Yamaha launches new wireless headphones (Bluetooth connection), the high-end YH-E700A ($349). They are large headphones, covering the ears, and have 35 hours of autonomy. But the highlight is their noise cancellation system and, above all, that the headphones measure the sound inside (in the ears) and adapt to ensure optimal listening. It’s the ultimate after its immersive 3D sound for home theater systems.
The Yamaha YH-E700A are “over-ear” or circumaural headphones whose cups, closed on the outside, cover the entire ear. They weigh 325 grams and use 40-millimeter-diameter dynamic in-ear speakers. For convenient and safe storage in the original case, they can be folded by rotating them to reduce their size. They are available now in white, black and pink.
As for connectivity, wireless connectivity is Bluetooth 5.0 and supports the most advanced profiles, and sound codecs SBC, AAC, and the highest quality aptX. They also have a wired connection (the highest quality HiRes) and with it we can use its noise cancellation system or sound control, consuming less energy. Anyway, with Bluetooth and the system active, Yamaha announces 35 hours of use after charging, at least. Charging (USB-C connection) takes 3.5 hours to complete.
Of course, it is compatible with voice assistants Siri and Google Assistant, being able to activate them through the touch control button that is integrated. And it also allows the use of hands-free calls, improving the quality of communication.
Noise Cancellation and Better Sound
The new Yamaha headphones are enclosed in a way that already offers some ambient noise isolation. But so that ambient noise affects the user as little as possible, they also have a noise cancellation system: Yamaha’s noise cancellation technology does not interfere with the sound source. Unlike other systems, which can cause low-frequency signals from the music to be lost, Yamaha’s Advanced ANC technology suppresses ambient noise without any processing of the music signal. In-ear microphones, built into the headphones, are designed to listen to, analyze and separate the music from the background noise, isolating both with a new and unique algorithm.
These same microphones are responsible for improving listening in real-time. The size and shape of the head and ears greatly influence how each person interprets the sound coming from headphones. An issue that Yamaha has taken into account when developing this model, including a listening optimizer in it: the internal microphone measures every 20 seconds, analyzes the sealing (possible air leaks from the ears) according to the specific shape of the pinna and the external ear canal of each user, and offer an optimized sound reproduction in real-time correcting the difference between the source and the listening condition. It is a customized sound for each listener.
An added function enabled by this technology helps prevent long-term damage from excessively high volume. Yamaha calls it “Listening Care” and intelligently optimizes audio frequencies in balance with volume. Depending on the music content, instead of needing to alter the volume, Listening Care adapts it in real-time based on data collected from the last 5 seconds. It performs adaptive correction using a 4-band equalizer based on the average volume level. In addition, for a more natural effect, correction parameters are applied slowly over time, resulting in a personalized listening experience based on the music and its environment.
