The FiiO M3K is a real whirlwind of a new DAP on the Audiophile market. Being the first time I’ve heard any portable player with an AK4376A inside, I am happy to report that I really like what I am hearing upon my initial impressions.
FiiO has always offered fantastic deals in the past. Naturally, this new M3K falls neatly in line with the newest generation of ultra-portable music sources in the budget tier. I am a little offset by the vertical touchpad, but I do find it refreshingly interesting and a totally new motor pattern. The stock EQ needs some work. But, what is there, is just fine and sounds good. I am impressed by the build quality and the hefty density factor in weight that the M3K offers.
Beyond pleasing visuals, the interior UI is well set up and easy to navigate. Although, the vertical touchpad is very sensitive and can scroll too fast at times. The M3K is shockingly fast with a manual microSD scan, which likely comes from the “powerful” X1000E CPU. And yes, I fully agree it is powerful.
Battery Life Impressions
For such a price, this is one of the fastest ultraportable and budget music players I’ve used in a while. The battery life is also excellent with superb standby time. It is one of the only “newer” portable players that I didn’t have to charge up after a day of just letting it sit out on my desk. FiiO claims an entire week of standby time, so I look forward to testing that. By the looks of it, the battery depletion after just one day is hardly noticeable. Great news so far and upon initial trials.
For now, I think the M3K is a wonderful little player with a good sense of tonality. Although, due to the lacking EQ functions in there, I will likely not be using it with my bass heavy IEM’s for any personal usages. But, it seems moderate enough to enjoy if you are purist and your gear isn’t specifically set up for bass.
Beyond that, I am extremely impressed by the top end offered. The treble experience is gorgeous. It feels very dense, well tailored and tonally interesting, all the while never feeling sibilant in the short time I’ve had with it so far. This is shaping up to be an excellent player all around and I cannot wait to dive further into it over the next few weeks.
