Blitzwolf has proven in the past that they are able to produce good and inexpensive in-ears, whether as hybrids, like the BW-VOX1, or the dual driver BW-ES2.
Of course, Blitzwolf is also following the trend and so they now have some True Wireless In-Ears on offer. For testing I have here the BW-FYE3, which is based on a single-dynamic 6mm driver. It is also the first of its kind that I review.


The BW-FYE3 is not only a True Wireless In-Ear, it also uses Touch, which is a bit unusual in the beginning, because you don't get any haptic feedback anymore if you want to "press" or stop a song. The control is done directly at the in-ear, which is surprisingly compact. On the left side you can jump back a song, on the right side it goes forward. You just have to put your finger a little longer on the earpiece until the next song is played. If you only press briefly, the music stops. This way you can also accept calls that are of good quality.

The wearing comfort is excellent, even though the in-ear is simply stuck in the ear, without silicone hooks or other safety devices. Even with fast movements it does not fall out, which is also made possible by the comparatively long nozzle.
It can also be worn in single mode, for example when driving a car, or in stereo mode when on the move.

It is directly recognized whether only one is taken out of the box where the in-ears are stored for loading, or both. They synchronize automatically with each other depending on the option selected.

The isolation is also without complaint, hardly anything penetrates inwards during music reproduction, but also not outwards.

But in any case the playing time still has room to improve. The volume is also very important here, but 3-4 hours is not the measure of all things. But if you have the charging box with you, which also has a powerful battery, you can use this setup for up to 40 hours without having a cable in your hand, according to the manufacturer.
The charging box can also be used as a charging station for mobile phones due to the USB output.


The sound is refreshingly good for a Bluetooth in-ear. Still quite bass accentuated, but the midrange and treble are more clearly in the foreground than I was used to from other Bluetooth in-ears.

The bass is powerful, but positively meant. It has real punch and is especially fun with electro, because you can not only hear it, but also feel it. He also has a very good range. Although he pushes into the mid-range, it's not as strong as with the TENNMAK BT608, for example, and it doesn't carry so much weight in terms of sound either, because it's clean and only rarely tends to boom. But there must also be a lot of bass in the song for this. With the help of the punch of the bass, every running unit or fitness exercise is twice as much fun.

The mids are slightly reduced, but they manage to assert themselves against the bass. They are clear and have a pleasant three-dimensionality. In addition they have no peaks, nor do they sound unnaturally discoloured by the bass. Of course they don't live up to audiophile standards, but they give a good performance and underline the fun character of the BW-FYE3, as they don't hide, but rather sound cheerfully in the upper range, which makes the listening experience more lively.

Unfortunately, we come to a small sticking point with the highs. I can't tell if it's just my pair, or if it's a general problem with the product, but they clink in the upper highs even at slightly increased volume. This isn't really noticeable with electro or pop, but it's already very noticeable with rock, since cymbals and hi-hats sound distorted, as if the driver simply can't handle it. However, this surprisingly varies from player to player. With my LG G6+ this is minimal at best, but clearly audible with my Lenovo laptop. Now the question arises whether this is due to the Bluetooth connection or something else. Of course, this doesn't make it very easy to rate the highs clearly, if they are so strongly dependent on the medium and that's a shame, because otherwise I can get a lot out of the sound. Besides, the highs are clear and rich in detail, at least in the lower range, since in the upper range, due to the mentioned problem, one cannot always speak of a clean sound reproduction. A slight emphasis on the sibilants can also be heard.

The stage is average and wider than deep, but I think that this is not 100% important for the BW-FYE3 area of application, but a nice side feature.
The separation, on the other hand, works quite well, even if there are sometimes overlaps, especially with weaker material.


The clinking in the upper highs is already a small KO criterion for my listening habits as far as genres are concerned. If you prefer EDM, electro or pop and you're not a fan of high volume, or if you're using these In-Ears via a playback medium, which is good for the BW-FYE3, you can really be happy here. The sound is rock solid, i.e. good and the wearing comfort and the innovative handling are successful. If my model is a flash in the pan, you' re holding a really good True Wireless In-Ear in your hands with the BW-FYE3, which is recommended for everyday use and sports.



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!

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.
