KZ ED9 Super Bowl Tuning Nozzles T Shaped Driver Monitoring In Ear Headphones HiFi Earphone High Resolution

AttentionㄩWhite Box and Black plastic box Packing send by random!! please understandㄐ

The ED9 earphone is not just an exaggeration. All three frequency ranges are balanced. Treble is smoothㄛ mids are not crowded and bass is not boomy. With provided sound tuning nozzlesㄛ allowed users to tune the sound to their desire. Shining silver surfaceㄛ simple and textured.

1. Innovative T shaped pole piece driver unit

In traditional driver the interior is not closely boundㄛ causing the sound to be less coherent and bright. The built in magent will cause the driver diaphragm sag down over timeㄛ worsening the sound. The all new driver unit effectively eliminates the negative pressure in driverㄛ providing clearㄛ soft feel of sound and better extension of vocals.

2. New vibrant PEK diaphragm

The diaphragm as earphone's vocal cordsㄛ plays a decisive role of sound quality. ED9 choose high end PEK diaphragm. Compared with ordinary PET diaphragmㄛ the PEK diaphragm is lighter and thinnerㄛ  faster vibration frequency. With extremely sensitive and fast response forceㄛ the ED9 show a more pure vocalsㄛ dynamic texured bass.

3. Upgrade tuning nozzles

ED9 tuning nozzles have an all new design than GR and other earphoneㄛ balanced and bass nozzles have a better sound effect.

4. Super bowl augmented mids sound effect

Innovative design nozzles which end as bowl. Improves the crowded mids' drawbacks of traditional sound chamberㄛ improve width of sound frequency range. Mids are more natural and coherent.

5. Musical instruments level acoustics brass housing

Many musical instruments are made of copper. Copper has high rigidityㄛ and could further reduce sound degradation. Enhance the resonance effectㄛ the tone is clearer and brighterㄛ reproduce the fresh thorough and extremely dynamic sound.

ED9 with bright silver chrome plated surfaceㄛ simple and textured.

Arrived in a small plastic boxㄛ it had a very basic cover graphics and a detailed spec on the back. Under the cover it had a nice display presentation with a foam cutout and ED9 inside of it. Though it was minimalisticㄛ for such low price KZ actually included a set of 3 hybrid eartips (S/M/Lㄛ hybrid design with a red core) and a set of 2 filters! Yesㄛ hard to believe but this design accommodates replaceable metal nozzle-filters that screw into the shell of headphones. And as a bonus there was an extra pair of hybrid eartips used as a "holder" for 2nd set of filters.

Nowㄛ more about ED9 design. Starting with a cableㄛ this is something you wouldn't expect from a "budget" IEM. It has a quality gold plated L-shaped connector with a nice strain relief. The multi-colored twisted wires are inside of a clear rubbery shielding which is soft and easy to manage without getting tangled too much. Y-splitter is small and rubbery with a nice strain relief around all 3 points of wire connection. Right side of the wire also has inline remote control with universal multi-function single button and mic right next to it. You don't have to worry about compatibility of volume control (Android vs iOS) since those buttons are not presentㄛ but a single click Play/Pause/Call works flawlesslyㄛ and double-click skips to the next song with my Note 4. The wire goes to a metal chrome plated shell and has a nice strain relief at the attachment as well. As you can seeㄛ a lot of thought went into the cable design and durability of every joint connection. The shell itself is very slick and has a little bit of weight to it. Considering that and a fact that you can only wear it wire downㄛ you do need to pair it up with a set of eartips that give you not only the best seal but also a grip to hold these IEMs securely inside of your ears. The shell itself has multiple air vents including a pinhole next to the attached wireㄛ the other one at the base of the nozzle filterㄛ and two large wire mesh covered ports on the back of the shell. Combinedㄛ all this contributes to an open airy wide soundstage and at the same time a mediocre isolation. Alsoㄛ top of each earpiece has a clearly spelled Left/Right marking. Microphonics effect was noticeable when cable brushed against my shirtㄛ but it wasn't too bad.

When it comes to a soundㄛ let me reassure you that included two pairs of filters are not a gimmick. When you look closerㄛ they have a very distinct designㄛ a slight difference in length and finish (faded brass - neutralㄛ shiny gold - bassy)ㄛ and shiny gold nozzle-filter even has a foam insert filter. A difference was very noticeable between these two filters that definitely contributed to shaping of a sound signature. Moving forwardㄛ I will refer to "bronze" and "gold" in order to distinguish which filter I was using in my listening setup. ED9 (bronze) has a neutral sound with slightly mid-forward signature. Overall it's bright and detailed sound with a wide airy soundstage that also has a nice depth to it. Bass is neutralㄛ tightㄛ and punchyㄛ with a good extension and characteristics of being able to hear it instead of feeling it. Mids are clear and brightㄛ slightly forward which could be an artifact of my perception. I would also say that mids are a bit on a thin sideㄛ almost close to analytical in natureㄛ but not harsh. Treble is crisp and brightㄛ and with a nice extension. ED9 (gold) has a more balanced sound with an enhanced low end. It still has a wide soundstageㄛ but not as airy due to decreased level of brightness/sparkle. Low end now gets a nice sub-bass extension accompanied by a strong punchy mid-bass. Mids transform themselves with a little more body and feel a bit pushed back behind low endㄛ but not in a recessed way. Lower mids are still on a thinner sideㄛ but upper mids are warmer and smoother. As a consequence of thatㄛ they lose some of the details in comparison to bronze filterㄛ but do remain clear. Treble is crisp and brightㄛ and has a nice extension though a bit attenuated in comparison to a setup with a bronze filter. Since majority of my other IEMs are either balanced or have an enhanced low endㄛ I figured for comparison I better use ED9 w/gold filter. Alsoㄛ since I was going through so many different comparisons between ED9 with different filters and ATE and my other IEMsㄛ the comments are relative to one specific headphone as noted below in comparison. Alsoㄛ my IM50 has a silver-plated replacement wire from Lunashops. ED9 (gold) vs IM50: ED9 has less aggressive sub-bassㄛ thinner lower midsㄛ slightly less forward upper midsㄛ a brighter treble with a bit more extensionㄛ and a wider soundstage. ED9 (gold) vs VSD3: VSD3 has less sub-bassㄛ brighter and leaner mids with a little more detailsㄛ and actually upper mids/treble is a little harsher and grainyㄛ a little better treble extensionㄛ and a soundstage with slightly less width. ED9 (gold) vs KC06A: ED9 has a similar sub-bass but a bit less mid-bassㄛ smoother mids (where I find KC to be a bit harsh/grainy)ㄛ treble has a touch less extension and not as crispㄛ also ED9 has a wider and a deeper soundstage. ED9 (gold) vs Pistons 2 (w/filter mod): P2 has more mid-bass slamㄛ a bit deeper sub-bassㄛ mids a bit brighter and harsherㄛ and they have a similar treble. EDSE vs ED9 (gold): ED9 has a very similar low endㄛ smoother midsㄛ a touch less of treble extensionㄛ and a similar soundstage.
