Review: Fiio E7
Jan 3, 2011 at 5:32 AM Post #331 of 548
Aha! I got FiiO E7 last month and totally loving them. Used them with my RE0s and oh man... I was on Cloud Nine!

I didn't get time to review it thoroughly. However, I've been wondering about one thing - How to update the E7 firmware? Tried to google but wasn't lucky to find a good thread that offered latest firmware detail.

Update is not possible without a special kit from FiiO. They said you'd need to send to back for that. But if you bought it last month, it would be from the third batch which is the lastest version anyway. I haven't heard from they saying they are planning on any new version.

Firmware update doesn't make any change function wise, so there really isn't any real reason to update it.

Is it possible to use the Fiio E7 as a portable DAC, by connecting it to a portable player via the mini usb port?
 
(ie.  Iphone --> proprietary iphone digital connector --> mini usb/usb adaptor ---> Fiio E7 --> Headphones)

Unfortunately no. The only way it is possible is to connect E7 to an iPad via camera connection kit. AFAIK, the camera connection kit is not compatible with iPhone.

I have an easy question: Do I need to turn USB charge on when using as a DAC through my laptop or turn it off? I use my E7 as a DAC more than as a portable amp.

I don't think you should charge the battery unless you are going to use it as a portable afterwards, because constant charges and discharges deteriorate the batttery a lot.
 
There are online articles that concluded experimentally that storing Lithium-ion battery at 40% and at a cool temperature (charging produces heat) can ensure a longer longevity.

Is it worth it to upgrade from a GammaY1 lite>>Pa2v2 to the Fiio e7? I'll be using it with Alessandro MS1i and Etymotic MC5's. Have there been any comparisons already made to this?

Glad to hear that.
 
All of the E7's we are shipping now should come with the screen protectors in the package.
 
The screen protector in combination with the silicone case really makes the E7 a pretty rugged little device. I have one with me every day driving T50RPs off of my laptop, which are my "I don't care if they get pinched" headphones.

I'd say that's probably a downgrade. The γ1 is a probably one of the best VFMs in DACs (esp. if you DIY it) and the PA2v2 is a very well-considered amp. I would say that the combo you have is probably well beyond the E7 (not that the E7 is bad, just that the other two are so good).

Technically it comes with two screen protectors. There is a protective film that is already on the E7 when you receive it, and another one that is with the rest of the contents that you can apply yourself.
 
I was also quite surprised it came with a nice little sleeve also. I was completely blown away by the E7 in terms of sound quality, quality of the product, and all of its accessories which are included.
 
A steal at $100 imho.
 
I ordered from Micca via Amazon. Thank you!

Well, keeping the E7 charged constantly isn't good for the battery either. The right way to keep your batteries healthy is to charge it, let it go down to approximately 10% and then charge it again. By the way, Lithium-ion batteries can't be compared to the "newer" Li-poly when it comes to saving space and charge/discharge cycles.

Not keeping E7 charged. I never used the word "charged", so please don't take my word out of context. I admit the wording could cause some confusion. I said "keeping Lithium-ion battery at 40%", keep as in store, in other words, "storing Lithium-ion battery at 40%". Perhaps, an article like this would help explain the science behind it.
 
I edited my previous post to the word "store" instead now. Besides, how can anyone "keep" a device charged at a certain level? Think about it logically, there isn't a device like that that would allow you to do that because charging will always increase the battery level even if you are using the device unless the device is designed not to be used when charging. Think about laptops, for example.
