Great Microphone for voiceover.

This being my first microphone for podcasting and voiceover, I am really enjoying it. The sound quality is great and the build of the microphone is just as good.


I NEVER got my package. I asked for a refund.


This works well for voiceovers.

my first microphone after headset microphones

if you think about buying this one don't think alot about it its the best microphone out there for its price.Crystal clear voice and with a little tweaking no background noise at all.

Purchased for a podcast and works perfectly

Purchased for a podcast and works perfectly!!! Sound quality is excellent and pairs nicely with two other (different branded) microphones since there are three of us in the podcast! Easy set up, heavy enough to stay put, great sound, and quick service. Although it is not recognized out of the box, after-sales team help me fix it up as soon as possible.

Versatility can't be beat

  • Even though it is born to be a dedicated recording microphone, but the simple connection does not give any dent to its commitment.
  • Being plug & play on Windows PC/laptop, Mac and Play Station console (incompatible with Xbox), it still has the presence of a decent condenser microphone.
  • Because of the recording-tended calibration, you do not have to bother with compression or EQ setting when fancying quick streaming on OBS, Twitch or Discord.  

Pull all features out of the bag for the best sound quality

  • Does the full metal construction mean only solid build quality to you? It is actually one of the crucial parts to help achieve good sound quality. Without a shock mount, it may still pick up some booming. But because of the heavy-duty body complementing with an anti-slide stand base, there will be less vibration head.
  • So does the height & angle adjustable stand, which gives the flexibility to set a perfect angle and distance. While those two factors is essential to get decent sound quality from a condenser mic.  
  • A volume dial on the front comes in super handy for quick adjustments on the fly of streaming or web conferencing. The combination with a headphone monitoring jack is the Ace up your sleeves for recording podcast or voice-over.  
  • Lacking a mute button and an output control is a pity, but it is justified by all the other features above and most importantly redeemed by the entry level pricing.

Raise your game with a live monitoring Jack

  • We present you with a no-brainer choice. You want a monitoring 3.5mm jack for plugging in your headphone to hear the audio in real-time or to find the best buffer size to reduce latency through trials and errors? 
  • Hearing exactly what you sound like to others is important for producing a radio show. Because you can just start self-regulating at the early stage of recording and thus get rid of time-consuming post-production.  
  • An output jack also means better connectivity. Hooking up with a computer or mobile (via) a USB adapter, then you can use an audio cable to connect the headphone jack with a camera or digital recorder for recording on various devices.   

Is the modern V-shape sound any good?

  • For either a professional condenser microphone or a consumer-level one, noise rejection is not something that can be made a big deal about. Because it is down to the environment. But a lower self-noise level that makes up for the overall noise floor is something that you can expect on this condenser microphone.
  • For either a professional condenser microphone or a consumer-level one, noise rejection is not something that can be made a big deal about. Because it is down to the environment. But a lower self-noise level that makes up for the overall noise floor is something that you can expect on this condenser microphone.
  • If you play an instrument a lot, the hollow recording will let you down a bit. But in some cases, the rounded low ends can gloss over the scooped sound.  
  • The 16mm capsule (2mm larger than the generic models) make your voice appear more engaged in front of the microphone. You do not have to eat into it for the radio podcast sound.
