Our Verdict 
These Monsters look the part for sure, but we'd like them to be more of an all-rounder to gain that fifth star
For 
Eyecatching design
serious bottom end grunt
great smoothness
Against 
Lack some grip and definition
Reviewed on

These Monster in-ears feel like a meatier, weightier prospect than some rivals.

The packaging claims that the PROs produce "bass so deep that it sounds like a subwoofer in your ears". We can't say that we've ever wedged a sub down our ear canals, but what we can say is that the Monsters are certainly very generous in the bass department.

Play 50 Cent's In Da Club, and there's real force behind the delivery. The trade-off for all that powerful bass is that they can slightly miss the mark when it comes to grip and definition .

Composure and smoothnessThat said, with potentially shrill and bright tracks, these Monsters are reassuringly rounded. La Roux's self-titled album can sound hard and uncomfortable in the wrong company, but the Monsters really impress with remarkable composure and smoothness.

The Turbine PROs are a very eye-catching design, and their low-end grunt will impress many. The only drawback is that their all-round performance doesn't quite match that of comparable rivals.
