studio, podcast or voice recording: it connects over XLR to an audio interface or a mixing desk. Its 80 Hz low-cut filter keeps room rumble out for a clean voice from the first take.
•XLR connection: requires an audio interface or a mixing desk
Chrome-plated with light blue trim, it catches the eye as much as it holds its place: the tight front pickup rejects sound from the sides and pushes back feedback. The capsule is shock-mounted, free of handling noise.
•Dual output: USB-C to the computer, XLR to a mixing desk or an interface
•Built-in headphone output for direct monitoring while recording

Two gain steps, +18 or +28 dB, delivered by the on-board preamp: any interface can keep up, even on a soft voice. A switch bypasses it to return to the original behaviour of the SM7B.
•Built-in preamp: +18 dB or +28 dB of extra gain, with no background noise
•Bypass switch to return to the original behaviour of the SM7B
•Preamp powered by the 48 V of an interface or a mixing desk
Fourteen hours of operation on two AA batteries and up to 100 metres of freedom around the receiver. The automatic scan finds a clear frequency and a single press selects it: everything is ready in seconds.
Ten minutes of charging give back two hours of singing, and you keep singing while the microphone recharges on the speaker. Up to 20 hours of battery life, 30 metres of freedom with the dongle, built-in pop filter and shock mount.
Discreet on a jacket lapel, the lavalier microphone leaves the hands free for a conference or an interview. The bodypack transmitter runs for over 14 hours on two AA batteries.
•ULM18 lavalier microphone with a cardioid pattern, which limits feedback
Ready to use as soon as it is plugged in: no driver or software required, it works with Discord, OBS Studio and XSplit. The stand detaches to move onto a boom arm above the desk.
•Supercardioid pattern, tight on the voice and closed to keyboard noise
•Direct USB connection to the computer, no audio interface needed
A large diaphragm that flatters the spoken and sung voice, and a 144 dB SPL handling that copes with a guitar amp or a snare drum. It connects to an audio interface or a desk able to supply +48 V.
Chrome-plated with light blue trim, it catches the eye as much as it holds its place: the tight front pickup rejects sound from the sides and pushes back feedback. The capsule is shock-mounted, free of handling noise.
