Hi, has anyone tried using a non rechargeable lithium battery, such as sold for smoke alarms, in the Voyager?

I look forward to Graham's response, being non-technical I would think it should work fine.

Can't see a problem - bit pricey though...

Do you think that there would be a huge increase in battery life though? One thing I don't like about standard batteries, having used them in a walkman, (remember them?!) is that there seemed to be a degradation in sound before the end of the batteries useful life. Is that the case with the Voyager?

In the 10+ months since I acquired a Voyager, I have changed the (Duracell) battery only once, though I only run on battery perhaps a few times a week for a an hour or so at a time.
I can't remember exactly how the 1st battery ran out (it was last year) but if there was any sound degradation it was only minutes before the battery went dead.
Anytime I'm not outdoors, I'll use USB charger or PSU.
With the right cans, its great sounding amp... did I mention modded HD25 yet? ;-)

What are these mods? I've got the Senny 575's, PX100 and Koss Porta Pro's...

These are HD 25-specific mods... pretty basic.
- Swap the steel cable for something copper (typically HD650 stock)
- swap pleather for velour pads (eases bass)
- swap split headband for HD25SP band
You get a little less detail and smaller soundstage than, say, HD650, but they have a lot more punch, are more lively and are much more forgiving of poor recording/mastering.
Even with velour, the isolation is still up with the best of mid-range closed back/studio cans and they're robust enough to chuck in the bag and take anywhere

Must say, I am pretty pleased with my 575's. First full size cans I have owned. I am sure there is better but these will do for now. I would still be interested to know more about the likely outcome of using the Lithium battery...

hello
i'm looking into modding my hd25's having read this. i have been told the capsules don't fit on the hd25sp band. i'm assuming they do as you have done so...do the fit on ok?
thanks

Its kind of one of those things where it certainly doesn't look like the 25-1 capsules were designed to fit on the SP headband as the fittings are different to the SP capsules but they do fit well and very firmly, so the ratchet doesn't move too easily (as can be the case on 25-1).
It does require a little more force to get them on the headband but after the first couple of goes, you;ll get the technique...
Good luck. Enjoy. I find the SP headband gives a better angle on my ears for sound and isolation.

Thanks for the additional info, I'm going to give it a try
