The cable that comes with the EN210 is non-detachable and it is braided with a 4 core design. The cable quality is rather good. Near the connectors, there are L & R markings on the housing to differentiate between left and right. There is a small dot to indicate the left side just by feeling it. There is a memory cable section that is enclosed in a black rubber tubing. It is still flexible and supple. Moving down, the chin slider has a circular shape and it is made of a soft rubber.

Sound Analysis


The EN210 extends it sub-bass well and there is a moderate rumble. The presentation is slightly laid-back. The mid-bass has a decent slam to it. I feel there is still punch which aids the overall dynamics. Though the mid-bass is not being expressed with a strong impactful hit, the less authoritative approach allows the mid-bass to be presented gently. The bass texture is very smooth and the decay is moderate. There is a nice tinge of warmth. Each bass note is displayed with a decent amount of weight. The bass articulation is quite accurate. Though the overall approach is not very authoritative, the smooth nature adds a nice tranquillity to it.


The midrange on the EN210 operates in a warm and smooth style. The lower mids on the EN210 has sufficient quantity to tackle male vocals. Though you will not get the extremely thick kind, it is soothing to listen to without sounding too dense. The upper mids on the EN210 takes on a balanced approach with a strong control. The forwardness has a moderate magnitude. Female vocals still sound sweet but slightly less exciting. This showcases the finesse in the midrange control.


The treble is extended moderately and it sounds clean. There is no sibilance and harshness at all. It is expressed in such a smooth manner. There is no sparkle which can help in providing energy. However, the way in which the treble is presented allows a fatigue-free listening, It packs details and there is a good amount of air which helps to lighten the presentation. I find the control on the treble to be tight.


The EN210 has a good natural expansion in its width and it sounds very realistic. There is a nice depth with the space rendered at the front. The positioning of vocals and instruments is precise. EN210 has a great open feel without sounding congested.
