Polsen OLM-10 overview

  • 1Description

The Polsen OLM-10 Omnidirectional Lavalier Microphone is an all-in-one solution for recording hands-free audio to both channels of your camcorder or DSLR, as well as recording devices with a 3.5mm mic-level input that cannot supply phantom power. It is a self-powered clip-on electret condenser mic designed for accurate voice reproduction in home and video webcasting applications such as presentations, interviews, dictation, and corporate video. The microphone's small, 21-mm long lightweight body allows for discrete placement with the included tie-clip while its 20-foot long cable gives you ample distance from your recording device.

Featuring a 3.5mm dual-mono TRS output connector, the mic sends audio to both the left and right channels of your recorder. Thanks to its omnidirectional polar pattern, the OLM-10 provides a uniform response that will not cause the bass-boosting proximity effect common with cardioid patterns, while allowing you to move freely without off-axis rejection causing a drop in volume. The in-line power switch allows you to quickly mute the microphone as well as preserve battery life when not in use. A windscreen for reduced noise and plosives, 1/4" adapter, and LR44 battery are included.

Note: Not intended for use with smartphone or tablet devices.

    Polsen OLM-10 reviews

    OLM-10 Omnidirectional Lavalier Microphone is rated 4.2 out of 5 by 308.
    Rated 3 out of 5 by from good for the price I am using this attached to a Zi10 Playtouch for youtube and home videos. I like this lavelier microphone for my purposes. The mic quality in most video cameras is terrible to horrible. As far as I am concerned an external mic is absolutely necessary. The quality is not professional but is adequate for my needs.It improves the sound quality 100%. It is certainly good for speaking and instruction. If you are a singer or music professional you may want to invest in something stronger than this but for just speaking and regular sound capture this is good. The clip could be better but it is adequate.

    Rated 5 out of 5 by from Well Worth The Money!! I took a gamble on trying out this microphone. I wasn't able to find any reviews or sound sampling. Well, I must say, this mic does what it is suppose to do. Now the only things I have done with this mic are video interviews and ad promo for a political candidate but this mic has worked above my expectations. The only Con that I could think of is that the fact that there is no battery life indicator. So, besides the lack of a battery indicator, I think that this mic is WELL worth the money. My videos have been compared to the professional political company with very expensive equipment ($1,000+) and to just be in that conversation speaks volumes. Look up my examples on YouTube Keyword OnTheHillMedia and hear the mic quality for yourself.

    Rated 5 out of 5 by from HELPFUL USAGE TIPS FOR PRO MIXER INPUT, use the B/H HOASMFPM adapter to provide 1/4 unbalanced audio that WILL work on a pro mixer 1/4 balanced mic input. :) FRYING BACON STATIC NOISE, developed in my testing. solution, polish the battery edge and faces on a mildly rough cloth to remove invisible oxide, and if you are good with tools, carefully bend out the side contact to make it a firm fit. test this by hard tapping on the battery case and see if you have 'funnies' in the audio. a loose battery fit will suddenly inject 'bacon frying and static' into audio. making a tight/clean contact will stop/prevent that. with the adapter, tight battery fitting contacts, you will have a killer mic for little money. lastly, maybe they will make battery contacts much tighter and reverse the location of the battery holder to be at the mixer end so as to avoid battery jossling/noise, and a chance to fix it fast if you get unlucky and it happens. sorry about the runon and long wind, but i hope this and my last review are helpful in your using this GREAT LIL MIC.

    Rated 4 out of 5 by from You get what you pay for I purchased this mic so that I would sound better in my self-recorded videos using my Canon Rebel T2i DSLR camera. It has an extremely long cord and a clip for the mic so you can even use a decent portrait lens and clip the mic to your shirt. There is a box which houses a battery and an on/off switch, so it acts as a very weak amp. The muffler comes off very easily, so if you're not keeping track of it, you could easily lose it. Anyone who uses a DSLR for video recording knows that anything is better than the built-in mic. While this lav mic is certainly low-quality, it is still miles better than using the DSLR built-in mic while saving yourself some money. Just remember that you get what you pay for.

    Rated 5 out of 5 by from Buy this microphone You have stumbled across the best deal in audio technology, ever. I use this in the field as a freelance journalist. I was broke and tired of relying on others to borrow their audio equipment, so I bought this microphone thinking it was a gamble. Not at all. This microphone performs like a champ for field use, and the long audio cable wasn't as annoying as everyone says it is. I would just suggest wrapping it in a couple big loops rather than a bundle of small loops. Here is a link to a segment I did with this microphone. I plugged it directly into the camcorder: http://agourahills.patch.com/articles/malibulost-hills-station-celebrates-20th-anniversary-with-open-house-2600d1eb#video-7827714 There is a lot of ambient background noise -- but a lot of that was left in from other tracks intentionally to get the mood of the event.

    Rated 5 out of 5 by from Pearstone OLM-10 saves King David When the brass, woodwind and large percussion orchestra filled the 600 seat auditorium with raucous music for Honegger's King David, the speaking parts within our 100 member community chorus didn't stand a chance of being heard. All our funds had been spent on orchestra and soloists. But the hall had a sound system, and I had a guiet old field mixer. I also had experience with a predecessor of the OLM-10. I took a chance and ordered six. For less than $150, they delivered excellent sound from voices among the singers. The omnidirectional pattern made for evenness with untrained performers. Their self-powering and 20' cords made hook-up very easy. Congratulations Pearstone!

    Rated 5 out of 5 by from Yes, I would buy this again. The OLM-10 Omnidirectional Lavalier Microphone works perfectly with my Canon T3i. I just plugged it into the mic input, and it received sound from the mic instead of the built in mic just as it was supposed to. Great product. I am using it to video our preacher doing 10 minute lesson intro's for our small groups ministry. I forward the link to where I posted the video on out church's youtube channel, so each small group and watch the video when they are ready. The sound is very good. I am sure a higher grade would be even better, but I have a background in TV news, and this is plenty good enough for speaking. The 20-foot cord is awesome, too.

    Rated 4 out of 5 by from Good Mics So i bought a couple of these mics for a video project i had to do a couple of weeks ago. I needed better audio then using an in camera mic considering i had to film interviews and get good audio of myself asking questions and my interviewee answering them.I must say these were definitely worth the money, i was able to put two of them into a 1/8 splitter and plug that directly into my DSLR. I gotta say i was actually pretty surprised with this things performance, it gave me clean and clear audio in all my footage and the long cords were really helpful. Don't get me wrong it isn't the best mic ever, but for it's price id say it's definitely worth it. The only problem i had with them was getting the windscreens to stay on.
