With the A5 Headphone Amplifier they continue this tradition by striving to significantly improve over our previous products the E12 series. Every last detail of the E12 series has been reworked and revamped so as to create a new headphone amplifier that not only maintains the E12 series' strengths but also rises above them for an even better product. Strong Internals Make For A Lively Listen The A5 continues to use the E12A's highly effective MUSES02 + LME49600 opamp combo. In addition all major components utilise high-precision metal film resistors. These factors along with better design and component selection allow the A5 to achieve a total harmonic distortion (THD) rating of almost 0% (lower than the E12A's by 33%) and an improved signal-to-noise ratio of 115dB. All of these factors signify that the A5 has a gain level of close to that of the E12A but has improved channel balance lower noise floor and an overall purer sound. Clean and Potent Power Clean and potent power is also extremely important to sound quality. The A5 contains a highly efficient low-resistance power management system as well as dual +/- 11V supplied power. This is a significant increase over the E12A's +/- 7.4V supplied power and gives the A5 considerable power reserve that is unheard of among portable amplifiers. Finally a +/- symmetrical power supply allows for the elimination of coupling capacitors. What does this all mean for the sound quality? Reduced distortion and increased dynamic range. All of these aspects mean that the A5 combines the best of the E12 and E12A amplifiers. Beyond just getting output power near that of the E12 with 800mW at 32 Ohms you also get the E12A's exquisite abilities in reproducing music. And with the low/high gain switch you can enjoy the A5 with all kinds of headphones from the most sensitiv. ## Features - Features - Professional MUSES02 + LME49600 op-amp combo - Lengthy 12 hours - Quick 2.5 hour charging - High voltage supply of +/- 11V ## Images ![FIIO A5 Portable Headphone Amplifier Black - Image 1](https://m.media-amazon.com/images/I/21Rt997L6kL.jpg) ![FIIO A5 Portable Headphone Amplifier Black - Image 2](https://m.media-amazon.com/images/I/31ohCdItOnL.jpg) ![FIIO A5 Portable Headphone Amplifier Black - Image 3](https://m.media-amazon.com/images/I/31ohCdItOnL.jpg) ![FIIO A5 Portable Headphone Amplifier Black - Image 4](https://m.media-amazon.com/images/I/21Rt997L6kL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A beautiful bit of kit that has made an already excellent ... *by E***G on Reviewed in the United Kingdom on 19 December 2017* A beautiful bit of kit that has made an already excellent audio player (HiFi Walker H2) even better. Using Sennheiser HD600 headphones pushed the H2 to its limits (though to its credit, it coped quite well): I hesitated whether to spend more money on the FiiO A5, but in the event this amplifier has raised things to a new level (from very high to stratospheric, IMHO). Recommended without hesitation. The only negative (not enough to reduce the 5-star rating) is, like others, I find the added bass button a bit underwhelming (though it can add a bit of life to any recordings that are less than hifi - taken from an old vinyl LP for instance). It adds bass OK, but it makes the whole sound stage rather woolly. No problem, just leave it switched off.. a bit of a wasted opportunity though. ### ⭐⭐⭐⭐ 4.0 out of 5 stars For the price - a good buy *by A***E on Reviewed in the United Kingdom on 28 April 2017* A very nicely made amplifier which I used for a while with my Fidelio X2 headphones. I has 2 usability issues with this product. Firstly, the volume control - I found I had to lift this amplifier up slightly in order to turn the button when the amplifier was on my table, and secondly, the USB connection was on the side and not on the rear which I found a little odd. The product is really bargain basement however, but in the end I returned this item and bought a Chord Mojo. ### ⭐⭐ 2.0 out of 5 stars Muddled sound and lacking in musicality *by J***3 on Reviewed in the United Kingdom on 8 October 2017* I really wanted to like this little amp as the online reviews were sparkling. But for me it just didn't hit the mark. Doing direct comparisons listening to tracks with and without the amp I found the amp lacked musicality and was quite bright. I was using Audio Technica ATH-M50 X headphones, listening to Spotify through both my smartphone and laptop. Listening without the amp I felt my toes tapping and I was enjoying the music.. With the amp I was constantly fiddling with the volume level, adjusting the gain and hitting the bass on and off to tweak the best sound. But the amp made the music muddled and the highs were very false and bright and didn't sound like true instruments. The same with vocals. Without it, vocals through my Audio Technicas sounded natural and enjoyable and real, but with the amp the vocals sounded forced and unpleasant. Sorry to all those who gave this 5 stars. Its a nice attractive piece of kit with excellent build quality and it definitely does increase the volume, but the quality of the sound output from it just didn't justify the £109 price tag. I was hoping it would enhance the Audio Technicas, not make it worse. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/48155383-fiio-a5-portable-headphone-amplifier-black](https://www.desertcart.ph/products/48155383-fiio-a5-portable-headphone-amplifier-black) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-22*
