FiiO E7 Headphone Amplifier/USB DAC Review

Our friends at the FiiO headphone- and mobile player paraphernalia company sent me their newest oeuvre for reviewing – the FiiO E7, a portable headphone amplifier and USB sound adapter (also often incorrectly called pars-pro-toto ‘DAC’, as the cool people like to refer to sound interfaces), successor of the popular E3 and E5. Unlike some other Chinese manufacturers that cater to an ‘audiophile’ demographic, FiiO managed so far to release products that are of quite high build quality and having good performance while still keeping a fair price. To put it bluntly – in my opinion FiiO doesn’t rip their customers off unlike some other manufacturers, and the E7 is yet another case in point. Despite the E7 being the least inexpensive FiiO product so far, the not so high asking price of around $80 gets one a quite nifty and versatile audio toy.

Three Stones MiniBox-E+ Review

Our only amp review so far was about the $7 FiiO E3, so it might be time to step things up a bit. Enter the Three Stones MiniBox-E+.

Peculiar brand name… After a bit of sleuthing I’m still not quite sure who is behind the brand “Three Stones”. It seems to be a Chinese one-man project that’s being distributed internationally by US-based Hi-Fi vendor Head-Direct. Three Stones have been in the business for quite some time with several portable amp models, and the MiniBox-E+ I’m writing about in this review is their current top-of-the-line model.

Read on after the jump – especially if you feel the need to drive your 300 Ohm phones properly on the go.

FiiO E3 Headphone Amplifier Review

I’ve been using this incredibly tiny and cheap headphone amp we already mentioned earlier for a few days now and I’m really impressed with its performance. My expectations weren’t exactly high when I ordered it, but after testing it with several phones I’d say the Chinese FiiO company managed to design a really fine product.

The amp’s construction is very simple. It’s powered by one AAA battery and sporting only a 3.5mm input jack that connects to the headphone output of an MP3 player and another 3.5mm output jack where the headphones plug in. The output also acts as the power switch. A red LED lights up when phones are plugged in, indicating that the amp is active. Rumor has it that a National Semiconductor LM4917 op-amp works at the core of the amp. However, this has yet to be verified.

The FiiO E3 was not designed to work with line-out connections since it lacks a volume control. However, what it does for low- (and not-so-low) powered headphone outputs can be quite nice – when one’s headphones synergize well with the amp, that is.

SanDisk Sansa Clip+

The Clip+ has a fantastic little form factor; somewhat cheap in build quality but very rugged. The interface is simple and relatively straightforward. The features on the Clip are more or less average, however it supports the alternative Rockbox firmware which provides tons of additional options (gapless playback, Replaygain, playlists, Last.fm scrobbling, etc). Read the full review or go ahead and buy it.
Cowon J3

The J3 is a fantastic PMP with a very nice AMOLED screen and tons of features. It sports Cowon's trademark BBE sound enhancements, and offers a customizable user interface with strong support by our user community. You can usually find it at Amazon for the best price - and don't forget to check out our review.
Microsoft Zune HD

Sure, many of us are not big fans of the walled garden, but there are a lot of great things going on with the Zune: sturdy hardware, ultra easy to use user interface, and a media player that is worthy of Editor’s Choice. You can check out our Zune HD review or stop by our Zune forums for the latest info and gossip.
Phonak Audéo PFE

Phonak Audéo PFE offer outstanding clarity and precision; natural, dynamic mids and treble, and decent bass for a single armature in-ear phone. They handle dense, complex music very well. The PFE work well with most acoustic and some electronic music genres, but bassheads might have to look at other alternatives. They're great for sports as well, since they fit very securely. Check out our review.
Hippo VB

The Hippo VB (Variable Bass) offers a serious subwoofer for on the go, right in your head. They don’t just deliver generous quantities of punchy, textured bass, but good audio quality over the whole frequency range with decent clarity and exceptional soundstage. Exchangeable bass ports let you customize their sound to your liking. Read our in-depth Hippo VB review.
Soundmagic E10 / E30

The Soundmagic E10 and E30 are basically right in the middle between the Phonak PFE and Hippo VB - not too analytical sounding, not too bass heavy. The E10 provide a bit more bass, the E30 a bit more clarity. Both come with a very fair price tag considering the sound quality they deliver - a great choice for the audio aficionado on a budget.
