Intro

KB EAR sends a Single-Dynamic Driver and a Single-BA Driver into the race to get started with its product list. The latter is scolding F1 and surprises with its unusual design. A Bellsing driver is installed, which should cover the entire frequency range. The F1 doesn't bother at all with a powerful and deep bass to score but focuses on the midrange and voice reproduction and a good resolution high frequency range. This was also to be expected with a single BA driver, especially with this price tag.

Handling

The first thing that stands out is the unusual design. It resembles a pistol and is completely cast out of resin. The F1 is available in an amber transparent version and in black. Unfortunately there is no elevation at the sound openings, which consist of metal, so that not every tip holds on to it and gets stuck also sometimes in the ear. The F1 seems unbreakable at first sight, due to its workmanship and compactness and I can't claim anything to the contrary even after intensive use. In addition, no one should have difficulty using it, which works equally well with the cable down, or over the ear. The comfort leaves nothing to be desired.

The packaging is similar to that of the OPAL, but instead of 3 pairs of silicone tips, we get nine in total and a silver-coated copper cable. So a scoop has already been put on it.

The F1's isolation is excellent. If the seat is correct, neither anything penetrates to the outside nor to the inside, which requires special care in road traffic.

Sound

You should be aware that you can't expect an exceptional bass, but it plays surprisingly low and very clean. However, you can also force it to its knees at higher volumes, making it overdrive and inaudible. If you don't overdo it, you will get a defined bass, which acts primarily in the mid bass but still gives you an idea of the sub range. Of course I wish for more punch and more base, especially on drums, or bass guitars, but I can also get a lot out of this lightness and precision. The F1 is less suitable for hip-hop or electro.

The mids are the strengths of the F1, voices are reproduced cleanly and naturally. Seldom can a sibilant slip through, or at higher volume it can be a bit unpleasant, but this is a rare side effect. The mids are clear and flat, but without getting boring. In general, one can speak here of a rather balanced, flat signature, which pushes the mids a bit and drops rapidly in the high frequency range after 10 kHz. This takes some time to get used to if you come from a clear V-signature, but then you quickly recognize the potential of the mids.

Despite the fast drop after 10 kHz, the highs still have a lot to offer in the upper range, and subjectively one would attest them an even greater expansion. They look airy and light, but occasionally tend to have unpleasant peaks. The level of detail is really high for the single BA driver and it's fun to discover the smallest details in the music. However, especially in the high frequency range it sometimes sounds a bit too metallic (cymbals).

In terms of space, the F1 also does a lot right, even if no concert hall is to be expected here. Nevertheless, instruments are well separated and voices are pleasantly intimate and natural. Compared to the dynamic driver, however, the F1 lacks some dynamics and is more suitable for analytical listening, especially when it comes to mids and highs.

Outro

What F1 and OPAL have in common is their quite bright tuning. But the F1 sounds much rounder and more musical than the OPAL. Here the tuning of the single BA driver is right and fans of analytical, quiet listening will get their money's worth. The F1 is a cheap, but technically well done entry-level single BA. It impresses with its clean and clear presentation of the musical content, but also does not completely neglect the low frequency range, which might have been expected. But you should always keep an eye on the volume. For me it is a welcome alternative in the Chi-Fi universe because of its sound characteristics, but also because of its design, in order to treat the ears to other impressions.

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.
