As you know, the Nexus One comes with a 4-segment 3.5mm headphone jack, whereas the standard 3.5mm plug has 3 segments.

I visually compared a standard 3-segment 3.5mm plug with the 4-segment 3.5mm plug that comes with the original Nexus One headset and they seem identical in length.

My only concern is that plugging in a standard 3-segment into this 4-segment jack will damage the Nexus One.

Better safe than sorry... so instead of empirically plugging in the standard 3-segment plug in the the N1 just to see whether it causes a fatal short or not, I prefer to ask those who are already knowledgeable with this: Is it safe to use a standard 3-segment with the N1 headphone jack?

Your phone should be fine.

Android wont route phone calls through headphones though, iPhone can be set to do so and uses the phones microphone.

An option I use to attach standard headphone to my Galaxy S is a simple BlueTooth headphone adapter(£10 from Amazon), that way I get to use MY headphones and make calls via them, plus you can keep you phone in your pocket when skating into town!

@Adrian Thanks. What do you mean by "won't route phone calls through headphones"? When I use the original headset that came with the Nexus One, I can hear the audio in the earpieces. Can you explain? Also, if you can provide a link (or just a brand/model#) to the Bluetooth headphone adapter you mentioned, this would be much appreciated. – Android Eve Apr 6 '11 at 12:00
Headphones don't have a mic, so Android cant use it as a Headset, even though the phone has a mic on it...I have this one from Amazon UK… I use it all the time, especially as I use Music Link headphones that work with my hearing aids - but it works with ANY 3.5mm stereo jack headphones – Adrian Apr 6 '11 at 12:09
@Adrian Thanks + 7. – Android Eve Apr 6 '11 at 12:19
@Adrian: what exactly do you mean by "can't use it as a headset"? I have a 4-segment audio plug that comes with my Samsung Spica, and I can use its mic just fine. – Lie Ryan Apr 6 '11 at 15:56
headSETs have 4 segment plugs, ground,left,right and mic - they WORK. headPHONES dont have a mic and only have 3 segment jacks ground, left, right, and cannot be used for PHONE CALLS, at least on my Galaxy S - so I have to use the BT adapter to use my headPHONES for music and CALLs – Adrian Apr 6 '11 at 16:16
