Cordless Headphones

15°C  -  12 mph W Wind Speed  -  23 mph Gusts  -  Overcast. Took my laptop into PC World so they could get me back on Desktop  -  they've kept it to do what necessary.  While I was these I bought a cordless set of headphones for my All-in-One computer  -  worked perfectly first time and then renneged (don't know if I've got the right word!!) on me.  Back to PC World tomorrow.  Don't feel much like blipping after such an unsuccessful day!!
