That natty little player was covered
here a while back. To date it has proved to be a very good purchase.
Buttons and switches: Took me a while to figure it out but second nature now.
Screen: Totally naff but I don't generally use a screen so of no consequence.
Battery life: I'm using rechargeables so don't have any issues.
Interface: Simply plug and play. Faultless
Build quality: Initial impressions were that it seems a bit flimsy but it has been fine. It's no iPod but then it cost almost a tenth of the price of one with equivalent capacity.
Radio? I haven't tried it. I'll give it a whirl today.
Earphones. Haven't used them. I use a pair of Sennhheiser's. They look very poor though and have moulded ear pieces rather than buds. Such designs I find very uncomfortable to wear.
