Q&A Section

Q: What type of sound signature does the U12t offer?
A: The U12t delivers a reference-level sound with extended highs, detailed mids, and powerful, clean bass, ideal for critical listening and casual enjoyment alike.

Q: What drivers are used inside the U12t?
A: It features 12 balanced armature drivers, including a tia high driver, one high-mid driver, six mid drivers, and four low drivers for exceptional frequency balance and separation.

Q: What’s the benefit of tia™ technology?
A: tia™ eliminates traditional sound tubes to reduce resonance and distortion, offering clearer, more lifelike sound reproduction with improved high-frequency response.

Q: What are apex™ modules, and what do they do?
A: Apex™ modules relieve inner-ear pressure and provide passive noise isolation, enhancing comfort and soundstage; U12t includes three interchangeable modules: mX, m15, and m20.

Q: Does the U12t sound different depending on the audio source?
A: No. Thanks to LID™ technology, U12t maintains its sound signature regardless of output impedance, offering a consistent experience across devices.

Q: Are different cables included with the U12t?
A: Yes, U12t comes with the Pearl Premium Cable in both 3.5mm single-ended and 4.4mm balanced configurations, offering flexibility and superior signal transfer.

Q: Is the U12t good for long listening sessions?
A: Absolutely. The ergonomic shell design and apex™ pressure relief reduce fatigue, making the U12t ideal for extended use.

Q: What comes in the box with the U12t?
A: You get the U12t IEMs, a carry case, a full tip kit (foam, SpinFit, silicone), two premium cables, apex™ modules (mX, m15, m20), and cleaning accessories.
