Wireless On A Shoestring

There are a lot of times when a hardwired audio connection just isn’t going to cut it in a run and gun situation. And the first place most of us turn is to a good wireless mic setup. I’ve got an older version of this one from Sony, and it is rugged, reliable, with great sound.

The problem with the pro wireless units is that they are fairly bulky (you wouldn’t be carrying it around full time in a camera bag, unless you are seriously doing only interviews) and at $600, rather expensive.

TSA inspectors don’t like them because they look like part of a detonation system. Overseas, customs inspectors don’t like them because they look like something you could start a revolution with.  They’re strictly for bigger, professional productions.

Wouldn’t be nice if there were a reasonably priced ($179), tiny, lightweight (2 oz.) wireless system you could throw in your bag on fulltime basis to use for those travel gigs where you will occasionally find a character you’d love to mic up for a quick interview?

Well, there is, and for Sony users, it’s called the ECM-W1M Bluetooth Wireless Mic  and it’s a little godsend for those of us who want to travel light and unobtrusively, and still get decent audio in a variety of situations.  Canon makes their version and if you poke around, you may find others.

Size-wise, it’s a no-brainer…the little transmitter takes a AAA battery, the receiver connects to any Sony (including the RX100ii compact and several other compacts, as well as the A6000 and A7 series) that sports the Multi-Interface System (MIS).

This is the only real choice for off camera audio for those Sonys, like the A6000 and NEX 6, that sport the MIS shoe, but have no audio input, so video-shooting owners of these cameras should take special note of this Bluetooth option.

Now before we go another sentence into this, am I saying that this little setup is as good as a pro wireless system? No, not on your life. Let’s look at some of the disadvantages.

1. No volume control. Yes, Sony lets the camera take over on almost any audio accessory that uses the MIS system (with the exception of their big pro XLR adapter). The good news is that it doesn’t behave too badly and you don’t get wild fluctuations in gain if the subject should happen to stop speaking for a moment.

2. 100 foot, line-of-sight range. You’re not going to be shooting across football fields with the Bluetooth setup. And if the subject turns away from you at a distance, or walks into building while you’re still outside,  you’ll get breakup.

3. Hard to hide the transmitter. While the transmitter is about the size of a tube of lipstick, it is still substantially bigger than a little lavelier mic. And it can be hard to “hide” on your subject. The Sony model has a port for a lav mic, but most of my good lavs were just too “hot” and caused audio peaking.

Fortunately, I’ve been playing around with a new lav mic from our Australian friends at MyMyk called the SportsMyIt’s like a little lavalier on a 3″ flexible tiny arm with a heavy duty clip and it’s designed for using with POV cameras (you clip it to your helmet and you can narrate your viral mountain biking videos, etc. )

Well, it’s not as “hot” as my other lavs and it plays well with the Sony transmitter, and it makes it useful when you really want to hide the transmitter. And I’m happy to find a good use for this interesting mic, because my narration of the Actioncam videos of me having a night in the pub was just not helping those videos go viral!

 I used this system several times on a recent trip to Bermuda and so far have been very pleased with the sound quality. And all of my gear just sailed past customs inspection, with me playing my role as innocuous photo-weenie senior citizen going on vacation with Streep-like verisimilitude:-).

Of course all of this tiny gear wouldn’t be worthwhile if you needed gigantic headphones, and I’ve found that the Koss Porta Pro headphones are a great compromise between size and function (and apparently I’m not the only one because  video production guru Jem Schofield, of the C47 blog, is also a big Koss fan, and he knows his stuff).

So the Bluetooth wireless setup (with its cute little windsock windmuff for the transmitter), the Koss headphones, the SportsMyk and the mini-shotgun Smartmyk from MyMyk ride in my camera bag at all times.

They add hardly any weight, but a lot of audio capabilities for my run and gun travel videos.
