Extensive expansion options

Thanks to Dual Channel technology and the ability to connect up to 10 devices simultaneously, this set will be an invaluable support during interviews, online workshops or live broadcasts on multiple platforms at the same time. You will find 2 transmitters and 2 receivers here, and if necessary, you can buy more microphones. This solution is a real game changer if you are streaming on Twitch and TikTok at the same time, for example. It also gives you even more freedom, whether you are conducting interviews as a duo, recording a podcast with a guest or organising training courses for a wide audience.

Broadcast sound quality

At the heart of every transmitter in the Ulanzi HM2301 wireless sound kit is an omnidirectional microphone (360°) that captures the full spectrum of the voice in 48 kHz/16 bit quality. In practice, this means that listeners will hear every nuance and emotion. This set is ideal for field recordings. It is also perfect for conferences or recording extensive vlogs.
Built-in special modes
You don’t have to worry about the acoustics of the place where you are going to record. The HM2301 offers three special built-in modes that help you deal with various inconveniences. These are noise reduction, microphone muting and a reverb effect. There is also a 4-step volume control on board. With a quick click, you can adjust the sound to the conditions in which you are currently recording. This makes it easy to switch from quiet conversations at home to loud outdoor events, always maintaining a clear and crisp transmission.

Light, compact and always at hand

Each transmitter weighs only 12 g, so you can attach it to your collar, jacket lapel or pocket and forget you’re wearing it. The set also includes a practical case, so your microphones and accessories are always ready to go. If you often change recording locations or want to be discreet during live appearances, you will certainly appreciate the mobility of the Ulanzi HM2301 wireless audio transmission set.

Up to 30 metres range

Enjoy uninterrupted work in the great outdoors or on a large film set. The 2.4 GHz signal will ensure reliability and a range of up to 30 metres. You don’t have to worry about loss of quality or delays during a live broadcast, webinar or dynamic recording session. With the Ulanzi HM2301 – USB-C set, you have complete freedom of action, which translates into even better work results.

Plug & Play – Switch it on and get started!

Forget about time-consuming configuration – just plug the receiver into the USB-C port (or use the included Lightning adapter), turn on the transmitter and you can start recording right away. When the microport starts to run out of power, you can use the USB-C port – the device allows charging while working. The built-in 130 mAh battery will give you up to 5 hours of continuous recording, so even longer audio-video sessions won’t beat you.
