Sound Analysis

Lows

The HE150 Pro has a good amount of sub-bass extension with a quick rumble. It extends decently and the bass is smooth. I find it rather neutral. There is a good decay to it and each bass note is presented effortlessly. The bass texture is rendered well with a soothing feeling. The mid-bass does not have a great slam to it. The bass is clinical with a good extension to it. The quantity may be lacking for some though.

Mids

The midrange on the HE150 Pro is rather neutral. The lowers mids has a decent amount of body to it and sufficient to tackle male vocals. The upper mids are slightly boosted and it aids in the overall definition of the midrange. I find the midrange to not be congested. It is clean in its presentation. It definitely packs a good amount of details. The midrange is controlled and smooth. Resolution is good with decent layering.

Highs

The treble is extended great without any sibilance and harshness. The amount of air presented at the top end is sufficient. There is a slight sparkle to it. I find the presentation to be quite smooth and there is hardly any aggression. It is soothing to listen to. One can probably listen to it for a long listening session. For those who crave for more bite, I feel the sparkle may be insufficient. The overall definition is good with crisp.

Soundstage

The HE150 Pro has a good width and depth in the soundstage. The expansion is very natural. The depth is not too close. The overall positioning of vocals and instruments is good. There is no congestion and it makes the HE150 Pro operates in an effortless manner.
