I purchased the 6015i recently, and am a little confused as to what
headset to look for. Here's why:

- The Nokia accessory page shows all headsets with the proprietary data
port connector.

- The Shure website says I can use the 3-connector QTS-3 with Just
Wireless part# 07142, or Belkin part# F8V9020-CNCT as adapters, both of
which plug into the data port at the base

- I plugged in my Etymotic headset into the only 2.5mm headset jack I
could find on the phone (on the side), it's a 3-connector standard, and
it works fine.

- Shure says the QTS-4, with the 4-connector plug, is designed to work
with the Nokia phones.

So, I know the 3-connector regular jack works fine, I would really like
to know if I get something extra with the 4-connector 2.5mm jack, or if
it's not compatible at all. Or, on the other hand, if I gain anything
if I use the data port connector instead.

Thanks in advance! If I find anything on my own, I'll post it on this
thread, to make it easy for others in the future.
