Wireless microphone solution for PC/mobile phone

Postby aldib » Mon Apr 12, 2021 12:17 pm

Hi,

I would like some advice about a wireless microphone solution that I could use both business meetings, and simple content creation.

Before I go ahead with the details, I would like to disclose that I have little to no knowledge of electronics or sound engineering. Thus, I would like to apologise in advance for any idiotic statements or questions that might follow.

I am looking for a wireless microphone solution to solve three problems:

1. Business meetings from home (50% of the time). I spend in excess of four hours in business calls every day, and it is important that my voice is clear to the other participants. Unfortunately, I can't tolerate any type of headphones around my hears for more that 30/40 minutes at the time so end up using the loud speakers of the monitor and continuously mute/unmute the the microphone. I recently borrowed a Jabra loud speaker which is great, but I can't really use it to solve the other two problems.
2. Business meetings on the go or in an open-office space (30% of the time). I often need to take calls (before COVID at least) on the go on (airports, train stations, car) or in an open-office space. I normally use an old pair of Apple headphones that came with the phone. They get the job done, but I often get complains that voice is not very clear, and that there is a lot of background noise.
3. Creation of short training videos, either recorded or as live streams (20% of the time). This is nothing too advanced, just me explaining something in front of a whiteboard. I normally use the Apple headphones + Logitech Brio, but it's a pain to deal with the cable extension and the quality is not great.


Problems that I DO NOT need to solve are:

1. Long distance between wireless RX/TX.
2. Hiding the microphone under clothing. The size (as long as it is portable) is also not a major concern.
3. Very high level sound quality (e.g. needed for music or songs). My goal is for my normal voice to be clear to my audience.

Based on all of the above, I have been doing some research on combining a wireless RX/TX + a uni-directional lavalier microphone.

For the wireless RX/TX, I shortlisted:

1. Rhode Wireless GO. I think the older model would suffice as I only need one TX, but the Wireless GO II is the only one that mentions "3.5mm TRS analog output, USB-C and iOS digital output – universal compatibility with cameras, mobile devices and computers". Does anyone know if the older model also supports connectivity with mobile devices and computers?
2. Saramonic Blink500 B5. Saramonic tech support confirmed the the USB-C receiver would work with a Windows 10 computer. I am not too sure if the PRO version is needed. It doesn't seem to offer anything major other than the price tag.

Choosing the lavalier microphone is where I get completely lost! It seems more of a form of art rather than a technical decision. From what I gather, I need to keep three factors in consideration:

1. The pattern. I would guess that cardioid/supercardioid/hypercardioids is what I am looking for because the on the go and open-office space constraint. Is this true?
2. Connector. The connector must be compatible the the TX, but I'm not sure if if it's possible to use adapters. E.g. could I use an adapter to convert from TA4F or XLR to a 3.5mm TRS?
3. Voltage. Lavalier microphones seem to require power (usually 1.5VDC to 7.5VDC) from the TX transmitter. Neither the Rhode Wireless GO or the Saramonic Blink500 seem to specify exactly what they provide. Is there some kind of standard/assumption on this?

Regarding the model, the cheapest uni-directional lav mic I can find with decent reviews are:

1. Shure WL184 (https://www.shure.com/en-US/products/microphones/wl184) with a TQG (T4AF, 4-Pin Mini) plug.
2. Sennheiser ME 4 (https://en-ie.sennheiser.com/mini-laval ... peech-me-4) with an operating voltage of 7,5 V and 3.5mm (TRS?) plug.

Not sure if any of the two are even compatible with the Rhode or Saramonic TX.

Any input/suggestions/clarifications on any of the above would be very welcome.

Thank you in advance.

Welcome!

Wireless isn't the answer to your problems... especially in noisy environments.

Does your 'avoid headphones' scenario include a single on-ear headphone? I have one of these:

https://www.ebay.co.uk/itm/Corded-Cell-Phone-Headset-Monaural-with-Noise-Cancelling-Mic-Xintronics-3-5mm/292938552823

which works well and excludes most background noise.

Or you could try something like this:

https://www.gear4music.com/PA-DJ-and-Lighting/SubZero-Single-Ear-Headset-Mic-Compatible-w--Sennheiser-Systems-Tan/1UU1

or this:

https://www.gear4music.com/PA-DJ-and-Lighting/SubZero-Headset-Mic-Compatible-with-Sennheiser-Wireless-Systems-Tan/1OGR

with appropriate connectors/adapters for your kit.

Of course you can also get clip-on mics that connect directly to relevant kit. For example:

https://www.gear4music.com/PA-DJ-and-Lighting/Rode-Lavalier-GO/32YI?origin=product-ads&gclid=Cj0KCQjw38-DBhDpARIsADJ3kjmtGi3AP0jEaQc2HL7tOoSXg6hxQ1pjxg_VRItwv9oApRb20VLccioaAnsKEALw_wcB

I'm not quite sure why you're muting/unmuting your mic in your present arrangements... Apps such as Zoom and FaceTime cope well with 'live' mics.

The key thing is to get the mic close to your mouth - especially in noisy environments or where the acoustics are 'echoey'. Wireless won't solve that problem... but neither will a conventional clip-on/tie-clip mic

I have tried anything from large circumaural to small in-ear headphones and for me it's a guaranteed headache after 40 minutes. Said that, I recently purchased a pair of bone conduction headphones (Aftershokz Aeropex) and I can tolerate them for much longer (2/3 h). Audio quality is not the same, but I doesn't need to be for what I use them for.

The reason I'm looking for wireless is that the whiteboard is a couple of meters away from my machine and dealing with long extension cables is a pain.

Potentially, I could pair the Aeropex with the lav mic to eliminate the need of loop cancellation (MS teams on Windows 10 does cope well with 'live' mics in my experience) . Assuming this to be the case, could anyone recommend a good wireless RX/TX + lav mic combination?

Ah! OK on the need for wireless...

The Wireless GO from Rode has had good reviews from people I respect...

So one of those coupled with a Rode Lavalier GO and/or a Rode HS2 (choose your colour to taste) should see you right...
