anyone with a jawbone?

Sennheiser MM100 bluetooth stereo headphones + microphone:

after seemingly successful pairing to the Jolla, the Sennheiser has crashed.
No more blue light on the headphone, also not when connected to it's USB charger. May need battery removal (tedious)
Note that Jolla media player when directly launched after pairing to the MM100 played at max volume and the Jolla's volume rocker did not control the volume any more.

BAD

Nokia Play 360° Bluetooth NFC speaker:

NFC does not wake the speaker most of the time.
One time Jolla NFC woke the speaker
But it does not initiate the BT connection automatically
This after previous manual BT pairing (speaker known to Jolla)
Speaker works normally when connected manually by Bluetooth.
Volume control by speaker or by phone.


For the always-on-battery-leeching-NFC I did hope to get better use out of the NFC.

So so

None of my wired Nokia headphones (HS-100, WH-102, WH-100 and WH-104) with microphone work properly -- when plugged some cracking sound can be heard all the time, microphone doesn't work at all and voice that can be heard is just strange, a kind a psychedelic

Have some wired Sennheiser for music and they work & sound great, Plantronics M55 BT headsed also work without issues.

And I am pleased to report that some low-budget USB solar charger also charge Jolla -- it doesn't work with Nokia E7, N900 and N9 (but work with older models like E71 that doesn't charge via USB).

@sponka it appears Jolla have gone for the more widely used US standard for headphones than the OMTP standard Nokia used to use. Nokia themselves also ditched OMTP in the latest Lumias.

The USB charging standard states that the two middle pins in the connectiin have to have a resistor connected or just shorted. This is what Nokia followed in the N9, N900 etc. Apple on the other hand decided to put a voltage across the two middle pins to tell it's products if the charger is compatible. Most 3rd party chargers follow the Apple rules. You can buy adapters that fit inline converting to the USB standard on ebay.

It's kind of sad that the standards were rolled over by the Apple accessory market but on a practical basis great that Jolla have realised which way the wind has blown.

Motorola SF600 works fine for talking, playback!
Jolla sets volume to 50% by default when you press play and asks for confirmation. also, the volume is set separately on device and headset, i.e. when you set the device to max., that isn't the highest possible volume unless you also set the headset to max.
When I had Jolla on 50%, some of the classical music was barely audible, I actually needed 100% on Jolla to get decent volume.
EDIT: when swithcing bt on first on the Jolla, then on the headset, it does make the connection automatically, but the sound is weird, metallic and distant. To get proper sound, it's necessary to switch the headset on first, then turn on bt on the Jolla and initiate the connection. that is the other way round from what I'm used to, and I find it pretty cumbersome, bcs you actually have to go into the bt submenu of Settings app - they gotta find a better way to do this.

That is pretty much incorrect, Nokia used a decent universal compatible reasonable non-proprietary AV-plug definition until they started their messed-up winphone stuff:

It's particularly Apple who use a proprietary non-standard non-compatible interface for their headsets. And to a marginally lesser degree 50% of Android devices.

It basicaly boils down to Apple using a weird pinout where GROUND is on the 3rd pin from top, and the very sensible microphone input is on the base 4th pin from top where you would expect sleeve/shielding (and every metal case 3.5mm plug actually inevitably HAS sleeve/shielding on that pin. See "TRRS" == Tip Ring Ring Sleeve). Apple did this so their iPod-et-al devices could operate with standard 3-pin headphones but for headset they would need their own incompatible "peripherals" as usual with Apple. The trick simply is to get an adapter that swaps 3rd and 4th contact.

And a footnote since neither I nor the wiki and above URL made it clear: it is totally insane to put the sensible microphone-input signal on a pin (Sleeve) that is inevitably exposed to get touched by user's hand when using a metal case plug since this will introduce all sorts of hum and (RF) interferences. And even plugs with plastic case internally have a mechanical support to crimp the complete cable into it, which is connected to sleeve of course (see photo, the longest of the 3 solder contacts of this 3-pin, 4pin are all the same, no matter what material the case) . This effectively made a convenient way for Apple to totally defeat all efforts to DIY or fix/replace a plug to connect to their devices

I am really happy the Jolla connects flawlessly to the JVC car radio. For the first time I am able to play music on the car stereo, both N900 and N9 refused to do so.
Edit: connect by Bluetooth

sorry that's also a misconception. When Nokia N900 and N9 didn't work with your car stereo then you used the wrong adapter cable, that's all. N9(00) Audio receptacle works exactly like the headphone connector of any arbitrary stereo tape recorder, walkman, mp3(-noname)-player (NOT iPod!) of the last 30 years.
Particularly the Nokia CA-75U 3.5mm-4pin<->3*RCA/cinch cable that shipped with some N900 is not the right cable to connect to any stereo amplifier (unless you short the yellow RCA plug by cramming in a conducting object, like e.g. another RCA plug)

Nope, they did for their first lumias, the recent ones reportedly implement a dual-standard that automatically switches between OMTP and the insane "US standard"
Yes, one of the official USB standards as defined in charging amendment is to short the D+/- lines.
And according to when attaching the Jolla charger to flawlessly charging N900 this is exactly what this charger does.
Also Jollaphone is charging happily from standard Nokia charger.
So maybe Jollaphone knows about the resistor voltage divider thing as used by Apple, but for sure they are using the "Nokia" standard by default.
OTOH it seems most aftermarket USB PSU simply don't connect the D+/- lines at all, they simply leave them open. So maybe it's iPhone that knows how to charge at max 500mA from arbitrary chargers, ignoring the USB specs. And there's no such thing like a wind blowing a particular direction?

Sorry, that was badly worded. By 'Latest Lumias' I meant their latest phones, the Lumia line. I have a Lumia 800 somewhere from Nokia's developer program and the headphones from that despite looking the same as those that came with my N9 do not work with the N9 but presumably do with the Jolla.
