Ask Slashdot: Wireless Microphone For Stand-up Meetings?
rolandw writes We have daily stand-ups and normally there is at least one person missing from the room. We relay via on-line chat but the sound quality is rubbish. The remote person sounds great via our speaker when they use a headset but they can't hear what is happening in the room. We need a wireless mic that copes with a large echoing room and will stop feedback. Can you recommend one? We're not an over-funded start-up so don't have an unlimited budget...
Microphones aren't magic like that. :-/
Pretty much every company ever has already solved this problem with polycom (or similar) conferencing phones(ranging from a few hundred dollars on up)
http://www.polycom.com/product...
Also conference phone numbers like Webex at all so lots of people can call in, if you need that sort of thing.
This is not a new or unsolvable problem, this is "standard office gear" since the 1990s.
Get one, mmaybe two real wireless microphones from Shure or someone like that -- think "audio equipment catalog", not "computer equipment catalog". Get the cables to hook the base station up to standard microphone input. Pass the mic around to whoever is talking; it doubles as the "currently speaking" token (and you only have one person at a time talking at standup, right?). Make sure you have lots of spare batteries (presumably rechargeable) in a convenient location.

1: Stop doing "stand-ups".
2: Use a wired mic (or several). Alternatively, use the wired phones you likely have at your desks.

What about equipping all meeting participants with a wireless headset (headphone with mic). A base station in the room would connect to each headset, and transmit audio to remote participants. I also work for a company with many remote employees. When all meeting participants are at their desk using headsets, people are easy to understand, but as soon as some of the meeting participants are in a conference room with a speaker phone it becomes very difficult to hear people. As a result we do a lot of meetings from our desks even though many of us are in the same building and could benefit from a face to face meeting.
Does any device like this exist at any price?
Is your room a natatorium, or a broom closet? How many people? Around a table, or classroom seating? Have you tried a proper conference room phone (not a regular speakerphone)? Is your phone system analog, digital, or IP (for the latter two, the solution may depend on the system in use)?

How about just tell them to be in the room when you do the standup? This solution is simple and costs absolutely nothing.
Kinda difficult when that person isn't even in the same country.
You don't need a new mic, you need better cables.
I recommend Monster or Audioquest for the ultimate in high fidelity audio performance.
Personally I'd go with the CX3000, it does POTS, SIP, and USB connectivity and you can use the expansion microphones which is huge if you have more than a few people on the call.

The Jabra Speak 410 is also an excellent USB speakerphone with feedback suppression. Works well with Lync on Windows or Mac, in my personal experience. This would require someone bringing their laptop into the conference room just to run the VoIP app of your choice, though, but is likely to be a cheaper solution than any Polycom phone.

Unless your employees live in the same building as your office, there's a non-zero cost to having everyone in the office for meetings. At my office, even though employees are all "local", depending on traffic it can take up to 2 hours for some of them to get to the office.
What you are looking for is a "boundary microphone", also known as a "Pressure Zone Mic (PZM)"
If you absolutely must do it the way you are doing, just buy a used Polycom and be done with it.
Physics is nothing like religion. If it was, we'd have an easier time trying to raise money!
either get the microphone closer to the person speaking (e.g. handing a microphone around) to tune out most of the room, or make the room sound better (curtains, reflection cancelling wall panels, ...).
Get management to pony up for real AV gear. The problem is your gear is garbage and not designed for the use. There is no magical CHEAP thing you can buy.
Now get a biamp or BSS DSP and 4 boundary mics hanging from the ceiling on some 18" diameter glass plates... I can make a meeting room cover all voices in there perfectly for video and teleconference.
Do not look at laser with remaining good eye.
A $10 microphone won't be much good for a variety of people. OTOH ask where is the signal degradation happening? If you don't know then find out.
I was recently looking for a solution to a similar problem; speech-recognition from any spot in a living-room with a air-conditioner and lots of PC-fans running 24/7.
The only thing I could find that that was not a conference phone but still had speaker-tracking and echo-cancellation was this:

4. PC/laptop microphones suck. I don't know why no one bothers to test them to the same level as your average cheap dumbphone speakerphone. They pick up all kinds of system electrical noise, ...
The problem usually isn't the microphone. It's the way it's wired (per the standard) and the way the desktop/laptop is powered.
PC microphones are wired UNbalanced: They have a signal and a ground wire, rather than the + and - signal wires and everything-but-desired-signal cancelation of the balanced wiring setups typical of professional microphones.
Laptops typically use power supplies that are not grounded, so they don't require a three-prong outlet. This usually ends up with the stray capacatance to BOTH sides of the line wiring capacitively coupling equally to the laptop "ground". That means the "ground" of the laptop is at half the line voltage - about 60 volts of AC (a rotten approximation of a sine wave plus lots of other junk it picked up at an assortment of frequencies). The capacitance is substantial - not enough to shock you if you touch the laptop and ground, but enough to feel a buzz if you rub your hand lightly across a "grounded" metallic part of the device.
Plug in the unblanced microphone and hold it, put the headset on your head, or just leave it sitting on the table. The "ground" is at 60V and you are driving maybe a couple MA of it down the shield wire. The voltage drop of that current (along with any other pickup) adds straight onto your audio input. The best microphone in the world will perform horribly if hooked up this way.
Try this: Unplug the laptop and let it run on battery. Notice how almost all of the noise disappears. You can also get rid of most of the noise by tying a decent ground onto the laptop. (Unfortunately, many meetings last longer than the laptop batteries...)
Plug in a VGA monitor with a three-prog power plug, which grounds the case of the laptop via the shield and the two hold-in screwd. I've done that without actually hooking up the monitor (which would have disabled my laptop screen) by adding a couple of the nuts scavenged from another DB connector as conductive spacers so the actual signal pins are not quite into the plug. And done this on a docking station, so the laptop headset was quieted when the laptop was docked, even though I used none of the docking station features except the power input.
Make a second cable with a three-prong plug to bring a ground up to the laptop. Green wire from the third pin to a screw into or clip onto such a chassis ground point.
Or bypass the problem completely by using a USB microphone. These digitize the audio right next to the microphone proper, with everything floating at the same voltage so nothing substantial is picked up betwen the air pressure sensor and the A-D converter.

I'm almost always the only person joining our team meetings remotely. I could barely hear people in the room. I searched for a hardware our small startup could afford. I decided to give a try to Highfive. The wide camera video feed is a nice plus to an outstanding sound quality.
Any of the Sennheiser or Shure wireless packs.
Countryman E6 type headset. Best every
For $700-$800+ you've solved the microphone problem. Look for used, maybe save half.
Maybe a Shure BLX14, $300
An Audio-Technica System 8 might satisfy your needs, $200 +/-
Then go fix your speaker placement and EQ the room. The Countryman likes a slight cut at 600Hz for vocals, choose the capsule cover carefully. The A-T mic I don't know well.
deleting the extra space after periods so i can stay relevant, yeah.
We do daily stand-ups between 2 locations. At one end which is a large office, we have a MXL AC404 USB conference microphone on a table that people stand or sit around. People around the table sound great, and it is omnidirectional, so it doesn't matter where people are. If someone goes off to scribble on the whiteboard and is 8 or 10 feet away from the mic, you can hear him or her, but it doesn't sound as good because it gets a little soft. If you keep an eye out on Amazon, or use camelcamelcamel, you can find this open box for less than $40.
At the other end, we use a Blue Snowball because the standup takes place in a large open room and we want the cardioid pickup pattern so we don't pick up extraneous noise. As with the other microphone, sound quality is a lot better when you are near the mic. I had someone who spoke softly, and I always had to get her to stand in front of the microphone, but a fellow with a booming voice was ok from 8 feet away.
Two hours for a one-way commute? That doesn't sound like a very good life balance. I think if that was our teams that we'd end up doing a mixed online/f2f meeting as if some of the team were remote.

That's why we have flex-hours and most people work from home most of the week. Right now, we don't even have enough desk space for everyone if they come to work at the same time.
In this area, it's not just work-life balance, but housing-work balance -- the farther you drive, the cheaper your house, which can make the difference between being able to afford living in the area or not. Even if you can afford the mortgage on a $750K starter house, not everyone can cover the downpayment, and when making offers they are competing against people paying cash.
Works like a charm in somewhat noisy environments too.

We already have one of these. The speaker is good. It's the mic that's rubbish. If you hold it too close the sound is mashed. If you don't then no-one can hear you because of the room...
Thanks for the suggestion anyway.
You need two things:
1. On your end, a flush mount PZM. Mount this in the center of your table.

2. They MUST use headphones (not speakers) on the other end, or you will get massive feedback.
I currently work for a small (50 employees) engineering company. One person in my present team's weekly standup is in Montreal, Canada. Three are in New York, USA. Three are in London, England. The rest are in Glasgow, Scotland. In my last job, with a major international bank, one standup member was in Chennai, India; three in Geneva, Switzerland. One in London, England. And the rest in Glasgow. In the real world 'everyone in one room' just isn't going to happen.
I'm old enough to remember when discussions on Slashdot were well informed.
This problem was solved in 1965. Just get a Cone of Silence (http://en.wikipedia.org/wiki/Cone_of_Silence). Just be sure you don't get it from a "discount place".

I use a Heil GM-5, it's great for everything from studio to auditorium to outside recording/broadcast (even looks good on a butt-ugly boom). For a stereo input via minidisc (if I'm not doing live in particular - and certainly if I'm shooting for stock footage, as I've yet to come across a camera with any kind of decent internal mike) I use a Yoga EM-268.

Works for me (on linux) - good pickup for a medium-sized room, good sound (though you can use it just as a mic).
