Its better. I hate inventing adjectives to describe sound such as "chilly-warm-hot-cold transwarp capable" so i operate with only "good" or "bad"

Hot damn! I'm really loving my E5! I watch a lot of series, movies and whatnot!
The HD555 is great for those things, but the E5 just gives it that extra kick it needs to be really awesome!

Here's an update on my dead Fiio E5: I left the E5 turned on and let the battery run totally down until the little blue light stopped shining. (This took a long time.) Then I charged it back up, and it works fine now. Very weird. I tested it several times while it was running down, and it had zero sound output except that it would make a very quiet click through the headphones when I would turn it on. So, what might these strange symptoms indicate? A problem with the battery charge timer circuitry, maybe?

Oh, and by the way, I misspoke when I said I bought it from dealextreme - I actually bought it from head-direct. I contacted them, and they said they would replace it under warranty. But I think I'll just hang on to it and just let the battery run down more often.

So it seems that the e5 is worth the small price. I am looking to pick up a pair of iem's for running to pair with an e5. I am using a blackberry for music by the way. I didn't want to start a new thread. Anyone have suggestions for running iem's to pair with the e5? Looking to spend $100 total for e5 and iem's.

if youre going to use iems you should get a resistor adapter, or it'll be hiss heaven.

Is anyone keeping track of how many E5 units have failed or malfunctioned?

HELP! Am I blind? I have searched this entire thread for keywords "charge" and "charging".

My FiiO E5 is just 2 days old, I have no problem with it, except when charging. The red light never comes off, I pull it out in about an hour coz I read somewhere 30 mins should be enough. I don't want to screw it up by overcharging the built-in battery, anyone knows exactly the charging time for this? I drained it only twice, the first one was out-of-the-box worked for several hours. Then I charged it and it worked perfectly fine, the red led turned off when the charging is complete. But after I left it amping for about 20hrs eventually turned off itself. I charged it right away, using my mac's usb port. The problem is, even after 2 hours of charging there were no signs.. I switched it on and off to see if it reacts but the LED just turned purple (combination of red and blue when on, red when off!).

BTW I burned it in for about 30hrs. I love the SQ!

I use a high output genuine creative charger and that takes maybe 2 to 2.5 hours then the charge light goes out i would expect it to be more with the usb to compuer method and would just leave it until its done even if it was 5hrs.(if its flat i listen while its charging)
still very pleased with mine always use it with my d2 and the ultrasones and reading inbetween the lines of some threads think it may be better than the cheapest ibasso ?????

btw just had a look at my charger and its putting out 1000ma dont know if this is recommended but it works great

First, depends on the power rating of your USB port (Self-powered / PSU-powered) and how depleted your battery is, it might takes different amount of time to fully charge your E5. One thing that won't happen to your E5, assuming it functions normally, is overcharging. FiiO has an overcharge protection chip built-in to prevent the battery being overcharged. When it is fully charged, the chip will just turn the charging circuit off. I have left my E5 plug-in all night with out any problem at all.

Second, E5 has no big caps inside, so there is absolutely no need to burn it in.

Third, Li-ion battery used in E5, as well as any Li-ion battery, does not suffered from memory effect and allows you to recharge it anytime with out worrying of what level of power was left inside. One thing you should do is to recharge it as much as you can. Don't always let it depleted to minimum - you will do more harm and shorted the battery life that way. Occasional full depletion is fine. In short, frequent full power cycle (max to none) is not good for Li-ion battery.

Any USB adapter b/w 250mA and 1A (1000mA) is fine. Beyond 1.5A is not recommended as it exceeds USB standard.

So I just picked up some JVC HAFX66B earbuds. I'm gonna use them for the gym a bit and walking around campus, would it be worth it to pick up the e5? I'm using my blackberry as the music player.

I wonder if its safe for the FiiO knowing that Creative supplies a rather different amount of current. The longest charge I've gone is about 2hrs, that concludes I made the right move. Surely that gave me a relief, thanks!

That's good to know. I am very careful with small gadgets because I know they are quite fragile and can damage other electronic devices (like mac or netbooks). I don't wanna fry my first amp and most certainly the macbook or the dell mini! Interesting, ironically, I was thinking quite the opposite. My memory ( browsed the product manuals in the past) tells me that Li-On used in mobile phones are supposed to be drained before charging and they were much lighter and more powerful than Ni-MH counter parts. I had this idea that the later was tougher, heavier and can be charged anytime (was interested in Tamiya racing cars before). But it seems to me I had totally gotten it all wrong.. Anyways, enough of the babbling, I would still listen to your advice. More importantly the E5 works and I am happy with it. Thanks!
