Memory Size The size of an mp3 depends on two things, quality and length of track. A good rule of thumb when deciding what size you’ll need is you’ll usually get about 1 min for every Megabyte (Mb), or approximately 200 songs for each 512Mb you have of memory at an average to good recording quality, at that size you’ll be able to store around of course you can get much more, or less by altering quality of track. Another term you’ll see around is a Gigabyte (Gb), a Gigabyte is a measure of Megabytes (Gb), where 1Gb = 1024Mb. And if you’re wondering why its 1024Mb and not 1000mb… ask your IT support!
I take my mp3 player everywhere with me and only usually hook it up to my computer to add new music about once a week and like to have as much on there as possible, so I opted for a Sony 20Gb hard disk model, but if you simply want some entertainment while at gym you might want to save yourself a few quid and go for a cheaper solid state unit.
Battery Life Another thing to look out for when buying an mp3 player is battery life, until fairly recently average battery life for one of these units was around 4-5 hours max, but new developments from companies like Sony and Microsoft mean you can now get a battery life of 30 or even 40 hours between charges.
Be aware, some very popular units only sport an average battery life of about 4 hours, this can be very annoying, make sure you check facts before you buy.
Portable Storage Many players these days allow not only storage of audio files but also any other computer files you might want, connected simply with a USB cable, so it’s can be a handy way to transfer your files between home and work.
So what’s next? As mp3 player technology becomes advances there are more and more features being added to these units, some later generations of IPod for example have built in digital photo albums; you can download your pictures and flick through them on move. Whereas other units have incorporated analogue radio and even DAB digital radios receivers. On a side note, mp3 player sound quality is only as good as headphones you listen with, I’d personally recommend spending a bit of time and money here, difference in sound quality and clarity you’ll get from a pair of Shure e3c earphones for example far outweighs cost of around £99.
