That's a transmitter to two bluetooth headphones to a traditional audio source.

This product is a set of receivers for traditional headphones from a bluetooth audio source.

While they're related (one source to two headphones), they're solving different problems.

If you used the monoprice product with two of https://www.amazon.com/Avantree-Bluetooth-Headphone-Receiver... you'd have a similar setup.

If your phone allows pairing two bluetooth audio devices, then the Avantree product on each headphones is all you need. I don't know if any phones support that.

Or the Avantree product with a traditional headphone splitter.

They're basically different solutions to the same problem of letting two people listen to the same source via Bluetooth. The nice thing about doing it on the source side is that you can use whatever Bluetooth headphones you like, including ones where the Bluetooth receiver is built into the headphones themselves.

> Ok, so this is all just a concept. But we can turn this idea into a real product in a matter of 2 months.

Isn't this an absurdly optimistic timeline for a hardware startup? I notice that both of the project founders are marketers -- were any engineers consulted when coming up with this estimate?

@teraflop

Thanks for the comment. I want to clarify. By real product, I don't think mass production. I meant a working prototype with an acceptable design. Velo is an independent venture of mine, but with the full support of Netizens (it's where I work), once I validate the idea. I had consulted it with our R&D department many times along the way in recent weeks before I decided to go public with this concept.

@sahaskatta

This is one of the available solutions. However, you need to have a jack port. I read Apple is dropping one tomorrow.

Also in this case you need to have two Bluetooth headsets. Velo could support Bluetooth headsets, but traditional headphones seemed an easier choice.

BTW Monoprice works with up to 2 headsets. We think that we could connect more than two headsets with Velo.

Using traditional headsets is a great idea.

You should also IMO look into a software-only solution, i.e. a music player that streams its output to other smartphones via bluetooth or wifi. Because if your idea takes off, this is IMO what will kill a hardware product.

And you might eventually talk to accessory makers to build such capability into cases.
