I could start this review by calling this product the best IEM for around €40, and I wouldn't be lying, but I want to explain exactly why I think that and why these STA-Ks are hard to beat in their category. The Ear Acoustic Audio STA-Ks are easy to recommend, and once you try them, you'll find it hard to put them down. In fact, you'll use them not only for top-level music listening sessions or for vocal monitoring if you're a singer or musician, but also for gaming, podcast listening, and much more.

First of all, the STA-K are characterized by a truly WOW design, which you will hardly find on such cheap IEMs, but above all at a very low price, we take home a 2×1, or a double driver configuration, and specifically you have a dynamic driver with a 10 mm beryllium-coated diaphragm and a 6 mm dynamic driver.
Basically, one driver will take care of the bass and the other of the other frequencies, for a balanced
tonal range across the entire spectrum. These earphones have a frequency range of 10 Hz to 30.000 Hz with a sensitivity of 110 dB and an impedance of 32 ohms. But let's review the build quality and comfort of this set of earphones. The package includes a user manual, three pairs of silicone tips of different sizes, and the cable, while a carrying case is not included. The cable is inexpensive but made of oxygen-free copper, silver-plated, and is 1,2 m long. It ends with a 3,5 mm jack and 0,78 mm pin. However, there is also a version with a Type-C connection and microphone or a jack and microphone.
The STA-K Silver Angel are very comfortable to wear, being lightweight and with a very ergonomic shape. I haven't noticed any annoying noises coming up the cable, for example when we shake our head while listening to music or when we're listening to music. The earpieces seem to be made of resin with some aluminum inserts, while the front has a diamond texture and a small vent to avoid completely blocking the ear canal. The IEM is neither too big nor too small, adapting to practically every type and shape of ear. There's a small pointed area in the resin cap for a better fit, making the STA-K really stable. As mentioned, they're very comfortable: after hours of use, I didn't feel any pressure.
or discomfort inside the ears, isolating very well from external noise.
But let's get to the point, how they sound. The STA-K Silver Angels, considering their price, sound wonderfully good, a real surprise. If I'm not mistaken, we're talking about a price around 40 euros, and for this amount, they have a V-tuning, an EQ configuration that emphasizes the low and high frequencies, creating a sound rich in nuances but without being too energetic, with frequencies across the entire spectrum well controlled. The highs are not too bright but quite clear in all the musical genres I tested these IEMs with. I'd say that if you are sensitive to treble, these STA-Ks are perfect for you. The high frequencies offer ample detail and clarity while the mids are not overwhelmed by the
mix, especially on very intense tracks. At low frequencies, there's ample rumble that allows for more bass extension and power, without being too loud to be annoying. So you might think these IEMs aren't suitable for genres with generous bass, but you should keep in mind that in general, IEMs aren't meant to pump things up, but to reproduce sounds as naturally as possible.
I'm not a professional singer or musician, but I wanted to test these STA-Ks with video editing and gaming, and I discovered that they are very well suited to these uses. In fact, the realistic sound reproduction of these IEMs allows you to better manage the soundstage and spatiality you seek in certain games or video editing. For example, in gaming, where in some titles it becomes essential to hear footsteps, when approaching enemies are generally reproduced around 250 Hz, everything is reproduced with maximum precision, zero latency, resulting very clear from the sound context, without being overwhelmed by other noises. Is this not enough for cheap earphones?
I didn't just play, also because I'm not a gamer, and so I carried out various audio tests, confirming my positive impression and opinion of this product, which I would define as all-purpose IEM earphones in terms of music, gaming and audio in general.
