What customers say about "Key Specs"

Fiio E7 USB DAC and Portable Headphone Amplifier

Its serves well as on outboard DAC for computers and other sources able to output digital stream to the FiiO.
For the most part, this amp does what it says it does. It does sound very good!
As for the actual sound quality, using it as a DAC from my Macbook Pro and hooking a pair of AKG K240 and I was really pleased with the outcome.
Worried wouldn't be loud enough but it's great. Highly recommend.
The FiiO E7 is a vast improvement over my ThinkPad's internal sound card. The sound has more texture, more detail, better bass and greater openness.

Fiio E9 Desktop Headphone Amplifier

Quality of construction is good. Transparent sound. All in all it's very good device.
Sound is great and works perfectly with my Pyle rebranded E7 also connected to Note 2, Note 3, 5g itouch, iPad as a DAC.
The FiiO E9 is a great entry-level amplifier for anyone looking to take the plunge into the world of headphones.
Works flawlessly as a desktop amp with the E7. I love loud acoustic music. This delivers. Very low noise threshold, very pleasing to use, cheap
I found there are lacking bass and fullness with Grado SR225 headphones with this DAC.

What customers say about "Size & Weight"

Fiio E7 USB DAC and Portable Headphone Amplifier

Compact, stylish & functional is what the FiiO E7 is all about.
Fit and sizes of the unit itself is fantastic. The presentation was also awesome. It comes in a small white box, clearly styled after the iPhone packaging.
This is a great little device. For the money, FiiO seems to treat you very well.
Size wise, it's about the size of a portable mp3 player. Pretty compact and comfortable in use.
It's made for the total product quality, but the size is little bit larger than the X series of Sony Walkman.

Fiio E9 Desktop Headphone Amplifier

It feels very solid and heavy for its size. I don't think it is gonna break if fall once.
Versatile Little Box. Well build solid construction and comfortable is use.
So, I think this is probably a killer little amp if you're running music thru a computer or MP3, etc.
Its somewhat large. When i think about DAC I imagine noteless little device. But this one isn't like this.
Feels that the DAC is a little fragile and vulnerable with connected E7 amp.

What customers say about "Features"

Fiio E7 USB DAC and Portable Headphone Amplifier

The E7 also has a line level input. The main reason for most people to use the E7 as a headphone amp.
I would also like to talk about the OLED display. It is real functional and looks great.
There's only 4 buttons, and it's easy to navigate the menus. I do like the OLED display a lot.
There's no way to shut off the display when it's not in use. This unnecessary battery drain problem though.
The specs say that the internal lithium ion battery will provide 80 hours of use. I get about 5 hours at an average volume of only about half of max volume.

Fiio E9 Desktop Headphone Amplifier

Solid structure, nice finish and appealing to look at. Controls and smooth and easy to use such as the volume.
The volume/power dial is fantastic and a real pleasure to turn up and down. The headphone jacks are solid and all connections are tight.
It gives great sound and the volume control on the front makes it very easy to adjust sound levels to compensate for differences in sound levels of the recorded music
The volume knob has no tactile feedback at all. Just a somewhat loose spinning wheel. It also makes a bit of sound as the edges of the knob.
Its requires external powerful supply. Would be nice if it ran off usb power.
