对于真正的无线降噪耳机,我们或多或少有一些遗憾:无线无线耳机种类繁多,但基本上没有人可以做到内部降噪效果好;市场上有很多降噪耳机,但我想要一款。小耳塞似乎没有那么多选择;有些制造商咬牙切齿,做真正的无线并带来降噪功能,也就是说,没有大品牌。花了1500元,总觉得有些东西不见了。

这种硬核的技术要求仍然取决于索尼大法“技术之家”的黑色技术。

索尼音响在全球市场上宣布推出WF-1000XM3,这是一款真正的无线旗舰耳机,具有主动降噪功能。看看命名。您应该知道它应该看起来像WF-1000X的更新产品(噪声Bean,PingWest之前也已经过评估),但它是一个完整的创新,从第二代“M3”也可以看到命名产品,它实际上标有着名的WH-1000XM3。

当然,理论上它基于索尼是一家技术公司的事实:市场上已有的高通解决方案需要真正的无线降噪耳机。索尼认为,这种解决方案无法满足自身需求,开发了单独的降噪芯片QN1e,并将其插入WF-1000XM3。

我们都知道索尼在WH-1000XM3中应用了降噪芯片QN1。效果非常好。实际上,QN1e可以简单地理解为QN1降噪芯片的低功耗版本,并且为了满足小型真正无线降噪耳机的需求,索尼这款自主研发的降噪芯片已经过重新定制。

至于产品的外观和基本功能,将不再描述PingWest产品(公共号码:wepingwest)。这里主要关注索尼WF-1000XM3的技术升级。

负责产品开发和设计的索尼家庭娱乐和音频产品公司高级总经理盛繁提到,“WF-1000XM3重新开发了整个系统,提升了各项性能。”

而性能主要集中在独立研发的降噪芯片.QN1e基于与QN1相同的技术,它是专门为真无线耳机开发的高清降噪处理器。而凭借其低耗能和高信号处理能力,QN1e将生成高精细反向声波,从而实现消除噪音。盛繁说,得益于QN1e,除了顶级的降噪性能,让高音质和低耗能成为了可能。

QN1e附带了数字模拟转化器和放大器,同时实现了24位数字处理,实现了纯净音质。而为了保证更好的降噪效果,索尼在WF-1000XM3上集成了内外两个降噪传感器,通过双噪声传感器技术来拾取噪音:外侧配置前反馈麦克风可检测外部噪音预测到达耳膜的噪音生成噪音信号,内测配置后反馈麦克风可检测到漏入耳道的噪音并生成消除信号

基于新开发的蓝牙芯片,WF-1000XM3可以同时将声音传递给左右两耳,“左右同时传输,减少了音画不同步的情况。”

WF-1000XM3单次续航6小时,搭配充电盒,支持总计24小时续航,10分钟充电可以实现90分钟播放“。通过精细化的半导体优化处理工程,降低电源电压,优化数据通信带宽,将电量消耗减半“。盛繁说

XXSimilar to the previous products, Sony is equipped with an inductive sensor (the polished part of the earphone) on the left and right sides of the WF-1000XM3. The left click will switch the noise reduction mode. The interesting thing is that pressing the left ear will briefly turn off the noise reduction mode. You hear the voices of others. The right side supports click (play/pause), double click (next song) and triple click (previous song), while taking off/wearing the headset can pause/continue playback.

Why is there no LDAC and higher digital processing power? According to PingWest's internal play, this is because LDAC will make the internal signal structure more complicated. When LDAC is adopted, the power consumption of the headphones is improved, and the connection stability is also affected. Sony insiders mentioned that in order to get better connection stability, this is a compromise.

PingWest has also experienced this product at the Sony Tokyo Osaki headquarters (audio and TV development base). After communicating with many media peers, I got some conclusions: WF-1000XM3 has a very big improvement compared with the previous generation. The noise reduction performance and connection stability are better. The connection stability is slightly weaker than the Apple AirPods, and the sound quality is obviously stronger than AirPods. The noise reduction performance is better than the Bird Track Air+, and the wearing comfort is moderate.

Sony has high expectations for this product, and the WF-1000XM3 will become the representative product of Sony's audio industry. Sony's home entertainment and audio products company, representative director and vice president Matsumoto Yoshimoto mentioned that when developing this product, the goal is to lead the industry's leading noise reduction headphones. "Developing a unique noise reduction processor, the goal is to produce the same noise reduction performance as the WH-1000XM3."

"Only Sony can add so many chips in such a small body." Matsumoto said that it will become a new masterpiece of the Sony audio industry.

xx从索尼上周发布的预订情况来看,这款真正的降噪无线耳机WF-1000XM3似乎非常受欢迎。我们也从索尼获得了消息,在宣布后的一两天内,WF-1000XM3有超过3,000个预订单。这对耳机市场来说是一个非常好的开端。

PingWest的后续工作还将更详细地介绍该产品。
