WFK's "Bluetooth Earphones-A66" uses the industry's highest class Bluetooth 5.3 + EDR technology, supports "TrueWireless Mirroring" technology that allows the left and right earbuds to communicate independently, and consumes less power than previous models. It provides a more stable connection and high-speed communication, enables clear calls, and greatly improves "sound delay" and "sound dropout". A special new ergonomic design provides greater wearing stability and comfort. 🌟 [Instant connection when you open the lid] Equipped with auto on/off and auto connect functions, once pairing is completed, you can instantly turn on the power and pair automatically just by opening the lid. After use, return the earphones to the charging case and close the lid to turn off the power, making it easy for even beginners to connect. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 🐳 [High-performance ENC noise canceling that invites you to a new world of sound] 🐳 Completely wireless earphones equipped with the acoustic technology cultivated through the development of WFK's Hi-Fi audio equipment. By using a specially designed 11mm large-diameter ultra-wideband dynamic driver unit, we have achieved realistic high-quality sound that is full of immersion. Built-in CVC8.0+ENC noise cancellation (Environment Noise Cancellation) achieves a noise reduction effect of up to 25 dB in the audible range, reducing over 90% of environmental sounds such as city noise, traffic noise, wind noise, etc. This creates a highly immersive and comfortable listening environment whether you are on the go or indoors. You can easily use these headphones in public places without worrying about not hearing any sound. 🌊Reliable Water Resistance: Equipped with drip-proof performance equivalent to IPX7, so you don't have to worry about sudden rain or sweat from exercise, making it ideal for a variety of situations such as running, jogging, hiking, and fitness. (Not compatible with swimming) You can enjoy music comfortably at any time. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 🐳 [Hands-free calling function / up to 60 hours of continuous use] 🐳 A66 wireless earphones are equipped with a "HFP" (Hands-Free Profile) profile and a directional microphone, and high-precision voice pickup that performs advanced audio signal processing. Technology provides high call quality. You can receive incoming call notifications while enjoying music playback, and you can use the wireless earphones for calls, telework, and online classes. You can use only one side, even if either the left or right side is left in the charging case. While charging one, you can enjoy music or make hands-free calls with the other. We have adopted a design that thoroughly reduces power consumption when driving the earphones, achieving 8 hours of continuous playback with just the earphones. It has a built-in 500mAh large capacity and can be used for up to 60 hours of continuous playback when used with a charging case. The charging case has a compact design that allows you to easily take it outside. 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 🐳 [Multi-functional touch operation/Remaining capacity display] 🐳 You can easily perform basic earphone operations with one touch, so you can listen to the song you want to listen to right here. You can operate it in your ear while wearing earphones. (Play/pause/song forward/backward/volume adjustment/call start/end) Supports activation of voice assistant function. You can enjoy music without worrying about tangled wires while training at the gym or jogging. *It has excellent interchangeability and is compatible with most devices such as IOS, Android, Mac, and WINDOWS. Equipped with an LED display, the remaining charge in the charging case is displayed numerically, making it highly visible and easy to understand at a glance. Also. By lighting up the LED light, you can check the charging status of the left and right earphones in 4 stages, eliminating the worry of them running out midway. 🌈 [Compatible with type-C charging] Compatible with type-C, which is currently becoming mainstream. A charging cable is also included, so you can charge it anytime, anywhere! 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 🐳 [Lightweight design/comfortable to wear] 🐳 Despite the powerful bass, the earphones have a compact and lightweight body weighing approximately 6g and the charging case approximately 41g. We have adopted an "ergonomic surface design" that increases the contact surface between the earphone body and the ear. The shape makes it difficult to interfere with the complex unevenness of your ears, making it comfortable to wear for long periods of time. 🌈[Dedicated earpiece included] A lightweight and compact type that uses a "earplug type" that fits well, so you won't get tired even if you wear it for a long time, and you can wear it without worrying about messing up your hairstyle.
