  when I say usb dongle I mean for my pc

 
Just get whatever dongle you can get as long as it says "Apt X capable."
 

 
unfortunately the speakers are too tall

  unfortunately yes

 
Oh you didn't clearly answer him when he first asked what space you had to work with (just that you had space under the monitor), so I was working off the assumption that you might still have space otherwise. 
 
You can just get a soundbar, just know that it won't have the same sense of imaging as when you have two separate speakers placed farther apart.
 
If you can position a sub elsewhere though Creative has this:

Otherwise it's kind of difficult looking for a soundbar that will work. Many of the better ones seem to be taller owing to the larger drivers and take SPDIF digital inputs.

Haven't heard it nor similar products from the same brand but between that and a soundbar I'd gamble on that one.

 

[PAULRYAN52]

it's meant to sound good according to reviews, I'd prefer speakers over a soundbar, is it ok to place speakers behind the monitor if slightly to tall to underneath

 

[PAULRYAN52]

how about http://www.richersounds.com/product/standmount-speakers/tibo/plus-2/tibo-plus-2, i can fit 21cm if I place them in front of the monitor

How wide is the space? 18cm tall is pretty good--just a hair over 7". If the space is wide enough, you could simply turn some speakers on their sides.

 

[PAULRYAN52]

this is where the speakers are going

That requires a very small footprint due to the legs of the monitor. I'll look around a bit. This isn't an ideal space for studio monitors.

Well you don't go to a concert with a solid wall between the audience and the speakers, although that can tame the high frequencies. That could have the low freqs bouncing around back there between the monitor and the wall though, and you get bloated or at least imprecise bass.

Link isn't loading. Haven't tried it but again I'd much rather gamble on two separate speakers than a soundbar.

 

[PAULRYAN52]

at the moment it either the ruark audio mr1 or tibo plus 2 both should just fit

 

[PAULRYAN52]

ok say I may forget the wireless requirements and just get a long enough cable, what about a usb dac with good speakers is that doable for £250

 

[PAULRYAN52]

how about these

Tiny midwoofers forced to do more bass than they can through port tuning. Your thump-thump-thump easily turns into thwuuuuummmmwuuuuuubbbbwwuwuuuubbb on these. On top of that, they cost a fair bit more.
 
I'd be more inclined to use headphones than those.

ok so not them, but what 1s
