Appearance Design & Accessories

The accessories of iKF King are quite rich. In addition to the headset, there is a storage bag, manual, external microphone, Type-C charging cable, AUX audio cable and adapter.

The iKF King earmuffs are made of protein leather + zero pressure memory foam design. The material of the earmuffs is quite comfortable to the touch, and it will not press your ears when you wear it on your head. The skin-friendly and soft memory foam still feels comfortable even after wearing it for a long time.

iKF King adopts the design of telescopic arm + rotating head cover, which can be adjusted according to the head shape of different users to suit their own wearing style. The head beam of iKF King is designed with metal material, so it can adjust the angle without fear of violence.

The left earcup of the headphone is designed with some function buttons and interfaces. Such as volume kbutton, switch button, ANC button, microphone jacks and audio jacks. When using headphones, some functions and connection operations are implemented here.

Active Noise Cancellation (ANC)

iKF King headphones have a built-in active noise cancellation system and use hybrid ANC technology with a professional acoustic architecture. The noise cancellation depth of iKF King when the ANC mode is turned on can reach 38db. Whether it is in a noisy environment such as a subway station or a large supermarket, it can effectively shield the surrounding ambient noise.

I have been wearing the iKF King for the past few days to test its noise cancellation performance in different environments. For example, when taking the subway, the ANC mode is turned on, and the sound of the subway and the surrounding environment is almost effectively attenuated. In addition, you can switch to the transparent mode when wearing it, and you don’t have to worry about missing the prompt sound of the subway station when listening to songs.

In general, the active noise cancellation performance of iKF King is not very good, but it is still OK. In the $60 price range, the iKF King is definitely an affordable and cost-effective over-ear bluetooth headphones.

Acoustic Configuration & Sound Quality

iKF King is equipped with a new generation of Bluetooth 5.3 technology, and its connection is faster and more stable than previous generations of chips. iKF King has a built-in 40mm polymer composite diaphragm dynamic driver, which can accurately analyze the sound details of each song in all directions.

Through the actual song audition, I chose this “A Thousand Reasons for Sadness” by Jacky Cheung. When the song is played, every tone of the piano piece in the prelude can be clearly heard, and the bass performance is also strong and powerful. The vocal part is also delicate and real, bringing the singer’s poignant voice into full play.

Game Experience

Officials claim that iKF King can support professional-level game modes. When playing games, the latency rate is as low as 45ms, which is almost a latency range that the human ear cannot perceive. So how does it actually perform in games? I usually play “Game For Peace” a lot, so I will test it with this game.

With the support of the latest generation of Bluetooth 5.3, the latency rate in the game is lower. During my actual game testing, I could clearly identify the opponent’s footsteps and gunshots.

In addition, when speaking with teammates, you can also plug in an external microphone. When the microphone is turned on, the sound quality and sound channel are also clearer and more stable, which greatly improves the game experience.
