In the MP3 era, South Korea has three major player brands, Samsung, aliwa and Cowon. Samsung now focuses on mobile communication devices and adds the technology accumulation in the MP3 era to the mobile terminal; Alihe pushed Astell & Kern to build a "hifi consumption upgrade", while Cowon eodi still insisted on making audio products, including plenue series portable players, flagship PS, sub flagship P1 and P2, mid-range positioning PM and PM2 and low-end entry PD, covering the main price range of 1000 yuan to 10000 yuan.In addition to portable players, Cowon has also launched coil iron hybrid headphones Eh2, 4-moving iron plexe X40 and other products. Today, when the true wireless headset represents the R & D strength of the headset brand, Cowon also timely launched the first true wireless headset CF2 in the brand's 20-year history, with a market price of 699 yuan.Selfie inherits Cowon
The overall weight of Cowon CF2 (with storage box) is only 41g. There is almost no sense of load during carrying and wearing. The cavity adopts a more reasonable integrated design. Both sides of the cavity are equipped with microphones, which have the functions of noise reduction and echo cancellation, providing a clear and low-noise call effect.According to the official introduction, the cavity adopts petal type structure and platinum as the main color of the cavity. The combination of platinum gold and black brings a certain high texture to the vision. The petal type structure on the outside of the cavity surrounds a circle of light strips, which will feed back the power when put into the storage box. Cowon CF2 is unified with the past product style in the overall design.Physical keys are set in the earphone cavities on both sides to realize the functions of pairing, music pause and answering the phone. After one pairing, the CF2 can be automatically paired with the previous equipment the next time it is taken out of the storage box, so as to reduce the redundant operation of repeated paired equipment.
Due to the integrated structure design, the wearing process is simple and close to the auricle. Separate Bluetooth pairing can be carried out in both left and right cavities. When Bluetooth pairing is only carried out on one side of the headset, it enters the single Headset mode and can be used as a Bluetooth communication headset. When the power switch is turned on on on both sides of the headset, it will automatically identify dual channels.Stable and reliable wireless connectivityCowon CF2 adopts Bluetooth 5.0 protocol with higher wireless transmission rate, lower energy consumption and wider transmission range, and is equipped with airoha acoustic chip. The chip is designed to optimize small Bluetooth headset. The ceramic antenna has strong anti-interference ability in reading data in close range, and provides IPx4 waterproof grade and daily sweat and rain splash prevention.
Compared with most real wireless earphones, the size of the charging storage box is smaller, and the magnetic absorption method is used to store and charge. Cowon CF2 can play continuously for 3 hours in binaural mode. The charging storage box can provide continuous playing time (theoretical data) for 15 hours in binaural mode. In practical use, the continuous playing time of 12 hours can be fully met, According to the dosage of 4 hours a day, basically flush the motor once every 3 days, and fully fill it after charging for 1 hour.The most important parameters of true wireless headphones are not audio and battery life. These technologies are very mature. The stability of connection is the index of true wireless headphones that the author attaches most importance to at present. Cowon CF2 is relatively stable in the connection process between IOS devices and Android devices, and signal breakage will occur in some extreme cases, It is a very small probability compared with the stability of Cowon CF2.Cowon CF2 does not provide app to adjust headphones, which poses a challenge to the compatibility of front-end devices. We try to use IOS devices and Android (one plus 6) devices for audition. There is no obvious sound effect difference between the mobile phone products of the two platforms in the actual audition process. Therefore, we take Android devices as the main reference devices as the front-end devices for audition, Audition music styles include pop, electronic, classical, folk, etc.
The sound of the first ear is clean and has a certain sense of space. Unlike most earphones within 1000 yuan, which are mainly popular and bass gain, the sound tends to be more inclined to the performance of intermediate frequency and human voice. Especially in the style of folk music, the level sense of human voice and musical instruments is clear and the sense of space is clean; The performance of electronic drum of electronic music is also satisfactory, which brings a certain contrast to the overall musicality. The comfortable and firm wearing method is also suitable for wearing in sports. Cowon CF2 recommended music types: pop, folk, electronic.
Stable Bluetooth connection, embedded ceramic antenna, actual continuous playing for more than 12 hours, flexible single / binaural mode, lightweight volume and weight, these elements are combined for only 699 yuan. Looking at the price of the real wireless headset product CF2 of the mainstream audio brand, it is very grounded, which also brings substantive challenges to the real wireless headset with a price of more than 1000 yuan. With good sound quality and flexible life scene applications, music lovers, mobile game lovers or non-stop phone staff can easily use real wireless headphones of orthodox audio brands, which is the greatest significance for Cowon CF2 to enter the market.
