A CAT is a kind of cute and spiritual creature, and it will give people an intimate affection whenever it is. Cat ears are sensitive and agile which have the ability to perceive all details. C.E.A. (Cat Ear Audio) wants to use technology to explore all true, accurate, and rich details in the acoustic field. We hope to use this to establish a brand concept, bring our professional audio products to the public, and let more people come into contact with HIFI audio products.

The C.E.A. (Cat Ear Audio) brand was registered in Shenzhen, which is a new sub-brand of ShoonTH.

The founder and director of sound engineering is Mr. Sheng Hongming. He served as senior electrical engineering and electrical automation engineer and project supervisor of China Baowu Iron and Steel Group Co., Ltd. He has good knowledge of electricity, magnetism, physics, industrial engineering design, etc. He is committed to the design and development of wire products for more than ten years, has rich experience in listening and tuning, applied for a number of patented technologies, and has strong research and development strength. He founded Shunshi Audio in 2013 and registered the brand Extraordinary Sound (formerly used) in 2017, created the ShoonTH brand. C.E.A. (Cat Ear Audio) brand was founded in 2019.

The C.E.A.（Cat Ear Audio）brand is positioned in the field of acoustics: design, development, production and sales of high-fidelity headphones, digital HIFI, and digital fashion products. C.E.A. (Cat Ear Audio), with its unique design and development capabilities, creates a new concept of headphones and digital products, just like a cat, mysterious and cute, cold and smart, compatible with sound and design, and let fashion and technology collide.

Cryogenic freezing is a metal processing method. The freezing of the whole machine is to assemble and weld the entire headphone conductor part, then place it in a -196℃environment for static storage, and then warm up to room temperature after a period of time. Repeat this process three times. The time of freezing and warm up is different. The total time is as long as 72 hours.

Metal freezing treatment can effectively change the arrangement of the crystal lattice of the metal itself, and reduce the gap between the crystal lattices to increase the conductivity. The freezing of earphone connectors, wires, coils including earphones and welding points of various parts can be effectively improve the overall sound performance of the earphones.

Burn in earphones is very necessary. Because C.E.A. earphones have undergone a three-stage Cryogenic freezing process, the conductor lattice has changed, so the conductor needs to be energized to regenerate the directionality of electronic conduction, so that you can make the earphones into the best state as soon as possible.

Take out the earphones and plug them into any playback device. Pick a dozen soft but comprehensive music (including more musical instruments and singing), and adjust the volume to 70%—80% of your usual listening habits. Turn on loop playback and let it play continuously for 24 hours to make the earphones to be its best condition.

The tuning style of C.E.A. is to experience the sound of nature.
