JAYSUING U9 Carbon Black earbuds

The JAYSUING U9 are true-wireless in-ear headphones finished in Carbon Black. They connect over Bluetooth 5.4 and ship with a multifunctional touch-screen charging case, three pairs of ear tips and a charging cable. Touch controls on the buds handle playback, calls and mode changes without reaching for a phone. The package is aimed at adults who want a single set for music, calls, exercise and commuting.

ANC with 45 dB reduction

Active noise cancellation emits reverse sound waves to cut environmental noise by up to 45 dB, while ENC processing keeps voice clear during calls. A transparency mode lets outside sound in when awareness is needed. The 14.2 mm bio-carbon fibre dynamic drivers reproduce bass down to 50 Hz and treble up to 5 kHz, and five EQ presets — standard, classic, jazz, rock and pop — adjust the tonal balance. Bluetooth 5.4 improves speed, efficiency and stability over Bluetooth 5.3.

For commuters and active listeners

The IPX7-rated buds survive heavy sweat and rain, making them suitable for running, cycling and gym sessions. Battery life is six hours per charge and the case extends total listening time to 48 hours. Buyers who want on-ear or over-ear comfort, wired connectivity, or a higher water-resistance rating for swimming should look at other form factors.
