The Tesoro Tuned In-Ear Pro tries hard to stand out, and a lot is done to market it in a way that conveys the fact that it delivers some sort of special audio experience for gamers over its mainstream counterparts. So, let me address that first: Tesoro uses words like "Tuned" and "Pro" in the naming of these in-ears. Both terms make them sound like there is some unique element of engineering involved to give you better audio. The same goes for the "gaming-class" when describing the pretty standard 9.2 mm drivers.
Long story short, there is nothing unique about the soundscape. This in-ear offers the same audio performance as most other in-ears in the $30-$40 price segment, which is not a negative aspect, though I can see how some users could hope for more after having read all that marketing fluff.
That said, the Tuned In-Ear Pro does offer a nice set of functional features that set it apart from other mass market products out there. Starting with the rugged housing and its embedded magnets, you can clip them together around your neck easily - perfect for those who like to route the cable around the back of their neck. In addition, the flat cable essentially eliminates all but the very loose cable mess. All these make the Tuned In-Ear Pro great for the road warrior.
That theme continues when you look at the specifications. With the standard frequency range, mainstream driver size, and low impedance, it is dab smack right where the mass market cites it should be in terms of technical details.
The Tesoro Tuned In-Ear Pro is priced similarly to other in-ears, but adds a few little features to set it apart from the crowd ever so slightly. However, as far as in-ears go, audio trumps extra function or convenience most of the time. So, the Tesoro Tuned In-Ear Pro is a solid in-ear, and the magnetic functionality can make your life easier in some scenarios, but it ultimately does not push the audio envelope as much as needed to really set itself apart from the vast number of choices out there.
