The main purpose of supporting aptx coding is to improve the sound quality of Bluetooth headset and reduce the delay, which is the unique technology of Qualcomm chip and the most efficient coding at present. Aptx coding delay is less than 80ms, and lip-synching can be realized when watching TV; The delay of aac coding is about 120ms, and the delay of sbc is close to 300ms, which is more than three times that of aptx. When chasing a drama, the first word can only be heard when the third word is spoken on TV, and the delay is higher when playing games. Don't even think about listening to your steps when eating chicken.
The prince of the shell also has a long battery life. One-sided headphones can be fully charged for 6 hours, and the battery in the charging bin can support the headphones to be fully charged for three times. The total battery life of 24 hours can already meet the daily commute of one week.
In terms of sound quality improvement, the bio-fiber diaphragm used by vivo TWS and Shell Prince has played a great role in improving sound quality. Compared with the general diaphragm, this kind of diaphragm is thinner and thinner, but its surface tension is three times larger. It has the advantages of small mass and strong rigidity, and it performs better in audio transients and details, that is, the cost is higher.
The configuration and sound quality of Shell Prince is the first echelon in 500 yuan. Although it may exceed your budget, it is very cost-effective. In addition to supporting aptx, Prince Shell uses Qualcomm's chip; Headphones are touch-sensitive and can wake up voice assistants; A digital electric quantity display screen is built in the charging bin; IPX5 is waterproof; Charging is the interface of type-C, so it is better to increase the budget and buy a headset with better configuration and more comfortable use.
