It's vernal. Colourful meadows, bright birdsong and virgin forests...
The SPRING by REECHO in cooperation with PEACOCK AUDIO should be associated with this.
Well, it presents itself already colorful and the sound is also a bit refreshing. Responsible for this are 2 dynamic and one balanced armature driver. The configuration has been somewhat forgotten and would have been expected the other way around. Two or three years ago it was the latest thing with the REVONEXT QT2, YINYOO NY-06, or BQEYZ KB1. But the SPRING has little in common with them in terms of sound, and to be honest, I wouldn't have thought of a dual dynamic driver, but rather of two BA's.


For a good 120 €, the packaging and its contents clearly compete with far more expensive products. I don't really care about this and prefer a simple design and only essential supplements for a lower price, but unpacking the SPRING is really fun.

It is similar to a custom IEM in its construction and is also very small and compact. It is very comfortable to wear and with the included tip selection there are no excuses for not getting a proper fit and seal. It was not enough for spinfits, but 2 pairs of foamtips and 3 different types of silicone tips in different sizes offer a really big choice.
Plus a great 8-core 2-pin cable, which is available in silver and bronze/black.
The whole thing is garnished with a leatherette hardcover case with ample space, cable help and snap hook. CHI-FI heart, what more do you want.

Each SPRING is unique in colour. Mix springlike colours (yellow, blue, green etc.) and you get a colourful composition, which reminds of creative batik shirts or peacock feathers. Pretty and appropriate to the theme, but not for someone who likes it a bit simpler.


It would be silly to write that the SPRING sounds like spring, but the sound still has something refreshing about it. Very clear and rather bright, with a solid bass foundation and large stage.

With two dynamic drivers, which probably take care of the bass and the mids, I would actually have expected a bit more rumbling and more quantity. But this is not so. The bass has a pleasant depth, but without developing a particularly high pressure, is punchy and tight, as well as textured and quick on the move. Rather an untypical dynamic bass, although it does have an appealing dynamic. In addition, it remains very well-behaved in the midrange and the signature looks rather tidy and fresh, decently warm and oppressive. For me, the bass is allowed to bring even more volume and kick and to act even more from the deep, but it does what it's supposed to do and that in an extraordinary quality, on which the SPRING puts more emphasis than on quantity.

The mids are crisp and bring a pleasing energy without ever becoming harsh or unpleasant. I would describe the SPRING as quite balanced, with a slight focus on the upper mids and highs, which makes the SPRING sound quite bright, but without slipping into the unnatural. Voices are brought into the foreground, but without jumping into the face. That's the way I like it. The separation of the instruments is excellent and details can be seen in abundance.

One could easily guess from the signature of the SPRING that the Sibilant will become an issue. No, not at all, the area is elegantly curved without any loss of resolution and playability. But the SPRING can't do without it either. Likewise, it can sometimes get a bit tinny in the high frequencies and cymbals stick out too much, which is sometimes a bit exhausting if you get these frequencies too much on your nose. Here the wheat is quickly separated from the chaff when it comes to recording quality and mixing. Airy, detailed highs, which in rare cases can be too good to be true, and therefore do not act completely fatigue-free.

All in all I prefer a little warmer and softer. However, I like the tight bass and the crispy mids, especially in rock or acoustic tracks. Voices sound very round and natural. A bit more body would be good, but you can't describe the SPRING as thin-skinned.
Remarkable is the stage and separation of the SPRING.


Even though there is of course a lot of marketing in the SPRING, I take the sound of spring away from the SPRING. Not too cold, not too warm, clear and direct and with a "colourful" abundance of details.
I can well imagine that there will be other models that correspond to the seasons and I am curious to see how they will sound, even if I already have a rough idea. Until then, you can enjoy the spring-time... eh SPRING. Really a successful IEM.

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

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

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.
