A studio to go

The SC 420 USB Set is a complete and easy-to-use package aimed at budding audio engineers, home-studio enthusiasts, and podcasters alike. A simple USB connection and your recording voice are all you will require to get started! It also features a useful headphone output for zero-latency monitoring. A foam pop filter is also included to guard against plosives, as are a suspended shock mount (to minimise vibrations and handling noises) and a round table stand. The whole package is very attractively priced, providing a professional-grade audio recording solution for the many.

Rich sound

Large-diaphragm microphones such as the SC 420 USB are valued for their high sensitivity and accurate rendition. In addition, their proximity effect is more pronounced than that of small-capsule mics – in other words, the closer you are to the microphone when speaking or singing, the warmer your voice will become. The same effect will apply to other sound sources such as guitars and pianos. Large-diaphragm microphones are extremely versatile, and every studio should have at least one. Podcasters will also appreciate the richness and “radiophonic” quality of their sound.

Plug & play

The SC 420 USB eliminates the need for an audio interface, preamp, and all associated cables – which is ideal if you’re impatient to get started, or on the road a lot. Thanks to its plug & play functionality, the microphone works out of the box with both Windows and Mac operating systems without needing to install any drivers. The integrated headphone output allows you to directly monitor the input signal without any latency. The SC 420 USB is primarily aimed at podcasters and singers who want to record in a home-studio environment, which is why the package includes a pop filter, a table stand, and a shock mount.

About the t.bone

Since 1994, the t.bone has been one of Thomann’s in-house brands, and its name can be found on devices such as headphones, wireless systems, in-ear equipment, and various microphones and matching accessories. “the t.bone” products are made exclusively by renowned companies who also manufacture products for other well-known brands. This provides a clear advantage: Brand-quality products at very reasonable prices. And word gets around: One in seven Thomann customers has already bought at least one product from the t.bone.

A saviour in many situations

The frequency response of the SC 420 USB features a slight bump at around 10 kHz, adding a subtle yet recognizable shine to the voice that is often found in professional recordings. In addition, the SC 420 USB has a cardioid polar pattern, which effectively attenuates unwanted sounds and interference from its back and sides. Room and ambient noises are thus kept to a minimum, even if the home studio does not have the proper acoustic treatment.

Good entry level microphone
Triodes 07.12.2020
I read a lot of comments about the headphone jack being to loud. This can be adjusted in the software on your computer!
On both windows and mac the mic registers itself as both an INPUT and OUTPUT device.

On windows the input device allows only the configuration of the mic volume going to the applications. But the output device allows you to set the level of PC sound going to the headphone jack AND the level of the mic going to the headphone jack. They can be set individually and the mic pass-through can even be muted altogether so you won't hear yourself anymore!

On mac you can adjust the mic through the MIDI application. I have not found a setting to adjust the pass-through volume of the mic to the headphone jack, but you can mute the pass-through using a checkbox.

Go try for yourself :P


This microphone gives some absolute bang for the buck. The sound quality is good. It will pick up most sounds in the room though, so it won't be suitable in noisy environments. As soon as you move yourself away from the mic the sound will get more 'hollow' and will lose much of it's low end, but that is to be expected.

I have had the mic working on windows, mac and even android using a usb-c to usb-a otg adapter.

The build quality is not outstanding, but for this price I would rate it very good. The mic itself is lighter than I would have expected. The metal casing seems rather thin, but it is sturdy enough. The stand is perfect, it's heavy and has soft padding at the bottom. It can be easily moved but its weight makes sure it won't move by itself.

The mute button is very useful, but it's click when un-muting is picked up by the mic very badly to the point of clipping. They should have used a non-clicky button in my opinion.

I'm using this mic for discord/gaming and work conference calls. I'm not wearing headphones during these and I get no complaints about people hearing themselves, so the echo seems minimal. I would expect others to be able to hear my keyboard, but they haven't complained about it yet. I do often mute the mic using the button when I'm not speaking though.

One last thing to note is that the inside of the metal grating holding the diaphragm is lit up by a bright blue led. I don't really need this and it can be a tad annoying when the room is dark. I simply put the foam cover over it and now it is barely visible.

All things considered I would definitely recommend this microphone if you're on a budget.


It's a saviour!

As a pro, I own some great mics from Shure, AKG and Neumann.
Apart from the studio, I do Music Production lessons and seminars which turned out to be internet only (thanks Covid-19) and got really tired of having preamps or at least a soundcard open, get the mic out of the case, xlr cables etc....
I wanted something to help my voice get heard and super easy to work with, no matter if I'm with my laptop or the desktop, home or in the studio...
Well it does the job! And this is what counts the most!
-plug n play
-well build
-great mini stand
-decent sound for internet calls and seminars

-in that price range and for what it offers, I can't find any.

DON't get it if you want to record for your next single or album.
GET IT if all you need is a mic to help you sound decent in the internet, podcasts and video tutorials.

I would happily spend 50€ ONLY for the great case, the mic foam, the popfilter and the mini mic stand. :)

Was looking for a budget USB Mic for Podcast. Hit jackpot. Amazing mic. Completely satisfied after a lot of failed attempts.
- Amazing packing and box
- Easiest installation (plug and detect)
- Never thought t mute button on mic would turn out to be such a great feature!!
- Headphone out on the mic.
- Almost inaudible white noise.
- Great recorded quality
- Can also be used as instrument mic for live stream.
- Awesome microphone stand with great wt support.
- double Pop filters

Honestly couldn't find any mentionable ones yet.

I wanted to buy SC 430 because of the on mic gain and headphone adjust knob, but couldn't get it as it was not in stock. Surprisingly, I don't regret it anymore. I consider myself a winner getting it, so I would recommend it over any other USB Mics available!

This set has proven to be very sturdy and the sound quality is good. I did find the metal post on the stand to be slightly longer than I wanted, as it raised the Mic above the level of the acoustic shield I had bought to go with the kit, but I happened to have a shorter post handy.

The mic is identified without any issue by the Ubuntu or Pop!_OS flavours of Linux, although it is also detected as a speaker so I had to pop up the audio settings and swap that back to the built-in sound card when plugging the mic in. If this were a significant problem then a quick configuration hack would make it go away, but it's trivial to just click the correct option each time and I usually leave that window open during video calls anyway in case I need to tweak volume settings so it's no extra effort.
It would get 5 stars if it correctly registered as a mic only and not speakers.

The pop-filter is a little too elastic so it can be fiddly to get in the right orientation and place, but that's just how most pop filters are, it's not a specific problem here.
