    Avoid this Product


    Sounds great, but doesn't last long -- it's broken after less than 2 months. I've tried to connect it via USB with multiple cables across multiple computers and it just isn't being recognized. This seems to be a known problem with this mic but they're still selling 'em.



    Great mic, bad USB connector


    I've been very happy with this mic for the last six months. I've had it set-up in my office on a swing arm in the same spot since purchase. I recently moved the swing arm mic stand and had to disconnect the USB cord from the rear of the mic. Now the mic doesn't work. I tried the same USB cord with my old mic, and it still works fine. I used the ATR-2100 for about 8-15 hours a week, and performance has met my expectations. I'm disappointed in the flimsy connection for the USB. I will likely start the warranty process this week.

    Works GREAT and sounds GREAT!


    I bought this microphone after reading very positive reviews on some voiceover sites. They compared it very favorably to the Hyle PR40. So, it was an instant sell. It sounds, in my opinion, better than a Shure sm57 and it can do the same jobs. It feels solid! It works GREAT for recording in Reaper. I am very happy with the mic. I liked it a lot more when I bought it for under $40. but at it's current price, it's still a good product.

    This a great mic, especially for the price


    This mic has lasted me for 2 years with no problems. The audio quality is very good but the audio is not the absolute best because it is very good for the price. I use this for commentary and for singing and I have had no problems. The only thing I would have to say about it is that you have to be fairly close to it to get good volume. Also, it is a bit bass-y from my experiences but it should be fine as it isn't too bad.

    Mostly satisified. Good product.


    Used for over a year with no issues. Mostly use for web conferences. Voice quality is high. Not sure what it's frequency range is as I use mainly for voice. Others reviews say USB failed but I haven't had this issue. If USB failed after 3 uses, probably a manufacture defect. I would return and then write a review.

    Please never buy this product ever....


    I bought this product for my Tutorial recordings. I ordered it from US, as it was not available in stock in india. I got it after long wait. In only two to three uses, the USB no longer works. Its detects the microphone etc. But no sound at all while recorrding. I searched for drivers, but no drivers or updated drivers on net anyhere. On this website also no drivers at all. I tried on windows 8, windows 10 and Mac Book Pro with Mac OS X



    Works well thought USB


    I use the microphone for recording voice for video, podcasts, etc., and it has been working well for about 6 months or so. It works well into a Mac running MacOS 10.11, simply appearing in the Control Panel. I use a wind cover and a spit shield, and tend to deploy it on a floor stand to get the height right. For me, the included desk stand is too low. I have had no problems with the USB connection, which is the only one I use. I do use a bit of bass boost on the final product, and you do need it to be quite close to get good volume; about a fist length away, so try to restrict your gesticulations! Overall, good value for money.



    USB Dead After Three Uses


    It sounded good while it worked but died after just a few uses. Seems to be an issue with the USB port as I have tried multiple cables to no avail.



    Stay Away from this Mic


    This thing is junk. Had to send it back once to get a component fixed after 2 uses. The turnaround was good on the mic being "fixed" and returned but it still doesn't work correctly. Windows does not recognize the mic.



    USB feature unreliable/broken


    I bought three of the ATR2100-usb mics in March 2014 for light usage (podcast recording). When I use the XLR output and go through a mixing board, these mics work fine; great tone, noise free, etc. The problem I have is when using the USB connection. For the first six months of very occasional use (twice monthly for up to 20 minutes), the mic worked fine. But no more. First one mic became unusable on my Windows 7 laptop, displaying the error "usb device not recognized". The other mics worked fine, until today when mic #2 "broke". (I subsequently tried the "broken" mics on my mac, same result.) Now I'm left with only one of the original three mics able to be used via the USB connection to the laptop. At this time I cannot recommend the ATR2100-USB.

  • Q & A

    Where does the microphone get its power, the USB plug or the other cord? Or is it battery powered? I just want to make sure I'm not going to have any problems because I'll be using it for the first time at a live event where I'll be singing. Thanks!


    USB Bus power.


    Is there a way to fix this mic after it gets the USB device not recognised error, or is it dead? I haven't used even used it that much and now it won't work. It looks like this is a pretty common problem. If it can't be fixed, why are you still selling them?


    You may contact Audio-Technica Australia for further assistance.


    Hello, I have just recieved my new ATR2100, I have a macbook and when I plug in the USB, the computer does not recognize the microphone, and does not appear in my sound settings, any idea what I could do or what I am doing wrong?


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    Can i use 2 of these usb mics at the same time?


    Thank you for your inquiry. That depends on your OS.On windows no, but on a Mac using aggrate device set up it may be possible.


    When I plug in the mic to my computer through USB, I sometimes have a high sensitivity and sometimes a low. I never change any settings and haven't found any to fix this. How do i keep it at the lower sensitivity. (I don't appreciate hearing everything outside like it is at the mic.)


    Thank you for your inquiry. Please contact our Service Department at 330-686-2600 ext. 5003. They would be happy to help you.


    All of a sudden a BUZZING noise comes through calls and live broadcasts. Any suggestions to relieve that ugly static sound? Please I use it through a Berringer .XENYX Q802 USB Thank you for any help you have,


    Thank you for your inquiry. Connect headphones to the mixers headphone output. If the buzz is not there, there may be an issue with the application you are using. If the buzz is present, try another microphone cable. If the buzz is still present please contact our Service Department at 330-686-2600 ext. 5003. They would be happy to help you.


    Is there any way to use this mic with an iPhone 6s? Wondering if there is a way to use either USB or XLR connection to my iPhone when I'm at a conference and need to be mobile.


    Thank you for you inquiry. We do not have such an adapter. Check with They may have a cable for doing this.
