HP-P100BT product features

(1)Completely wireless earphones that allow you to enjoy the game to the fullest

・Equipped with a "low delay mode" with a delay of about 40 ms to suppress sound lag

HP-P100BT is equipped with "low latency mode" which is most suitable for game play. When playing games such as FPS (first-person shooter games) using wireless earphones, the synchronization between the video on the connected device and the audio in the earphones greatly affects the reaction speed of the player, and is an important factor that determines the outcome of the match. It's one of The amount of audio delay in the "low delay mode" of this product is about 40 ms (0.04 seconds)*1, which is the highest class in the industry, and if the video is 60 frames per second, the delay is only about 3 frames. It's extremely small.

Normally, when playing audio with Bluetooth earphones, etc., the transmitter (smartphone, etc.) and receiver (earphones, etc.) send and receive audio data multiple times, and check whether the transmission and reception were performed correctly. is determined, and processing is performed to play back the audio without interruption. In general, as this processing time increases, "sound lag" occurs, in which the audio is delayed more than the video.

The "low delay mode" of this product has realized the suppression of "sound lag" by optimizing the number of times voice data is sent and received. Furthermore, this function does not depend on the type of communication codec used with the connected device, so you can experience low audio delay regardless of the device. *2

・Optimal tuning for gameplay

The HP-P100BT not only allows you to enjoy listening to high-quality music, but also makes use of the powerful sound quality of the Φ10mm large-diameter dynamic driver, tuned for a delicate and rich sound that is ideal for game play.

While playing games, gunshots and footsteps can be accurately captured without impairing the directivity of the sound, and voice chat is clear. Assist your victory with a realistic sound.

・Long-lasting comfort even during long game play with a fit that sticks to your ears

The HP-P100BT earphone housing is designed with an organic shape that fits various ear shapes. It does not put an extra burden on your ears, and greatly reduces pain and discomfort while wearing. You can comfortably use it for long game play and music listening, and you can enjoy a high sense of immersion in the game.

(2) Equipped with ultra-high performance "hybrid noise canceling mode"

Noise canceling is a function that makes it difficult to hear by reproducing the noise that is collected and analyzed by the microphone inside the earphone in the opposite phase.

HP-P100BT uses a hybrid system with two microphones on each side for sound collection. A feed-forward microphone placed outward on the earphone housing collects ambient sounds and suppresses noise. In addition, a feedback microphone placed closer to the eardrum collects the sound output from the earphone, analyzes the error signal, and eliminates noise more strictly. Compared to a general feedforward microphone alone, it exhibits a higher noise suppression effect, allowing you to comfortably enjoy playing games and listening to music on trains and buses. The suppression effect is especially focused on the band around 60Hz, and it is highly effective against the vibration noise of trains and the cabin noise of airplanes.

In addition, the noise canceling function is useful when you want to concentrate on work or work while listening to music. Also, if you turn on the function without playing music, you can use it as a digital earplug.

In addition, it also has an ambient sound mode (external sound capture function), so you can instantly listen to conversations and station announcements without removing the earphones while playing games or listening to music.
