Rated 4 out of 5 by from Good investment for making music! I used this device to make music through BandLab. The sound from this baby is good and clear! When looking at the photo online, it looks bigger than what it actually is. It is very sturdy and professional looking. Really, my only complaint I had was I had to buy an adapter to connect it to my Macbook. I couldn't find anywhere in the paperwork or on the box where it indicated an adapter might be necessary. So I was a little bummed when I go to hook it all up, only to find out I needed to go back to the store to buy one. For the money, this is a really good investment.

Rated 5 out of 5 by from Excellent mic This microphone is fantastic for constant Zoom meetings (the primary reason I need it). The sound is clear with no interference, and when I used it for and recorded a Zoom call, it sounded like I was in the room instead of using a microphone. It's good enought that I would use this instead of a production studio for a video lecture if I set up a green screen behind me. The form factor is also nice-- it fits well on my Varidesk so that I can easily use it whether I am sitting or standing, and it's much more compact and looks nicer than the larger, older mic I had been using. I haven't tried using the omnidirectional setting in a conference room with a large group yet, but I expect that to work well based on the office performance so far.

Rated 4 out of 5 by from Tiny, perfect for gaming and work, good sound While looking for a small, practical solution for a microphone which is easy to travel with and useful for different purposes, I found this product fitting perfectly for my needs. I also own a Røde High-Quality mocrophone for streming purposes, but this one is really sturdy and not fitting my requirements when on travel or for video conferences in my working environment. Using the microphone now for several weeks, I can tell that the sound quality is really good, and I can really recommend the product. I like the state-of-the-art USB-C connector and the well-designed LED light. The mic itself is pretty handy, light and has a plastic feel to it. However - as it is designed in a very balanced way between cost-efficient but still high-quality look, that's no problem at all, as you do not touch it permanently. Please note: I got this product for testing purposes, but later on I actually bought it as well, as it is fitting my requirements pretty well.

Rated 4 out of 5 by from Well done The microphone is small and compact so it doesn't take up much space. The simple, but fancy design is great without any frills. It can be easily connected to the PC and is easy to use (Plug and Play). An additional software is not necessary. The sound quality is more than sufficient for recording YouTube videos, for example. The fact that you have the mute switch directly on the microphone is a clear plus. The lighting also signals you what "stage" the mic is in, so you always know when the mic is recording. Unfortunately, there is no option to adjust the microphone in height. But you can tilt it with the stand that comes with the product. The jBL Quantum Steam was sent to me as a product test.

Rated 5 out of 5 by from Solid little mic with some great features. I got the quantum stream a few weeks back and it has worked out really great. I use it daily for online meetings. The ability to hear in the headphones how I sound on through the mic has been really helpful. The green and red light under the mic lets me know clearly if I'm muted or not. Usb cable is more than enough for any of my needs and its a sturdy braided cord. I have taken advantage of easily being able to switch from cardioid (monodirectional) to omnidirectional setting with just holding the volume down. I also appreciate the solid metal base of the unit.

Can you use the microphone with speakers or will it create a feedback loop?

Asked by: Dan63
Our JBL Quantum Stream can be connected to a speaker through a 3.5mm to 2.5mm Aux cable. When using the speaker, please make sure to keep the mic away from it and keep the volume at a mid-level to avoid feedback.
