So the SL6000 2.5m has has either,

- a stereo audio out
- a mono audio out and microphone in

but I cant imagine both. I haven't tested my unti yet, but can folks vouch for one or the other?

Thanks,

No, it has both. The switch is automagically done when plugging the device. The Zaurus recognize from the impedance if there is a mic (input) device or if both channels are for output.

And for the details (I haven't test this myself) just consult the following thread:

Yup, absolutely right. I saw the impedance post, and just verified it.

Anyone know of really cool mikes to use? I'm using Chameleon cellphone headsets, which are okay but not 'secret service' cool factor.

Thanks,

Why Sharp decided to put a 2.5mm jack in the side of the z6k will likely be one for the ages.
I would suppose it was figured that the Z would be used more for VOIP with existing 2.5mm cellphone headsets than an mp3 player with "standard" headphones.

But if you want to listen to mp3s thru your headphones, you have to put a 2" adapter plug sticking out at a right angle from the Z which will only cause unnecessary wear and tear.

I found these (seemingly) nice 2.5->3.5mm adapters which include a short length of wire between the jack and the plug and with a right-angle jack on the 2.5mm side.

or

this one should be fine even tho it says for the treo


*disclaimer: I haven't picked up one/any of these yet, so I can only assume they would work and not cause any impedence issue with auto-sensing of the I/O for the headphone/mic jack.

enjoy....

Since I have already lost two adapters I am looking at getting headphones that already have the 2.5mm adapter. These are some of the ones I am looking at:

JAVOeBuds - 2.5mm Retractable Stereo Earphones (black)
Seidio Treo 2-in-1 Over-the-Ear Headset
Seidio Treo 2-in-1 Backphone

I have not got any of these yet but plan to get something around christmas time. If anyone has tried any of these or something like it let me know.

After trying a 2.5mm male --> 3.5mm female adapter from Radio Shack ($3.99) I decided to return it and make a cable adapter myself. The adapter is way too bulky and too long. It feels like it could disembowel the SL-6000L if you accidentally push or pull it sideways....

I will "sacrifice" a cheap cell phone earpiece I got at Wal-mart ($1.00!!!!) to re-use the 2.5mm plug and few inches of the wire attached to it.

I exchanged the Radio Shack adapter for an in-line 3.5mm phone jack (RS catalog number is 274-274, $3.99 for a pair), so I just need to make three solder joints and I'm in business.

Once I do it I'll try to post a picture here. It will look very similar to the Hama cable adapter.
The cell phone earpiece plug is angled and the smallest I have ever seen. It will put almost zero strain on the SL-6000L socket. The in-line phone jack is a little on the bulky side (don't understand why they made the case so big....), but at least is at one end of the wire.

Total cost: $3. biggrin.gif

I got the one from Seidio and it's perfect.. although, it costs a little more, especially once you factor in shipping charges... I got 2 since it made no sense to pay a shipping charge what was 100% of the item price... this way, at least, it's only 50%... small consolation.

seems as tho the link went bad/changed...
here it is again
http://www.seidioonline.com/ProductDetails...de=ADA%2D25M35F

here's a pic with it next to a ruler (I took the pic with the zaurus cam, it wasn't possible to show it with the Z now was it?)

the only "problem" is that it could be easy to lose, but that would be true for any adapter (also why I bought 2)

again,,, _WHY_ did Sharp chose the 2.5mm jack.?.. :-P

Nice, I'll try to make mine look like that laugh.gif

I guess the main reason for Sharp to go with a 2.5mm socket is the corporate market they were targetting. It makes the Z directly compatible with cell phone earpieces.

Heck, the Tungsten C not only has the same socket but, unlike the Z, does NOT have the autoswitch function to go from micro/speaker in mono to headphone in stereo. You are stuck with mono sound AND an adapter.......

Let's be thankful for Sharp foresight biggrin.gif

Anyone found a good set of headphones for the 6K that have the 2.5mm plug? I would prefer not to have to use an adapter if I don't have to. All the ones at my local Best Buy have the 3.5mm plug.

Greets All,

I was Christmas shopping in Office Depot this evening and I found an additional solution to the ones listed above. This particular solution is a pair of stereo headphones from HP. I went over and paid my 2.5 cents per copy to make photocopies of the bubble pack front and back because I couldn't immediately discern what the part number was.

Basically they are simply a pair of normal stereo earphones, (earbuds), with a 90 degree 1/8" (3.5mm)female to 3/32" (2.5mm) male adapter included right in the bubble pack. I had the manager scan the price for me and he said it sold for $9.99. I didn't actually buy it because I had already ordered the adapters from Siedo mentioned earlier in this thread. I obviously can't vouch for their sound quality but other than including the adapter they look fairly run-of-the-mill. For $9.99 it seems a good value regardless of the quality if low end earbuds don't bother you too much.

Here's every word of what appears on the package:

It is probably reasonable to assume since they are manufactured by Belkin that Belkin would have the same product available under their name plate also. Hopefully this has given you some place to start Googling from at any rate.

Seidio changed the product code and hence the link is now outdated.

If you'd prefer an adapter and not earphones, go to:

http://www.beststuff.co.uk/headphone_accessories.htm

... then scroll down to "Best stereo headphone adapter lead 2.5mm plug to 3.5mm socket"

... and this is what you'll read:

Hama Stereo Headphone Adapter 2.5mm to 3.5mm

Some devices have 2.5mm jacks (PDAs, some phones etc.). This adapter allows you to plug a set of headphones with a more common 3.5mm jack into a 2.5mm socket. High quality headphone adapter. The advantage of the short leads is that you can plug and unplug headphones without putting strain on the source socket. Stereo adapter.

£4.49 - This is the price you pay no VAT or delivery charges to add within the UK.

I bought this and it should be arriving when my wife's parents visit from the UK on Jan 26. I had looked at the Radio Shack adapter when I was in the US for Christmas, but it stuck out way too far and I had read of some problems with it (i.e., having to leave it slightly "out" to get the stereo signal). This one is at a right angle and has a small lead.

<EDIT>Nevermind... that Seidio adapter is almost the exact same thing. But if you're abroad the Best Stuff.co.uk adapter might be a better option.</EDIT>
