FiiO E6 – Portable Headphone Amplifier Review

FiiO is a relatively new Chinese company founded in 2007 which has gained recognition in many countries worldwide. The reason for this from what i see is the fact that they provide relatively cheap and affordable products with performance comparable to the bigger manufacturers. They provide a range of audio products with their portable audio amplifiers being the most popular. After reading up about the FiiO E6, i quickly became interested and found a good deal on Ebay and purchased it immediately. Here is my review.


On first inspection, the amp is quite small but you you soon realize the controls are quite easy to use. I have used this amp with both my Razer Kraken headset aswell as my Razer Hammerhead In-ears. I am no audiophile but i do appreciate and know the difference between sound quality and this amp definitely proves itself in this field for a relatively inexpensive priced product. The amp additionally allows you to select one of three different EQ’s. I personally have found the second EQ setting (Blue) to be the best as the first EQ setting (Red) to be overpowering in Bass and lacking Treble unlike the prior which seems to be perfectly balanced. the third EQ (Violet) simply mutes sound the signal a little bit by -3 to be exact. The built in lithuim battery is said to last 10 hours which is adequate in most cases along as you don’t forget to switch off the power when the device is not in use. This amp increases the loudness of the sound output quite dramatically so i ussually have the amp volume quite low most of the time. The possible downside to this amp that i have found is the static sound which can be heard when the volume is set too high on the device which seems to be heard only when no music is playing. this effects intensifies when the device is both charging and used at the same time. Other than that, the build quality is great and this amp will most definately leave you impressed if you are seeking a upgrade of sound quality and loudness with your headphones/earphones. This product can be purchased many places online for roughly $40 USD.
