V O M O – Voice Over MObile recording Studio

New features and Benefits compare to CoVB2.0

Voice Over Mobile recording studio ( VOMO)  with Sound Isolation Hood (SIH) is the next step in Portable audio recording studio development allowing the voice actor to completely eliminate room tone and reflections in their recordings.


VOMO  Based on the COVB2.0, so I will not describe the features of the booth itself in detail, but stop on the differences and benefits.

The demand for improving on the COVB2.0 came from professional customer’s feedback and chasing a better, more accurate sound.

There three main complaints:

1) the room tone was still being heard in the recording.  People were solving that problem by adding an extra blanket over their heads.

2) the loops for accessories were a bit annoying, people did not want to look at the accessories while recording, they were also getting in the way when opening or closing the booth

3) bottom strap was  not durable.  Arches would rip the grommet holes and fall out of the base strap.

4)  Support Rods were sliding out of the channels and piercing the cover

5)  booth mounted on a mic stand was wobbly.


People never returned a single booth, for the reasons of the above issues, because everybody acknowledged the high quality recording environment it provided.  It was more like wishful thinking.

Eventually Dean Wendt, ordered the first custom “hood” to be made.  He did not know that it was going to be a hood. He said that he saw a demo I had made “not for public” where I suggested a small blanket to be thrown over the head,  and he wanted the actual fitted attachment to be made.

So it is with his blessing I would say, that the VOMO was born.


We started offering custom made SIH prototype and soon noticed that most people were ordering  COVB with the SIH.

New elements:

  1. Sound Isolation Hood – SIH – A sound absorption hood made out of Producer’s choice blankets and designed to cover the sides and the back of the voice actor while using the COVB. SIH designed to attach to the COVB by means of special hooks and rings.   SIH in combination with COVB provides 360 enclosure all around and from the top.  There is no other portable device that allows such coverage using highly sound absorptive materials.  The ceiling is usually the least acoustically treated area in home VO studios, yet this is a huge reflective surface.  VOMO gets this under control.

SIH  made as a three sided “box” with no bottom. There are two rigid fiberglass support rods built into the “roof” of the SIH.  Note: when attaching the SIH to the COVB the rod channels should be on the lower ( inner) part of the Hood, not on the outside ( top) part. Outer end of the Rod channel equipped with D-rings to connect to the Snap hooks on the COVB.

The rod channels are not parallel. They are spreading outwards to provide better support of the hood.

When using the hood it should NOT be rested on your head. It should be completely supported by itself.

  1. SIH Attachments : There are several additions that had to be made to the COVB 2.0 to make it compatible with the hood.
    a) Case corner links with two D-rings, Inner and Outer. These links are there to create a connection of the booth to the Stabilizer strap. There is one link on each corner of the Blue outer case..
    b) Snap Hooks on the booth canopy. Bottom Hooks and Top Hooks.

Bottom hooks designed to connect to the Case Corner link’s Inner D-rings.

Top Hooks designed to connect to the SIH D-ring.
c) Stabilizer strap. Stabilizer strap is a 8 ft long adjustable strap with two Snap hooks on each end. Stabilizer strap designed to be hooked onto the Case Corner link’s OUTER D-rings and run under the Microphone stand. It can also be used with a weight, such as sand bag, dumbbell etc.  Stabilizer strap helps to counterweight the booth when the SIH attached to it. Even without the SIH the Stabilizer strap  makes the COVB mounted on a Mic stand less wobbly.

3. Accessories bag. In the COVB2.0 we were very proud creating a way of holding all the accessories on the booth’s back wall.  In reality it did not prove to be a good idea…. The Accessories were getting in  way of opening the booth, then if you put something in it – it would damage the pop filter. And when it looked like a “garage wall” with tools hanging all over. People did not really like it and some let us know about it.

So in the COVB3.0 we introduced an accessory bag, that is attached to the bottom of the support table by Velcro strips and it holds you basic accessories, such as script holder, Pop Filter, Miniboom and Micromic stand.  Only the Microphone mount was left inside the booth.

The accessory bag also has an additional functionality of balancing the COVB and making it a little more stable.

  1. Base strap.  The base strap design was a pain and I knew it.  But I could not come up with any other decent idea without making the whole design overly complicated and expensive.  Eventually I designed a special buckle that would support the arches and allow then to swing and at the same time would protect the booth, slide easier without damaging the booth and be more durable and easier to use with the strap.

A special mould was created and after few tries the final buckle emerged.   The arches are installed in the buckle and have screws as axels to allow them swing into open/close position.

Currently buckles com assembled with straps sewn on it. But the ends of the buckle where the strap is connected to includes a self-locking design so if for whatever reason the strap needs to be replaced it can be easily done even without sewing.

  1. Secure Support rods channels. The Support rod channels designed in a way that the Rod can never get out on its own.  There channel made out of a strap folded in a way that it forms a loop that holds the rod in place by itself.  To take the rod out of a channel you just need to pull it from the side opening.
  2. Bottom side stitched. The sides of the booth used to be joined by Velcro. Initially the thought was that it will be easier to take the booth apart or open the sides if necessary. But over time we realized that nobody actually taking it apart. Also if the booth washed  Velcro gets all smooshy and wrinkled and during the wash it rips into the blanket cover and makes total mess. So instead of Velcro we just stitched the sides together.  There is still an opening in the back of the booth for the cables and wires to get in.


Wobbliness.  Even though we had tried to address the “wobbliness “issue, it is hard to defeat gravity.

The booth itself weighs approximately 12 lbs.  With the SIH it weighs about 15 lbs.

Obviously if you balance 15 lbs on a ½ inch stick 5 ft in the air it will be a little wobbly.

This is where a shorter person can clearly claim an advantage!

If there is no need to raise the booth high , telescopic design of mic stand usually has enough strength to provide adequate support.at abut 4 ft height. Raise it another foot and the Mic stand gets “overextended”, which is never a good thing!

Stabilizer strap works well, but make sure that you tighten the mic stand well, otherwise the tension of the strap adds to the weight of the booth and can pull it down.

Second mic stand might provide additional security, if you just stick it under the booth as extra support.

      7.  LIGHT! I almost forgot about the LIGHT!


I consider new LED light is a huge improvement over the COVB2.0.

And not just because it is cute, but it  is much brighter, the light is nice white, it is rechargeable, it charges from USB cord and can work from your computer or wall outlet.  It can stand on its own and it can clip to anything inside the booth.  We found that the best way is to clip the light to the base strap on your left or on your right .  I suppose you can also clip it to the hood, so it hangs down, or we left the elastic loops at the top of the booth, “just in case”


And now : pictures that “speak louder than words”.

(And if I add words to the pictures would that make them sing? Or just shout?)

Accessories bag located at the bottom portion of the table. It may be hidden by the Blue outer case.  It might be a little challenging to take the contents out of the bag, but I thought that you only do the set up once and I did not see any other inconspicuous place to fit the bag.  Leaving it loose inside the booth, did not look like a good option.  Bag is removable.


It is attached to the table by two Velcro Strips and can be taken out if necessary.
The bag has 5 pockets of different sizes: Left to right:

1] Mini Mic stand,

2] Miniboom,

3] Script Holder,

4] Pop Filter ( 6 inch),

5] Goose Neck pocket.

To Open the VOMO place it on a table, unzip the top compartment. Reach inside and  Pull on the base strap. Stop at approximately the level of the Side Velcro holds  If you pull the base strap too much out, the top will be collapsing back. Ideally the arches should form an upside-down even sided triangle. The side Velcro holds designed to help keeping the arches spread apart. But it is optional.

Here is an example of the COVB feature that some people might not be aware of.

Sound Isolation Hood – folded onto the COVB

If for a voice actor the acoustic environment must be absolutely dead,  meaning no reflections and no room tone,  For singers some reflections may be beneficial. The side panels of the COVB may be opened up and the top pushed back to open the mic to some liveliness of the room.

I think this is another benefit of the COVB that no other product can offer. (I was going to say in this class. But isn’t the COVB is in a class of its own? J )

Side Velcro Holds designed to close over the arches to keep them open. When closing make sure to “push the Velcro in between the arches so it sticks not only on the sides, but also in between.


To feed cords into the booth there is about 5 inch opening in each corner of the booth.


The Base strap Buckle. Provides smooth operation and assures that the sides are not damaged.


The buckle supports the arches allowing them rotated in fold/unfold position.   Buckle also designed to be connected to a strap without stitching.

Mic Mounting Bracket. The only one left inside the booth.

The light  is very cute, flexible neck, nice bright ( but not too bright)  white light.

You need to touch that  little star to turn it on and it is a little slow to turn on/ off  (LED has its own problems). So if you do not drumming your finger on that star – it will turn on the first time.  Battery holds power for about 4 hrs.

It also has a little on/off switch on the back.. so it does not accidentally turn on in the bag and waste battery.

As I mentioned earlier you can clip it anywhere, but I thought the best way is to clip to the base strap:


Folds nice and flat

When unfolded the Support rods must be on the inside.

Stabilizer strap.

SIH attached to the COVB 3.0.   table top.

As you can see the SIH completely covers the speaker from all sides.

And the lamp produces plenty of light. That generates no noise and practically no heat.

When SIH is not needed you can simply fold it back onto the COVB.

It actually will triple the layer of blanket on the sides and the top, and you can still record that way too.  It actually might provide better  reductions of noise coming from that direction

The COVB 3.0 can be used on a mic stand just like the COVB 2.0.

If SIH placed on COVB 3.0 on mic stand  SIH tilts the booth too much the front. Using stabilizer strap allows to correct that and to straighten the booth position

Technical details:

Support Rod Channels.

Booth structure the canopy and the hood are held in shape by fiberglass support rods. In normal operations there is no need to take them out, but the booth covers must be washed, then the metal arches and support rods must be removed.
