Overview
The details behind TANCHJIM REVO.
HiFi Sound Dynamic Sound Optimization Secure and Comfortable Fit
TANCHJIM REVO is an open ear wireless HiFi earphone designed for listeners who want high quality sound without losing awareness of their surroundings. Combining an ergonomic open ear design, a large 18 × 11mm dynamic driver, Bluetooth 6.0 with LDAC, and adaptive sound optimization, REVO delivers an immersive yet natural listening experience for everyday use.
Open Ear Listening
Drawing on data from more than 3,000 ear models, REVO is designed to conform naturally to the contours of the ear. The ergonomic structure remains secure during commuting, workouts, and outdoor activities while keeping the surrounding environment audible. This open ear design allows you to enjoy music while staying connected to the world around you.
Lightweight Ergonomic Design
The ergonomic liquid silicone ear hooks are flexible and adjustable, allowing them to adapt to different ear shapes while remaining comfortable when worn with glasses. A built in nickel titanium alloy wire provides flexibility, low weight, and corrosion resistance. At approximately 9g per side, REVO is designed for comfortable extended listening.
Large Diaphragm Powerful Dynamics
REVO features an 18 × 11mm racetrack shaped single dynamic driver with an LCP dome and PU surround. The large diaphragm provides the foundation for strong dynamics and a full range presentation while maintaining the lightweight form required for an open ear wireless design.
Optimized Magnetic Circuit
The magnetic circuit is optimized through finite element simulation to expand the magnetic flux region and improve transduction efficiency. Combined with the driver's long excursion design, the optimized magnetic structure helps compensate for the bass limitations commonly associated with open ear earphones, delivering stronger and more solid low frequency performance.
Dynamic Frequency Response Algorithm
The perceived balance of bass and treble can change as listening volume changes. REVO uses a dynamic frequency response algorithm to adapt the sound according to volume level. By adjusting bass and treble response dynamically, the system helps prevent the sound from becoming too thin at low volumes or overly sharp at high volumes.
Directional Sound
REVO uses a directional sound field to focus audio toward the ears while maintaining awareness of the surrounding environment. This approach provides a more concentrated listening experience while preserving the openness that defines the open ear design.
TANCHJIM Signature App Tuning
REVO supports a 9 band PEQ through the TANCHJIM app, allowing users to fine tune the sound according to their preferences. Multiple preset target curves are also available, including JM-1 and HARMAN series curves, allowing different tuning profiles to be selected with a single tap.
One Touch Control
Touch controls can be customized through the app for convenient everyday operation. Users can configure gestures for functions such as track switching, answering or ending calls, activating the voice assistant, and more.
Beamforming HD MEMS Microphone
REVO uses beamforming technology with an HD MEMS microphone to improve directional voice pickup and speech clarity. Whether commuting, cycling, running, or taking everyday calls, the microphone system is designed to provide clearer voice transmission in different environments.
Seamless Switching Between Devices
Simply open the charging case to begin pairing and connection. REVO supports simultaneous connection to two devices, allowing you to switch between devices more conveniently for everyday listening, calls, work, and entertainment.
High Resolution Audio with LDAC
Bluetooth 6.0 provides stable wireless connectivity, fast transmission, and efficient power consumption. REVO also supports LDAC high resolution audio decoding with a maximum bitrate of 990kbps, providing greater wireless audio bandwidth for compatible devices.
IPX5 Splash Resistance
REVO is tested to IPX5 standards for resistance against sweat and light splashes, making it suitable for everyday workouts and active use. Rinsing, submersion, and underwater use are not recommended.
Long Lasting Battery Life
REVO provides approximately 9.5 hours of listening time on a single charge, while the charging case extends total battery life to approximately 29 hours. With approximately 1.1 hours of charging, the earphones can provide up to 9.5 hours of listening.
