Comfort
DISCLAIMER: Comfort is extremely subjective as every ear and preferred usage scenario is different, but we try to convey this element as best as is possible to give you as much of an insight into it as we can.
There are a few elements that make the Tesoro Tuned In-Ear Pro unique - the housing's surface, its slightly longer housings due to their embedded magnets, and the way the cable exit is shaped. Thus, the question around comfort arises. Thanks to the well-fitting tips and light weight, but also due to the fact that the way the flat cable exits the enclosure, you do not feel any additional downward force when wearing them. Thanks to the angled tip of the housing that is shaped like a cone, you will not feel any discomfort when pushing it into your ear.
The things you will have to get used to, as it is different than with other in-ears, are the slightly longer housing and its flat cable. Especially when wearing a head garment, that size results in a bit more pressure than if the casing were shaped to fit your ear in a more natural fashion.
The Tesoro Tuned In-Ear Pro comes with "9.2 mm gaming-class, dynamic drivers for optimal sound output". Lovingly slicing away at the marketing fluff, we are left with the 9.2 mm dynamic drivers - something that can be considered quite mainstream.
The drivers offer a frequency response of 20 Hz - 20 kHz, which is the expected default value as that covers the extent of most people's hearing capabilities. On top of that, Tesoro mentions another important specification: impedance. The Tuned In-Ear Pro offers 16 ohms, which is, once again, quite mainstream. A low value means that the drivers do not require a lot of power to develop high volume. While this is good as it makes such devices a viable option for a wider range of portable products, these devices are also more susceptible to the so-called "blowout" if you were to plug them into an amp, for example. A high value may also mean that some devices are unable to deliver enough power to push high volume levels, but those devices are more suited for personal amplifiers or stationary audio devices.
That said, most mainstream products offer both 20 Hz - 20 kHz and 16 ohms, so the Tuned In-Ear Pro offers exactly what you would expect it for its price segment.
In terms of sound, the pair continues to offer a well-rounded soundscape. Don't expect any mind-blowing depth with them, but they are quite balanced. The bass is adequate enough and the highs are pronounced well, and the mids are not drowned out in the process.
