difference between the voice quality of "1x" phone to the voice quality of older CDMA phon

Is there really a (substantial) difference between the voice quality of "1x"
phone to the voice quality of older CDMA phone.



Is it better or worse? Also if worse is there a tweak to force it into a
different voice codec?

I can't say the official sound difference, but with what I have noticed,
"CDMA 2000" sounded good, but "CDMA 2000 1x" makes it sound like the
other caller is at the end of a long empty hallway (minus the echo), and
it got much harder to differentiate voices (for example, I have three
friends who use a single CDMA 2000 1x phone, and I CANNOT tell the
difference between their voices on the handset, at all). I find these
differences in hansets from Auidovox, Nokia, Kyocera, and LG phones. I
don't know anybody with Samsung or Motorola 1x phones.

CDMA 2000 and CDMA 2000 1X are the same. Personally, I really can't tell
the difference for the systems, I think the handset is more likely
responsible for sound quality. Samsung phones tend to sound much better
than other phones, while Kyocera with the Smart Sound turned on is probably
the best option if you are often in really loud areas.

I haven't heard any difference, either, but am finding the extra system
capacity a boon in a couple of areas that are normally swamped during rush
hour.

You must be smoking crack. The EVRC coder used in CDMA 2000 sounds
like horse****. It's very dead tonally compared to GSM's EFR or the old
13k Qualcomm CDMA coder. The only problem with the Qualcomm 13k coder is
it doesn't render the "s" sound well.

By the way, I had an opportunity to sample the new AMR coder used by
Cingular in their GSM 850 rollout. It is actually quite good. In fact, I
could not tell the different between it and my T-Mobile phone. The
Samsung handset I was testing actually sounded a little bit better than
the Nokia 8390 I use on T-Mobile.

My subjective opinion is that my Kyocera 7135 with 1X sounds better
than my previous phone, a Motorola T720. There was no indication on
the phone or manual that the T720 used 1X. Of course, the T720 is a
piece of crap, so it could have just been the phone and not the lack of
1X...

The T720, if it was a CDMA version, is 1x, but, obviously, only if 1x
service is available.

I'm using a V60i, a StarTac 7868 and a T720 on Alltel and a T720 on VZW
at the moment and I can't see any problems with 1x. This is in an area where
we have both Alltel and VZW 1x. My wife, who has better ears than I do,
thinks the 720 sounds as good as the StarTac. She refused to use a Kyocera
2035, as did I. We both felt it has poor audio.

Knocking on wood, the 720's have been ok for us. I already had cables
and chargers, so I took a chance.

Would love to try the 7135. If I still used Palm OS, I am pretty sure I
would want one.

Again, subjective here...but my LG VX4400 sounds better to me than my
old Nokia 5185i. I know for sure that Nokia didn't have 1X.

Like you, I don't know if the improved audio quality is the result of
the phone or the network.

I have yet to discover anyway to tell if 1x is even being used for
voice. I know it can be, but my Verizon sources have told me it's only
being used for data here in SF California. Some of the phones come out
of the box detecting the 1x network and displaying 1x and some don't,
but that sure doesn't mean it's used. Kind of like the unsupported GPS
feature. It's displayed but not supported with the E911 base equipment
yet, at least around here.

So unless someone has a Verizon 1X voice map, a news article about 1x
voice deployment on Verizon or a debug menu to check during a voice
call, I'm not yet convinced it's being used widely, except for fast
data connections and to light up that 1x icon on the some handset
displays.
