Intro

7€ do not hurt, but in the case of the EDX it does not make also really happy to have saved money. An IEM that you don't really need and in my opinion it's better to get some more money in your hand, or take a look at the EZAUDIO D4.

Handling

Headphones, cable, and a pair of silicone tips. More is not possible, but also understandable at this price. The cable is useful, but nothing special. However, it does cost a good half of the EDX in purchasing. So you can calculate what the EDX costs in production. That one notices also with the processing, where unevenness and a larger gap dimensions are to be made out. To be honest I am surprised about the very good channel equality in frequency measurement.

The isolation is okay and the wearing comfort even very good.

Sound

The EDX is damn cheap, you shouldn't forget that, but in terms of sound you shouldn't expect too much either.

The bass is the bright spot of the EDX, even if it doesn't always seem stable and sometimes a bit dull. But it has a good punch and assertiveness, without overlaying the signature or piling up. If you look at it separately, you can certainly build a good budget IEM on it, even if the bass does not meet the highest demands in terms of quality.

The mids have one of the greatest tonal variations. Vocals and instruments lack authenticity and often drift off in shrillness. They just don't sound right and are far away from a mature sound. Audible with voice emphasis, but nothing more. Guitars have a pretty powerful and fun character and in combination with the powerful kick of the bass the EDX for Rock works even better.

The trebles are quite artificial and too much emphasized. They make the EDX sound a bit tinny and unbalanced. One cannot speak of a good resolution here. In addition they are quite uncontrolled and do what they want to do. Unnatural and a bit unrealistic, but bearable.

The stage is okay, but a realistic distribution of the musical information is limited. A little bit confused overall.

Outro

At the price of the EDX the cable (even if it is nothing special in itself) is actually the greatest value. The EDX is a little bit sloppy processed (gap size) and the sound is not a big enrichment. The bass is rather good, which is certainly not very common in this price range, since the emphasis is usually on quantity. It also brings out voices quite well without being able to reproduce them naturally.

I will not make the EDX worse than it is and for some cell phone supplements it can be a cheap alternative, but I would rather take a few euros more in my hand and put on more sound quality. For the occasional listening without claim okay, if you bring some tolerance, but nothing more. For under 10€ I would go for the EZAUDIO D4.

Legend

Haptic:

Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.


Value:
Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
