I considered buying this in the past in order to avoid wearing a headset on my head, which makes the coolest person look geeky but with this, you can put the speaker whereever you want and you can communicate on xbox live freely.
Now this is available at just £5.00 delivered and go through Quidco to receive 4% cashback making this just £4.80 all inclusive, which has an RRP of £14.99 and was previously £11.99 just moments before.
1) Two-way Xbox 360 Live communication device removes the need for headset during online play.
2) Powerful integrated Speaker, Microphone and Volume Control
Compatible with Xbox 360 wireless and wired controllers
3) No batteries required
Hope this helps. :)
