Questions about this item

Does the Studio-Pro-C come with a detachable microphone and a 3.5 mm audio cable, or must they be purchased separately?

The headphones include an extendable detachable microphone and a 3.5 mm audio cable for wired use; nothing extra is required.

The specs list both 30-hour and 110-hour playtime figures — which one should I expect?

The manufacturer highlights quote 30 hours of Bluetooth playtime, while the supplier data sheet states up to 110 hours; real-world wireless use will be closer to the 30-hour mark.

With a 103 dB/mW sensitivity and 32 Ω impedance, how loud will these get from a phone?

The 103 dB/mW sensitivity and 32 Ω impedance mean a typical smartphone can drive them to high volume levels without an external amplifier.
