KZ ED9 Tunning Nozzles In-Ear Headphones

Disclaimers

I bought this IEM with my own money. This review is completely subjective.



Accessories

Classic KZ box content+tuning nozzles. Ok accessories for the price

Build

Ed09 is fully made out of metal and comes with a good quality (for price) cable. And it has detachable nozzle. Really good build quality.



Equipment’s used for this review

Kz Ed09, Tanchjim Space Lite, Cx31993 Dongle

Sound-Tonality and Technicalities

Ed09 still has a really good sound for the price. It has a tight, punchy, filled bass with detailed treble range. Midrange is a bit recessed but that is not an issue for me…. Because it costs just 7 dollars right now. Soundstage have a really good depth and feel. Vocals feels natural and uncolored. Air frequencies have enough amount. Dynamics are just really acceptable (bcz 7 dollars) And tuning nozzles really helps the sound. But my favorite nozzle is the bass nozzle. Because so fun to listen to and recovers the peaks in the tuning.

Conclusion

Ed09 has rivals in this price range like TRN Cs4 and Edx Lite. But Ed09 is still my fav… If you find this IEM go and give it a try. It’s just 7 dollars! Old but gold KZ….

The ED9 is overall a good and very funny iem from China. 
 
 
 
build + design:
The metal housing shows confidence and it looks like it won't break for a long time. I did like the looks overall (but the color of the cable is ugly in my point of view). No driver flex, which is very good from a low-budget iem (oh I remember you, AWEI). The cable is noting special, but the plug didnt fit very well in my Sony M4. Didn't have the chance to try it out with other phones, but  I used a bunch of IEMs with this phone and they did fit fine.
 

 
 
package + accessories:
the acoustic filters are FUN! at first. They come with 2 acoustic filters which changes the soundpicture completely, one highlights the bass and one is kinda like a reference filter with no filter at all (at least I guess so since no instructions came with the package which is a shame and a big black point for KZ). I liked the bassy one a lot more: the reference one was too boring for me (no bass, no dynamic, less fun) but IMO a lot of bassheads will like the bassy one since it surely has tons of deep and bass. It has 2 pairs of filters and 3 pairs of silicone air tips. The package is plastic and can be used as a bag if you remove the accessories from it which is a great idea.
 

 
 
SoundQuality: I spoilered it at the acoustic filters: overall I did like them very much (for 9$ very-very good SQ), a little too much deep for my taste, so be careful, if you like neutral or balanced EQ then use the other filter. The soundstage and the details very better then expected (yet again, for this price): this one is surely a fun thing to use.
 
for this price I would recommend this IEM to everyone who likes to experiment, looks for a decent, metal housing earphone or just likes a lot of bass: value/price ratio is 5/5. Recommended.

I happened to stumble upon this by mistake on head-fi and thought lets order one. 13$ there is nothing much to loose.

Packaging: Good

Build quality: Wow, did not expect that for 13 bucks. Solid Steel casing, Great solid wires and Brass Tuning nozzles.

Audio Quality:
I use my fiio x-1 to test any earbuds or headphones with some excellent flac flies (lossless music files). I usually connect my earphones to lapop and play a 20+ hour play list to ensure new earbud or headphones burn in.

I dont love extra bass in my music. I enjoy music the way it is without any altercation. So I switched onto the filter less nozzles (No User manual by the Manufacturer to differentiate between the nozzles. The one with black filter on it is extra bass)

Post a day Connected it to my Fiio X-1 and started with my favorite song, Riders on the storm (The doors), Oh man I was blown away. I was getting the feel that these earbuds gonna be my favorite ones.
I was skeptical about the fit, I get cranky when earbuds dont give a comfort fit and with 13$ i was really not expecting a good fit. (I hate silicone tips as they always give me an annoying fit. So changed the tips to Memory foam). With Memory foam tips on it, I can say they are quite comfy and give adequate noise isolation.

After playing some Jazz, played some adele songs (I love her voice and I really love good vocalists). Then turned on to MJ thriller album. I was blown away. They reproduce the sound the way it is no added bass perfect lows and mids.

I doubt they get better with more burn in, I already have played good 60+ hours and no change. As it is they are just perfect.

You cannot go wrong with this.If these were made by any other famous brand, they would be selling it for 100-150$).

Build Quality: 5 stars
Audio Quality: 5 stars
Pros: Everything
Concern: No instruction on Nozzles, Some of the members have posted concern on QC (I did not encounter any)

Suggestion: Keep good music source and quality music files

Conclusion: If you love good music and you want something under budget, here it is. T
