Until the Fiio E5! Finally, a 150mW, portable, high-fidelity headphone amplifier that -- connected to the right components -- returns your music to it's full dynamic range and frequency spectrum. My Sennheisers roar! Thumping bass! Sizzling treble! Quiet soft passages and deafening loud passages ... all from a rechargable gizmo about the size of a matchbook!
But it is what it is. The Fiio E5 does not have nearly the amp to drive my full-size 150Ohm Sennheiser HD-525s to their abilities; alternately, hooked up to my son's Ipod Touch (which apparently has quite a bit of output power to begin with) and his preferred earbuds I could not notice a distingushable improvement in sound. But for an underpowered portable CD or MP3 player and a mid-sized set of high-fidelity headphones ... the Fiio E5 is a godsend. Hear what you've been missing! And for under $25? It's a no-brainer.
For $20 plus shipping, I figured I'd give the FiiO a try. If it didn't work, just return it, right? So it came today, and I gave it a try with some of the problematic tracks on my iPod. First reactions: enough volume boost (barely, but enough) to make the problem tracks listenable, and to drive the HD600's to more than comfortable levels on most music. I have the volume on the E5 turned up all the way, and use the touch-wheel on the iPod for volume control.
Second, despite some other reviews here and elsewhere, there is NO discernable hiss or noise from the FiiO E5, either idle or with music playing.
Third: Bass boost works as advertised. If you have phones that don't give you good bass response, this will probably fix your problem. The HD600's have great low-end, so I'm running the E5 set to the OFF position.
Summary: well worth the money, and worth a try if your music player is working too hard to drive your particular headphones, or if you need the bass boost. I detect no degredation of the sound with my iPod. Just for fun, I hooked it up in series with my Home Headroom amp, to see if I could hear a difference...yep, the E5 blurs the extraordinarily good sound from the Headroom just a bit. But, then, that's not what it's for, is it? It's NOT a high-end, multi-$$$ amp, just a way to get a bit more performance from your portable music player. For that, it works just fine!Read more ›
The reality is that the FiiO E5 fits in with only a select grouping of headphones, ones that have relatively high impedance ratings. I didn't know that going in, but after dogged listening sessions with all sorts of cans from my own stash--from basic OE units for the Zune HD and iPod Touch to my usual portable-use Sennheiser IE-8 and Koss PortaPros to my in-home use Senn HD-650 and HD-800 and many units in-between, it was clear to me that the E5 doesn't have enough power within it diminutive chassis to do the usual low impedance portable head and earphones any tangible favors. Using either a Touch or Zune HD as the source, the E5 struggled with pretty much every set of cans that had a rating of under 100 ohms or thereabouts. It wasn't until I hooked up my HD-650 (300 ohms) with its own set of aftermarket cables (Stefan Audio Art Equinox)--one of the few high impedance units I have left in this world of low impedance portability--that there was any measure of uptick in SQ. Here at least the E5 was making a positive difference, where as with the Shure SE530, Senn PX-100 and others it just sounded wretchedly overmatched and severely underpowered.
With the HD-650 (and later the HD-800, what I consider the best set of cans I currently own), the E5 perceptively improved low-end depth and punch, while also smoothing out midrange sound and adding enough power to heighten sonic detail into the upper frequencies (well, at least as high as my near five decade-old ears will go these days).Read more ›
I actually bought this for use with Amazon Prime since they do not have CC (Closed Captioning). This unit is the only amp I have ever bought for use with my headsets so I cannot make comparisons, but for amplifying volume so that I can actually hear the dialogue, this unit is FANTASTIC! In fact, for Prime shows, it is so loud, I have it on the lowest setting to hear comfortably! For movies elsewhere on the Net, I've had to crank it up a few notches for those that were ranked a low score due to low volume but I hear everything!
I do not hear any hissing, pops or anything that some other reviewers have complained about but then again, maybe their better hearing picks up these imperfections. I do not hear them however. The unit normally goes for $30 but w prime it is discounted about $10. I bought it before I had Prime back in June 2011 and it was worth all $30! One thing I do notice is that it works best with a headset with one jack and can be a little glitchy with headsets with mic/headphone dual jacks - sometimes it works with duals and sometimes it doesn't so be aware of this.
The unit is small- about the size of a paper matchbook, is very light in weight but made of high quality material. The surface is slippery and the clip is sturdy but slippery also so it may have trouble actually staying in place. My advice is to clip it on the inside of a pocket so that the clip is on the outside and the unit in.Read more ›

The POWER and CAPACITY for this little amplifier is quite astonishing. I has a clip integrated. It charges via USB. You can use it without the charging wire. Read morePublished 8 months ago by Love2Earth: I mean IT
I was using this for speakers on a ham radio. Was no louder, turned all the way up, than just passive speakers plugged in to the radio directly.Published 9 months ago by Allan
Nice build quality, some noise at high volumes but i love the bump in the bass so I recommend this little amp
This item has lasted me years. Boosts tablet streaming media sound so that multiple headsets can have full sound when watching movies with my wife.Published 10 months ago by Stephen Opal
This little amp works ok, wish it had a little more oomph to it as I like to listen to my music LOUD. Probably why I have to turn it up.......Published 12 months ago by Mike McCormack
While it puts out a decent amount of power, this amp colors the audio in a bad way and has hard to use buttons paired with a shoddy EQ switch.Published 14 months ago by brandon lasater
