Alpha takes a departure from IEMs in this price range, which generally tend to be all about bass and nothing else. With Alpha, it is mostly about mids. It has decent clarity for a $15 IEM, but won't be competing against better IEMs for sure. The bass has comparable mid-bass quantity and a bit more extension than the ProAlphas, but sounds slightly muddy in comparison. Mids are the most dominant aspect of the IEMs, but they are not as forward or engaging as the others in the M series. Rather, they are thick and a bit sleepy. Treble is thick with cymbals/Hi-Hats sounding very congested and does not carry much air, but has some amount of sparkle.
Sound stage is smaller and easily loses in both width and depth compared to the Pro Alphas.These are decent sounding IEMs, but with not much detail or speed to go with it. Put in another way, these deliver good sound for the price and are even good for casual listening, but expecting more than that would be an exercise in vain.
