Good buying experience for HiFi headphones

I have been looking at buying a set of wireless headphones and have always been a Sennheiser fan. i checked on line with a few shopping companies to get an indication on price. Note no expertise offered. I contacted Hfx systems on Tuesday morning to be told I was looking at the wrong sets due to the age of my amplifier. They told me what i needed to buy and the price. much to my surprise was ZAR 700 cheaper than the popular online shopping site. Rushed off and bought them just like a kid in a candy store. Set everything up as instructed and waited for them to charge. This morning much to my horror they wouldn't work, No problem phoned Hfx again, within an hour a guy came out and sorted everything out. Wow what a good buy. Thank you very much HFX Systems
