Jomo 6R Custom In-Ear Monitor Review

2

Sound:

The J6R has an airy and detailed presentation. Its tone is open and can be considered in the neutral class, but the sound is not completely uncolored. It doesn’t have a weighty presentation, but the transparency is impressive.

Low Frequency:

The J6R doesn’t have a prominent low frequency presentation. The quantity balance leans towards sub-bass that has a good texture and speed. The sub-bass tone is slightly technical rather than being musical or emotional. Hitting to depth ability is quite satisfying, even if it is not the best in terms of extension and decay.

The mid-bass of the J6R is not prominent and can be considered as laid-back. That results in a stage structure that has neutral and clean spaces; and the presentation is very airy in accordance with the treble approach.

Mid Frequency:

The midrange of the J6R has an open tone and a terrific transparency. Some may find it a little bright pursuant to the source used, but the sound doesn’t turn into an artificial presentation. The midrange has more presence than the low frequency, but it doesn’t have an aggressive style in terms of the location on the stage.

The average note thickness is slightly on the thin side that provides a very good transparency and cleanliness in accordance with the general tone. Overall, J6R has a very good resolution, even if the lower harmonics is not the best amongst.

The JR6 performs well in upper midrange; notes are neither unnecessarily thin nor bright. In general, monitors that sound with open or bright tone have artificial note releasing problems in upper midrange. The J6R provides a good control in releasing thin notes. In addition, vocals don’t have a weighty structure, but they are clean and the J6R doesn’t tend to sibilance much if the recording isn’t problematic.

High Frequency:

The J6R has similar prominence to the midrange that is also more prominent than the low frequency. As it is in the midrange, the highs also have an open tone without being piercing. However, the tone is not the smoothest and the most natural amongst others. In addition, the extension and resolution levels are satisfying, but it has a little stress in note releasing.

Soundstage and Separation:

The J6R has very clear and quite neutral spaces between instruments in accordance with the mid-bass presentation. The monitor doesn’t have a superb big stage, but it provides an airy positioning. The depth of the stage is satisfying and the width is enough to have a not-congested instrument placement. The background blackness and the coherence might be better, but the separation is good for its price.

    Hi, I’m looking for a neutral CIEM with a big soundstage. Hoping it sounds more musical than analytical, with a bit of treble sparkle. Looking at this, Perfect Seal AR6 and HUM Pristine reference. Would you recommend any of them? Thanks for your time.

      Hi,

      Perfect Seal AR6 may be better for your needs. HUM Pristine custom version sounds a bit aggressive in terms of the stage structure. Also, you may take a look to Lear LCM-BD4.2
