Chinese maker released the three-unit ring iron headset on January 18, 2021, priced at 2580 yuan (397.69 USD). Since this headset does not have a front cavity vent, it is equipped with a unique T-APB air pressure balance earplug sleeve that is used to ensure the air pressure balance in the ear when it is worn.
On March 11, the brand will put this earplug cover on sale separately. The cost of the two pairs is 58 yuan. It is available in three sizes of large, medium and small. Each pair includes two models of high-frequency enhancement and low-frequency enhancement. The inside of the T-APB earplug sleeve adopts an irregular hexagonal prism design, which can lead to the front and rear spaces.
According to the official, this design helps to reduce the air pressure difference when wearing, relieve ear canal soreness and tympanic membrane fatigue, and at the same time help prevent earphone diaphragm deformation caused by the inability to excrete air pressure during wearing.
By looking at the sound, this design can enhance the sound field, reduce low frequencies, and improve instrumental separation. Angel Jimmy’s three-unit ring iron earphones are designed with a compact metal shell, equipped with MMCX interchangeable cable interface, and standard silver foil wire. Each model of T-APB earplugs is available in blue, pink, green, and gray.
