Has anybody received the e11 off pjbox yet ?

 

[shotgunshane]

Never did a full discharge, no such need so far and don't want to try it (*alway avoid full discharge on Li-ion battery as much as possible). I did fully recharge the E11 a few times now, and have no problem on turning it on. In fact, I left it charging on my PC overnight and have no problem.
 

I would assume the e11 cuts off before complete discharge then? Possibly he has a defective battery?

We have not send the E11 now, but will send it on next week.

Not know yet, we are testing now, but it will be solved before we send out E11 for sale.

Would this amp be good if I use an iPod touch 4th and westone 4?

Would this amp be beneficial for iPod touch 4G + ck10?

if you use E11 with iPod, it should increase the sound quality, but hard to say if the improvement is noticeable because it depend on different people.

Sorry, we need to make sure the quality is as good as possible, sorry for the delay.

how does this compare to ibassot3 and cmoy royal(with the two big golden cylinders).?. 
 
thanks
 

Much better than the cmoy royal (if mine is the same thing from Robert), and slightly better than T3D.

BL-5B (as in all cellphone battery) has over-charge and over-discharge protection built-in. The cut-off discharge voltage is about 3V (can down to 2.7V depends on manufacturer). Supposedly the battery will auto cut-off when it drops to 3V to protect the Li-ion battery from internal damage. But in rare occasion (overly fast power draw, overly cold or hot temperature, long idle etc) can cause the internal voltage to drop below 2.7V. Once it is below the over-discharge voltage, the protection circuit will actually prevent the battery from being charged again - in situation like these, you can put the battery into the charge for a longer period of time, and most of the time the charger will force charge the battery enough to fully recover the battery. But if the voltage is allowed to drop too low, internal chemistry will become irreversible and the battery will just die. This is why you should never fully discharge an Li-ion battery in any situation - if you don't recharge it back in a short period of time, it will damage the battery capacity. To max out Li-ion battery life, the smart thing to do is to recharge it as often as you can because Li-ion battery doesn't have memory effect like NiCd battery. I suspect Mike over-drew the battery, which is why he needed to reset it to overcome the battery internal protection circuit. If that's the case, there is nothing you can do to fix the 'issue' except to have a better sense on battery management.
 
The lowest voltage I have even got on E11's battery is 3.2V (that's after 12 hrs of continuous usage on high gain, full bass boost and excessively loud volume on a 32ohm IEM), which is pretty close to the bottom end of the battery capacity. I didn't want to let it went as low as the cut-off point so I recharged it back to 4.2V, the upper cut-off point for BL-5B.

I don't think W4 or CK10 need amping. If there is any improvement, it will likely from using LOD on iPod Touch.

Thank you.
 

 

[JamesFiiO]

Thanks CieOS, I can not explain any better more about the battery.
 
BTW, we will buy a new AP audio analyser soon, and I will use some picture so prove why a amp to help increase the sound quality, sometime maybe the improvement can to be heard, but it can be measure by analyser.

Just a quick question: does it come with an 3.5 to 3.5 or I have to buy an extra cable?
