What is the difference between the photive 4.0 bluetooth &amp; 3.0 bluetooth?

Bluetooth 4.0 is more energy efficient and has a faster throughput (more data at once). But these headphones already last long enough as it is (~10 hours) and the audio quality is great for the price. As far as these headphones go, Bluetooth 4.0 is largely unnecessary. Plus, the reason it's so cheap is probably because it only has 3.0, which is a worthy compromise, in my opinion.

I don't know for sure but I thought all Bluetooth signals are backwards compatible with old versions.

I ordered the Bluetooth version (2 times) but the seller (iPazzPort) sent me the non-BT Dongle version both time, so am not sure of the BT sync functionality. On the whole since it is working correctly with my laptop, I kept the device. I tried contacting iPazzPort but they are not reachable.

Yes... the iPhone will support the Bluetooth v3.0. It does not matter who your wireless service is provided by.

It seems to me, the 3.5 cord is a back up in case your battery dies. The touch features stop working when the battery dies too. The blutooth function does work while charging. I haven't been able to connect to more than one device at a time.

In addition to BT 4.0, this one is supposedly has more base. The silver one has a different button layout, allowing you to sharpen treble, etc. BT 4.0 does not drain the battery as much.

We apologize for the misunderstanding. The blue tooth model is currently only compatible with IOS but we are also working on Android APP. We also have a WIFI model for this one which is compatible with both android and IOS but not ready to go yet.

I do not have 4.0 but on mine if you hold on the device in the Bluetooth menu it should prompt you to choose automatic connect or to ask for password

Yes, it's bt 3.0. and it really does have a long lasting battery. I'm very glad I bought it.

The specs of the laptop I have been researching (Toshiba Satellite C55-A5190 15.6") does say it's Bluetooth 4.0. Hope this helps.

since this is a receiver I do not think it matters. The transmitter is the one that needs 4.0. However due to size and features I would think it would be 2.0 at its best. I have used it and did not hear any difference between this unit and my 4.0 headset with Bluetooth coming from pc audio.

With iOS7, BT 4.0 LE (Low-energy) was added. Only devices that support BT LE can use this protocol (such as the Pebble Watch). The A73 still uses 2.1 BT technology. 3.0 BT has a better audio quality.

Apart from the Mike difference as told by many reviewers, the 10-10 seems to be using the Bluetooth 2.1 version and the 10-11 seems to be using the Bluetooth 3.0 verison

Depends on which version of bluetooth it is. 3.0 version is all I could get to work! Selecting individual albums no, artists to a point just make a playlist genre same just make a play list other wise no!! If the Zen can recognize car stereo blue tooth you got smooth sailing. Otherwise your blue tooth is screwed!!! Works well if it can recognize your blue tooth item be it stereo, car stereo or head set. Most of my 3.0 headsets were unrecognizable. Very hit or miss but sound is great but range is also limited! Look some where else, there are better ones out there, but they do cost quite a bit more. Good luck!!!! Controls to put the zen into pairing mode suck! Depends on which version of bluetooth it is. 3.0 version is all I could get to work!

If the unit has a thunderbolt connection it supports usb 3.0 through that connection. The 3- 2.0 usb slots are not upgradeable without physically changing the ports that connect to the mother board, in short no). (http://www.apple.com/thunderbolt/) The blue tooth version is generally related to the software support of the operating system and sometimes can be modified by pluging in a usb adapter that supports the blue tooth you are desiring. Therefore depends on the operating system and possibly a usb adapter, as to the bluetooth version your system will support. Hope this helps.
