Audio Custom In-Ear Monitors IEMs Quick Thoughts Thoughts

A Short Tour of Hidition’s HQ in Seoul! (And brief impressions of their CIEMs)

New Tears 6 Pro (NT6 Pro)

Six balanced armature drivers with a passive five-way crossover

Sensitivity: 107.7 dB
Frequency Response: 10 Hz – 18 kHz
Impedance: 45 Ω

Very technically-capable CIEM. The NT6 Pro has a mild, V-shaped sound with enhanced bass and treble. Bass rumbles deeply, and the treble is sparkly and well-extended. Detail recovery and clarity are top notch, comparable to my beloved UERM. The mild recess in the midrange frequencies will be a bit disappointing for the vocal enthusiast, but overall I was very impressed by the NT6 Pro‘s technical abilities.

New Tears 6 (NT6)

Six balanced armature drivers with a passive four-way crossover

Sensitivity: 107.3 dB
Frequency Response: 10 Hz – 18 kHz
Impedance: 27 Ω

Personally, I like the NT6 more than the NT6 Pro. With a little more balanced sound than the NT6 Pro, the NT6 achieves a warm, neutral-ish sound, with mildly-boosted bass. As they were more mellow sounding, they were sounded great with acoustic tracks I’ve demoed them with. In terms of technical capability, I rate them just behind the NT6 Pro, but not by a big margin. If you are a fan of a slightly warmer sound than the NT6 Pro, the NT6 is your CIEM.

Viento Reference (Viento-R)

Now, these are very interesting. Like the new Noble FR/PR IEMs and the Vision Ears VE6 XControl, the Viento-R has two small switches on each side of the CIEM, one for bass boost, and one for mid boost.

According to the marketing director, this switch system was created in order to enable the Viento-R to be custom-tailored to the tastes of a wider range of customers. The switches are recessed, so you need something pointed to toggle them on and off, so as to prevent accidental flicking of any switch.

Even with both of the switches set to off, the Viento-R is quite a musical CIEM. It has boosted bass and mids, along with smooth, yet well-extended treble. The marketing director listened to my SE846 with treble filters and told me that they were surprisingly similar to the Viento-R; I found his statement to be true as well. With very deep sub-bass and rich mids, the sound signature definitely reminded me of the SE846, just with tad less bass and more extended treble.

The switches in reality only alter the bass or midrange by a few decibels, so don’t expect a night and day difference, but the differences are still quite noticeable and audible. So, if you like a slight boost in your sub-bass or mids, you’re in for a treat with the Viento-R. Detail retrieval and clarity remains fairly average, lagging slightly behind the NT6, but I am convinced that the Viento-R is the most musical of Hidition‘s offerings.

      1. Do you have a preference out of the NT6-PRO and the Viento? I’m trying to decide between the two, but they seem to have quite different sound signatures. Is the isolation not as good with the Viento?

  1. I personally prefer the warm colored sound of Viento. If you are looking for warm and mellow sound, Viento is the way to go. If you want fun V shaped sound, NT6-Pro is the way. Isolation is pretty much the same for both.

  2. Hello, so new Viento-R is not even slightly bright sound? I was interested in NT6-PRO, because most CIEM are warm or dark and I wanted something with a little brightness. Is Viento-R as good as Shure SE846? Thank you.

    1. You can probably say that with the switches off, it is brighter than it is dark, but it’s clearly less bright than both the NT6 and NT6PRO. The Viento is excellent and it is no worse than the SE846 in terms of technical performance but gives you the tuning switches and added isolation as opposed to the exchangeable filters. You’ll have to decide what’s better — the fit and comfort of a CIEM or the convenience and resale value of a universal.

      1. Thank you. Are the mids recessed in the Viento-R? Or are they in line with the other frequencies or forward? What kind of source did you try it with?

      2. No, the mids are never recessed. The midrange boost switch will make the mids a little thicker and a little more forward. Sources: LG G3 (Victor) & Sony F886 + FiiO E11K (Mr. T)

  3. Didn’t know Hidition had a new earphone. So the bass switch boots the sub-bass a bit, but what part of the mid-range does the other switch boost? Does it push the vocals forward? Thanks in advance for the response

    1. The second switch does push the vocals forward, but mostly makes it sound thicker and fuller. Of course the drawback is that clarity is slightly reduced and the whole signature begins to skew toward warmth a bit as well. Both switches are more subtle than anyone might think, but the aggregate effect is still quite noticeable.
