Driven with a pair of ⌀10 mm titanium-coated moving-coil drivers, t-JAYS is made for accurate sound reproduction and maximum comfort, according to the Swedish manufacturer.
And on top of that, in collaboration with Dirac, the company well-known for their custom sound optimization, JAYS come up with Curves specifically designed for t-JAYS models. While Dirac's DSP technology works most of the time, it may not do the job as well for some applications.
CON: Overly-bass oriented sound signature, an audible peak at 6 kHz, and short bandwidth.
ON SECOND THOUGHT #4: Dirac's Curves resolves two major issues with this IEM: First, the level of low-mid bass is lessend by 10 dB. Second, the audible peak at 6 kHz is effectively suppressed. For the price of $2.99, I think the app does exactly what it's supposed to do.
