hands-free headset

my local walmart had a bunch of these on clearance for $1-the newer
phones are using a different portal style now. These on sale have the
half inch wide connectors with the metal prongs. I bought 2 to try-one
has 6 prongs and 3 prongs symetric spacing; one has 2 prongs and 2
prongs narrowly and widely spaced. How do I tell which one fits the port
at the botton of a cell phone? Will I see a corresponding set of holes
or prongs on the cell phone? The model number was not in the list of
model numbers on the packaging but I doubted they list them all anyway.
thanks

if its one dollar

then its probably not worth it

if you want to mess around then go for it!

if u want to invest in a better one you'll use in your lifestyle

then id suggest a wired jabra or a bluetooth headset depending if your handset has bluetooth capability

as for your compatibily issue

look at the connecting prongs

they should correspond with the headset jack on your phone

whether its a 2.5mm jack or a mini-usb port

it should say on the packaging! i doubt sumone will sell a product that has a totally blank box!

if it is... post a pic! thatd be qutie bizarre
