Things that totally surprise you
Today I got a delivery of a pair of headphones that I hadn't ordered, the Sennheiser HD 100s. I filled out a survey some months ago and forgot all about it - the headphones must have been one of the possible prizes for doing the survey.
As it turns out, they will come in very handy as I didn't have any wired head or earphones with a 3.5mm jack, breaking my last pair just over a month ago. I now have 3 pairs of headphones and one pair of in ear Bluetooth earphones. I had gone totally wireless but these will come in handy with my iPod Shuffle which I couldn't use without wired headphones and I lost the dongle that came with my iPhone.
I'm a bit of an audio nut, and while these don't sound as good as my expensive headphones, they are pretty good. And free too.
The shuffle is 8 years old but still holds a good charge; I've got 250 of my favourite songs on there. It takes a 3.5mm cable to USB for charging and of the 14 hours stated battery time, I'm still getting 12.5 hours. I did a test a couple of months ago.
