Sound Analysis


The F300M has a great sub-bass extension with a quick rumble. The mid-bass presents itself in a laidback manner. The slam is moderate and there is a slight punch. The bass has a good control and it is tight. Decay is moderate and the bass note is expressed smoothly. Bass texture is generally smooth. The bass nature takes on a warm and smooth approach as it is being expressed gently. The transition from the lows to the lower mids is smooth.


The midrange operates in a clean and transparent approach. The presentation is slightly technical. The lower mids on the F300M has a good amount of quantity to it for the presentation of male vocals. The upper mids are slightly forward with a decent amount of body to it. Female vocals benefit from the forwardness but with more body, it will be more organic. Definition on the midrange is quite clear. There is a good level of details retrieval. Overall, the midrange is musical and soothing.


The treble is extended greatly with a bright presentation. There is slight sibilance and harshness when paired with bright sources. There is no graininess in the treble and it is being presented with energy. The crisp is existent with a nice sparkle. The air at the top end has a good amount and this helps to reduce the congestion in the sound. The overall presentation has a good combination of air and energy. Clarity is good with a high level of details retrieval.


The F300M is able to excel in both width and depth. There is a natural expansion in its width to improve the positioning of vocals and instruments. I find the depth is rather good. There is an open feel to the overall sound.
