Any news on the wired over ear headphones FT5?

Just found pictures of the replacement. The Blue battery was the new 2100mah battery from Robert. The other is the original.

That's right. Remove 2 screws and push out far enough to replace the battery. Reuse the tape around the old battery. The batteries have a connector so no soldering involved. Push back in and install the screws. Quite easy compared to some replacements.

Lazard, The original battery in my 5TX was a Cameron Sino model CS-IPOD4HL. It was a 1200mah battery also used in the Apple 4th gen IPOD. I later bought a 2100mah battery from Robert and installed it in the 5TX. The 2100mah battery didn't have markings on it so I don't know where Robert got...

I have the Blox ANV3se and Blox YIN and use them occasionally but I mainly use Willsound MK2, Cypherus Campfred2 and ToneKing TO400.

I can't remember if the Black and Blue themed firmware was from Teclast or some private programmer developed it, I just know I liked it a lot better than the stock pure and simple Nationite firmware. I'm not sure I understand what you mean when you say "I guess I have one" One sflo2, one T51...

I have v2.3 Black and Blue themed firmware from the Teclast T51 which is different than the Pure and Simple themed version from Nationite. The Teclast T51 is the same device as the sflo2 and uses the same firmware. Also have the firmware load tool with USB drivers, both of which you will need...

Does anyone know the status of the 6NX/6TX development? I emailed Robert in December asking about the status and also that the headstage forums were down and all he replyed was that the forum software needed to be reloaded but nothing about the status. Well here it is over half way thru January...

Has anyone had trouble with the pulsar light on their units? I received my X7 mark ii yesterday and the light was very dim but was pulsing. I went into settings and set the "lit" option under "working" and then looked at the brightness setting and it was already at 255, maximum value so hit ok...

Here is a freq response for the 5TX.

Riolist2, I agree track ordering is bad but you can at least arrange your music on sflo2 in alphabetical order using DriveSort.  You can get it here-   https://www.portablefreeware.com/?id=2614

The universals have big bores,  approx. 5mm.  I use the Japanese spinfits found here:  http://www.ebay.com/itm/New-Spinfit-Tips-Authentic-Spinfits-2-pairs-S-M-L-3-sizes-Japan-/271811763701?var=&hash=item3f493e5df5:m:mU0ULxix6WRtcd5Dd_tCPbA I think they are much better than the foam ones that...

I also ordered the U6 (and a B1 module) a few days ago and was told to expect about 2 weeks to ship but got an email today saying my order shipped today!  I'm getting excited!!

Here is the user manual showing how to connect the cable.   https://www.64audio.com/img/1964OwnersManual.pdf

I use the Yuin PK1 with the ZX2 and it gets way loud enough.
