post #226 of 367
I just changed batteries using nothing but my clumsy thumb and fingers. No biggie. Also my oversized Soshine Li-ion batteries fit in quite easily. There's lots of play in the metal springs. If those fit, I figure just about any 9 volt will.

Hi Cooperpwc,

I was searching for a good 9v 600mah LI-Ion battery and saw this Soshine battery.
How is the sq with this battery? Have you compared to other types of battery or brands?

Trying to decide either to buy Soshine 9v 600mah LI-ion or 9.6 v 230 mah Imedion.

I use IEMs like AKG 3003, F4 Kaede or PF X-G with PP. i read somewhere that recommendation for PP with IEMs are the high 600mah for sq.

Thanks

You are too concern with the battery type.  Just enjoy the amp.  BTW, most li-ion is rated at 8.4 Volt at full charge not 9.0 V.  9V is a battery type not an actual volatage.  NI-MH is capable for more voltage though.  If you are using harder to drive cans, go with higher voltage rating on NimH battery.

I've been using the 9.6 Imedion batteries every since I've had the Pico. Unfortunately, the 4 initial batteries I picked up were DOA after a few weeks, so I'm still waiting for my replacements. They definitely have more juice than the ones I'm using now. Right now I'm using the new HiTech Li-Poly 9Vs. They have significantly less voltage (avg. rating of 7.4) but they are rated at 720mAh, which is the largest I've seen thus far. I've been using them for a few days now (probably 5-6 hours a day) and they've lasted, and I expect them to last longer. If you are using just IEMs with your PP and longevity is a priority (it is with me) I would recommend either the Li-Ion or the new Li-Poly. Like Purk said, use the NiMH if you are using harder to drive full-sized headphones. Before my Imedions went bad, the most I got out of them were 14 hours. Since, they have not been able to hold a good charge so they die out very fast. I would suspect 15 max playback on the Imedions.

I have had used the imedion 9.6v batt too. But now i seldom use it. I prefer to use energizer battere. It is not rechargeable but the battery can last a lot longer than the imedion. My imedion duration time is dropping after 10x charging.

Hi Purk,

Kindly ask for any impressions regarding the difference between duracell (standard) vs Maximal Power.

Thanks

Reading from the posts seems like Imedion have some qc issues that are affecting battery life.

They are not cheap though

Less than 10x? Crazy!

I better look at other brands.
Perhaps Maximal Power

I have not made any comparisons but I can say that the Soshine are working great. SQ is excellent. This amplifier is producing deep powerful well-controlled bass with both my Heaven VI and KAEDE. The sound overall is fuller; the Classic headphone out thin and boring by comparison. No time for full impressions but I am amazed.

 

As for how long the amp runs on the Soshine, I have no idea. I must be well over 20 hours and they are still going strong.

They are made by Maha the same people who made Powerex brand.  I had the same problems with my 9.6 V 230mah as well.

I might buy Shoshine then.
Thanks Purk

Inlove eveything about PP and hope the sound will cover all types of IEMs that i got.

Thanks cooperpwc

The Soshine's finally ran out. I didn't time it but if they reached 30 hours I would not be surprised. Glad to see that battery death was instant and accompanied by loss of the power light - no slow deterioration in SQ. This fast death is to be expected with Lithium-ions and I like it.

 

Swapping batteries is indeed simple. Fresh set installed in about a minute and I am good to go for another 20-30 hours.

 

The Pico Power is a bass monster with IEMs. It is not some crummy bass boost or skewed frequency response; it is clean power that affects different IEMs to different extents. Across the board, anyone who thinks that IEMs don't change much with amplification has to try this amp.

Complete change of plans. The UK retailer still not nailed down MK3 B+ partnership so have ordered Pico Power. Do not congratulate me, what I need are your donations to cover the VAT and customs fees triportsad.gif etysmile.gif

post #240 of 367
I am wondering is the mk3plus still carry that noisy hiss or not....btw i have ordered one my self. Hopefully they fix the hiss problem rather than just a battery improvement.
