New mics and clever parrots

Posted by IMR on 13 March 2010

LAST FRIDAY A new set of grief detectors arrived all the way from Microphone Madness in Florida. It’s nice getting things in the post that aren’t bills.

The mics are designated as MM-HLSOs, and you can read their specs on the budget headworn mics page here. They’re based on Sennheiser MKE 2 lavalier mics, and it looks like Microphone Madness may have altered them slightly, boosting sensitivity from 5mV/Pa to 10mV/Pa, while increasing their self-noise from 26dB to 29dB.

The mics are very small, which means they can be inserted in a Croakie mount, also supplied by Microphone Madness. What’s a Croakie mount, and isn’t it a bit irritating when product names have an -ie suffix? It’s a spectacle retainer made from two tubes of stretch fabric which slip over each arm of a pair of specs and converge at the back of your neck. The mics and their leads nestle unseen inside the tubes.

One of the nice things about being middle-aged is that while you can no longer wear shiny clothes, you can get away with a wider range of hats and with spectacle retainers, both ideal for stealth recording purposes, even if they make you style-kin to the tribe of antique dealers and racing pundits:

A first recording was made inside the Pembroke Arms pub in Primrose Hill. This pub is high-ceilinged and, like many modish London watering holes, has bare floorboards instead of carpet, producing the acoustics which are peculiar to that kind of place. The recording isn’t anything special, but the mics do a decent enough job:


The mics, their mount and delivery all came to $300. This is good value when compared with the price of a single Sennheiser MKE-2 from British-based retailers. The items was despatched promptly by Microphone Madness and came with an instruction leaflet. The Croakie mount does nothing to reduce wind-noise though, so it’s pretty much an indoor set-up. Later that afternoon the Sonic Studios DSMs with their handy windshield were used for a walk around the Stables market in Camden:


The MM-HLSOs were given a second go while wandering around the ground floor departments at Harrods:


I’ve always liked department stores, going back to childhood visits to an uncle who worked at Swan & Edgars in Regent Street near Piccadilly Circus. But there was one ritual at Harrods which, like Swan & Edgars, is now no more.

Harrods’ owner Mohamed Al Fayed is a parrot-fancier who keeps a large flock in his own private aviary. So the Harrods pets department was beefed up to include several different parrot species, some of them rarely seen in this country. An employee was designated as parrot-keeper, and most afternoons he put on a performance which drew large numbers of wealthy ladies of a certain age.

The parrot-keeper would begin moving among the cages, naming and describing each occupant, before opening one of the cage doors and putting his hand inside. A gaudy sun conure shuffled up his arm. Now he began to lay it on thick, telling his audience that the parrot was an emotional animal with “the intelligence of a four-year-old child”. On cue, the bird bowed its head, clucked quietly and the parrot-keeper tickled the back of its neck.

Sighs of sentimental pleasure rippled through the crowd, and one woman spoke for them all when she cried aloud: Ohhhhhh! That’s what he wants!

It would have made a good recording.

I’ve always fancied a pair of headworn mics… but as noone seems to make them here I’ve always been a bit cautious about spending that much money in the states.

Some very clear recordings!

Hello Martin, it’s a shame there isn’t a field recording cottage industry in the UK like there is in the States.

I’ve never had any problems buying kit from the US though, and would recommend Microphone Madness, no problem.

Sound Professionals SP-TFB-2 in-ear mics seem quite popular too, and they’re not expensive. Ollie Hall uses them for some of the recordings featured on his blog.

Lots of mic model spec comparisons on the Budget Mics page here.

How noisy are these mics compared to the DSMs? Do you notice a major increase in noise? These recordings make it really hard to tell. I am trying to get some mics for classical recording and I have been looking at these MM mics as an option. 29db seems kinda noisy…what do you think?

Hello Brian, Sonic Studios make and sell one model, the DSM-1S/H, which has a stated self-noise level of <26 dBv. The other models I guess to be in the low 30s.

The MM-HLSO doesn’t have an equivalent to the Sonic Studios windshield, which limits their use to indoors and very still days outdoors.

I’ll be making a recording with the MM-HLSOs on Monday evening in concert-hall-like conditions, so that should you give you some kind of reference.

Posted by IMR on 18 April 2010

Oh great! I can’t wait to hear the MM-HLSO’s in action. These mics are my #1 choice at the moment because they appear to be the best compromise between quality and price.

BTW I was on the phone with Microphone Madness on Friday and they said that they do not modify the MKE-2. They get the bare capsules without any wires and terminate them with Mogami cables. The MM-HLSO’s self noise should be <27 db as stated on the Sennheiser Data Sheet.

Please post a sample of your concert on Monday night. It will really help me make up my mind. What are you going to tape?

Posted by Brian on 18 April 2010

It’ll be a recording of a male choir singing Vespers in Westminster Cathedral, so hopefully should give a good approximation to concert hall conditions. Thanks for putting up those spec details, Brian. You’d get better quality at the same discreet size with a matched pair of DPA 4060s, but that’d involve a big price jump upwards (around $1,000 from Core Sound).

The recording is on this page.

No EQ has been applied for the time being.

These mics sound excellent! I like them better than the DSM’s. How close were you to the choir when you recorded this? To me it sounds a little distant. If it is possible, I would suggest that you position youself in the first or second row (15 feet or so) to get optimal mix of ambiance and direct source. If I want to get picky, I hear too much reverb from the Cathedral and not enough direct source. I purchased these mics today and this recording helped make up my mind. Thank you!

You’re right Brian, the recording really could have benefited from being made closer. However, the front seating rows were nearly all occupied by worshippers by the time I got there. Also, I must admit to being unfamiliar with the form of the service, and this made me reluctant to press forward too eagerly.

Glad to hear the recording was helpful to you. I do think the MM-HLSO with its discreet Croakie mount is a very good value-for-money setup for indoor recording.

Hi there,

As IMR states I can indeed vouch for the Sound Professionals SP-TFB-2 binaurals.

You can find the spec and further info on their site - here: http://www.soundprofessionals.com/cgi-bin/gold/category.cgi?item=SP-TFB-2&type=store&template=specifications

I use them on the vast majority of the recordings on my blog BinauralDiaries.
