This is admittedly a deep dive into a niche topic. It stems from work done for ZipDX, but is more technical than most audiences can stand. Nonetheless, those of you who frequent these waters may find it interesting.
Why Do This?
One of the more fascinating aspects of my work at ZipDX involves the interpreters engaged in the use of our multilingual conference capability. These people, who are located all over the globe, are simply fascinating people. They have incredible skills with languages, and finely tuned sensitivity to the nuance of cross-cultural communication. It’s positively inspirational to hear them at work, and very gratifying to support them in their work.
I love when things “just work.” This happens so rarely as to be noteworthy. What follows is a nice example with respect to my PolycomVVX-600 and a USB-attached headset.
This afternoon a plaintive beep in my ear told me that the battery on my Sennheiser DW Pro2 cordless DECT headset was nearly depleted. This when I still had a lot of my working day left. Looking across the room I saw a wired headset that I have been evaluating for some ZipDX applications. It was a Passport 21P Headset, fitted with a Plantronics DA40 USB Digital Adapter.
A couple of weeks ago, over at the Broadband Reports forum on VoIP Tech, there was a question posed about selecting the best low cost microphone for VoIP applications. This is a topic that I’ve considered at length. It has much in common with my background in recording and broadcasting. On that basis I weighed in with some opinion. As I my way, I probably provided a longer answer than anyone anticipated, or even wanted. After re-reading it a few times I thought it worth sharing here as well.
The original question:
I realize many problems people experience are due to a lousy mic that isn’t noise canceling or picks up sounds from a anywhere in the room. There are many ways to improve this. I like the idea of a pickup pattern that is very isolated in front of the mic and within a finite range so I don’t have to wear the mic but maybe this is asking too much. If the mic only picks up sounds very close to it, wearing it can sure avoid a lot of problems. Don’t know if firewire or USB3 is better than USB2 or if its better to run the mic directly into your mic input of your motherboard or audio card or something else. Latency is not our friend! VOIP is so sensitive to extraneous noise so this needs to be addressed and is dependent on the ambient noise of the user. Any recommendations? Few of us work in a soundproof office.
Prior to smart phones life was much simpler…at least with respect to the wiring for headsets used with portable music players vs cell phones. A recent project has me dealing with some wired headsets. I thought it worth sharing some of the things that I’ve noted along the way, along with just a bit of the history.
What I’m describing relates to the various ways in which the common headset connector has been used over time and across a number of application contexts, including:
In the beginning there was the pocket transistor radio. When Sony got around to it some transistor radios featured a 3.5mm (1/8”) 2-conductor jack. This was intended to receive an earphone for private listening. It was also called a “mini-jack” since stereo headphones for listening to music used the full-sized, 1/4” phone plug.
It’s unclear if the creation of the earphone feature was motivated by the desire to listen to the radio after bedtime, or avoid aggravating the Mrs with the play-by-play of the baseball game.
Recently someone found this site while hunting around for insight about the ideal headset for their small office. Not finding exactly the answer they were looking for they emailed me the following note.
I came across your blog and I love it. I run a digital agency from my home office in Manhattan, and I’m looking for a high quality over-the-head boom mic bluetooth headset to use on my late-model Android phone for client calls. Despite all my research, I can’t seem to find a really good high quality boom mic bluetooth headset. I purely want to use this in my home office, as do several of my freelancers who also work from home. Any suggestions? Cost isn’t the issue, quality is what I care about most.
Well, Zachary, thanks for the kind words. I can see that we share a common belief that it’s worth the effort to communicate well. I share your frustration with respect to the kind of tool that you’ve been seeking. The solution isn’t obvious, but I can offer you some guidance nonetheless.
