Impedance rate

MP3 players Sansa Clip | Clip+
1

Hello,

I’m willing to order the Sansa Clip but I can’t find any information on the impedance rate. Can somebody help me?

I need to know this because I want to make sure they match my earbuds (16 Ohms).

I don’t know which is the impedance yet, but I am trying to figure it out. I think the linked pages in the bottom comment says it is 21 Ohms, but I am not an expert. It has been a long time since I did anything with electronic circuits.

You will not find an output impedence for a portable device that corresponds to the rated impedence of the headphones. If you find the spec it is likely to show a high output impedence  for the device relative to the impedence value of the headphones. You need to know that the unit will deliver adequate power output to the phones you are interested in. Typically the phones will be anywhere from 16 ohm to 32 ohms. Maybe even up to 50 or 60 ohms. Those should be fine for most portable players output. My 600 ohm AKGs are too high impedence for my players to deliver adequate power. In other words, they don’t play loud enough. Usually if your phones are rated at under 100 ohms you will be OK with most portable players.
That’s my not-so-technical understanding anyway.

best not-so-technical explaination I’ve read thus far.
