    Complete garbage Lav Mic - stopped working after 1month


    I will never buy another product from these guys. Should have known better. The bulk of Audio-Technica's equip is low-quality.

    Boise, ID


    I bought it - but its too freaking soft!


    Can't figure out how to make it louder


    Did not work with my iPhone 6


    I set the mike up as per instructions. It worked with a heavy guitar amplifier I have borrowed but refused to work with my iPhone 6, even when the phone was plugged into power. There's nothing on the box or in the online specs about the mobile phones with which it will or will not work. I clicked on a link on this Website which allegedly would have allowed me to ask a question about the failure to work but the resulting page came up with frame only--no capacity to ask a question. Hence I am forced to write this very negative review.



    Great entry-level Lavalier mic


    This little microphone is the best lavalier microphone in its class. It delivers good sound quality; much better than the built-in mic of a computer or a smartphone. The long cable allows producers to have flexibility in where they position their talent relative to the camera position. Users will find that It works well with cameras and smartphones. When using with computers, users will find that the sound from the mic is too low. The solution is to use a USB sound card, which boosts the sound to an acceptable level. While there are a LOT of USB sound cards on the market, the ATR2USB from Audio Technica is rock solid, and inexpensive. Are there better-sounding mics out there? Absolutely! But not at this price point. This is a wonderful entry-level mic.

    Audio level too low


    I tried this microphone on my phone, computer, and video camera. In all cases the audio level was far too low. I can't change the microphone level on my phone. Video recorded on the phone requires me to turn the volume up all the way to here anything. On Windows, I turned the mic level all the way up and encountered the same problem. On my video camera, a Black Magic Pocket Cinema Camera, I turned the mic level all the way up and was able to get better audio than on the other platforms, but there was far too much hiss and it still wasn't loud enough. I'll be looking for a different solution that has level settings on the amp.

    This is a joke


    I bought this thing to use with camcorders/dslr/phones, etc. can't seem to get any sound with any volume if any at all. so unpredictable, it was a waste of money



    Worst experience


    It only works the first time of use. Worst quality. A friend bought it and happens the same.



    Limited capabilities


    Here's the deal. It records much better sound than relying on your smartphone or built in mic on a camera. BUT, the issue I have experienced is the smartphone adapter that comes with it will not let me monitor my sound level when I'm recording with the lav mic. There is some issue with the jack that plugs into the phone ( in my case Apple 6+). I've tried different ear buds with different tips. So, you may not be able to monitor your sound recording with this package, but it does work well as a inexpensive mic for far better sound when using a smartphone (or DSLR).

    Excellent Entry Level Mic for Voice


    I did a lot of shopping around before buying this mic. I read a bunch of reviews and listened to quite a few audio samples before deciding this would be the best bang for my buck in terms of highest quality with the lowest cost. I've only been using this mic a short why, for completely amateur purposes, but I can honestly say that this mic records voice at a much higher quality than any other mic I own and built in mics aren't even in the same ballpark.

    Used it twice and it broke


    I was really excited about this mic and was looking forward to using it to record sound for video projects. I used it twice with the camera and was happy. It was a little hot, so I bought a digital recorder so I could adjust the input levels. When I plugged the mic in there was no sound at all. I replaced the batteries. Nothing. Tried it with my computer. Nothing. I have had the mic for 3 months, used it a total of two times. Very disappointing. Maybe I got a dud. I saw a lot of other positive reviews. Sadly, that was not my experience

    Yes it does.


    The screw for the clip fell off. What is the size so I can find a replacement?

    Hello, I've tried the ATR3350iS with my Samsung Galaxy S8 and it doesn't work properly. Despite using the adapter, the sound level is very low in the videos. Any solution ? Does this mic is properly compatible with Galaxy S8 ? Thx for your ansewer.

    can i use with video camcorder?


    Thank you for your inquiry. If your camera has a 3.5mm trs or trrs microphone input, yes it will work.


    I'm testing the Audio Technica ATR 3350iS with the Zoom H1n recorder. I can't get the audio high enough using this mic. When it's set on Auto level it hovers around -18 and only goes higher with loud noises. When I switch to manual level and set the highest level, the indicator bar it still only hovers around -18 for normal speech. Is there a known compatibility issue with these 2 products? Can someone offer a solution to enable me to increase the sound level? Please?


    Thank you for your inquiry. The output of the mic i mic level. you could have your input set to line level which would be expect a much hotter signal.


    I lost the clip and the black foam the cover the microphone Audio-Technica ATR-3350IS where i can buy the replacement ?
