First-Look Review of the Bose Noise Cancelling Headphones 700

好的耳机的功能超出了以往。几年前，所有人从耳机中期望的所有人都是相当不错的声音质量。但是如今，人们正在寻找取消降噪功能，无线连接，语音助手支持以及许多类似功能。这确实使选择比以前更加困难，但这也意味着您最终可以使用耳机，这些耳机更加自定义您的个人需求。

Bose降噪耳机700

您可能会或可能不知道这一点，但是Bose实际上是首次将积极的降噪技术带入市场的品牌。从那时起，许多通用品牌就开始发布自己的ANC版本。但是，Bose的ANC仍然被广泛认为是您目前可以获得的最好的ANC。这几乎也是您要考虑的独立ANC唯一要考虑的品牌，您可以在没有音乐的情况下使用噪音消除。

Maybe in a few years’ other brands will catch up. But then again, maybe not. Because Bose seems dedicated to continuing to develop their ANC technologies even further. You can really see that clearly in the contrast between the 700 series and Bose’s former flagship ANC model, the QC35. The700系列are basically meant to be a replacement for the QC35, and as such, they’re basically a linear improvement over them.

Design & Layout

As such, these headphones were designed to outperform or marginally outperform previous generations of ANC technology, almost every way. And Bose has mostly done that by introducing a greater range of granularity to their ANC control. You can personalize your environmental awareness by moving between a grand total of 11 different noise cancelling settings. In fact, the 700 series have almost four times as many noise cancellation levels as the headphones which came before it.

但是，不仅仅是ANC正在改善。Bose噪音取消耳机700使用触摸控件而不是传统的模拟控制。另一个较小的区别是，700系列与Bose Music App连接，这实际上是与许多前几代Bose产品使用的Bose Connect应用程序不同的应用程序。

这种差异似乎很小，因为两个应用程序都可以做相同的事情，但是Bose Music应用程序实际上可以为您做更多的事情。这包括用作交互式均衡器，并使您能够创建许多预设的声音配置文件。从那里，您可以使用该应用程序从任何智能手机或平板电脑中移动。

但是，您再次不想意外下载错误的应用程序。不幸的是，这样做更容易，因为Bose有多个，而且它们的命名类似。抛开该应用程序，可能值得注意的是，700系列有两个品种：经典的黑色和明亮的金属银。黑色对有点柔和而普通，而银对有点科幻和未来派。

Comfort & Portability

耳朵耳机可提供您可以从耳机获得的最佳舒适感。由于实际上没有压力，因此可以舒适地戴上这些耳机八个小时或更长时间，而不必担心会感到不适。此外，耳杯是用漂亮的布料样材料制成的，肯定会在持续使用的情况下可以很好地保持。

耳机like this do have one small issue, and that’s they tend to accumulate heat. It’s really not much of a problem unless you’re already in an environment that’s warm. Because then, these headphones aren’t all that different from throwing some ear-warmers on in the summertime. But provided you’re not trying to listen to them in the middle of the desert, you really shouldn’t find heat becoming a prominent issue.

设计了某些类型的耳机，因此您可以将其弯曲一半。这确实没有太大的舒适性，但是保持耳机功能正常和便携是很好的。关于可调节性，您会发现不锈钢头带可以防止这些耳机以这种方式弯曲。但是使用钢也意味着这些耳机使用的一种移动设备上的一个非常坚固的结构。换句话说，智能设计。

无线连接

700系列使用蓝牙5进行无线连接。这是蓝牙的最新版本，但实际上您不需要过度评估此标准。因为与真正的无线耳塞不同，诸如Bose降噪耳机之类的外耳耳机700不需要与其他同步设备同时播放。

As such, basically any pair of headphones that carries Bluetooth 5 should be able to offer you some pretty stable connectivity. That’s certainly the case here. You don’t get any big benefits with your wireless connectivity range, either. You’ll still want to keep to the typical 30-50ft that you can expect from even most entry-level headphones. But that’s pretty much the only way in which the 700 series don’t grossly exceed expectations in the wireless category.

电池寿命

How long does the battery last? Well, that really depends on a number of different factors. Clearly, if you crank your volume to the max, you’ll end up with a shorter battery lifespan. The same is true of the ANC. If you decide you’re always going to use the ANC, you’ll see a shorter battery lifespan. There’s actually not a gigantic difference in battery consumption between using the first level of ANC and the 11th level of ANC.

But there is a slight difference, and it can matter if you’re trying to squeeze out as much battery life as possible. Another thing that can actually help extend the battery lifespan a tad is taking calls. Calls typically burn through less power than music. With all that said, Bose estimates that you can anticipate around 20 hours of battery performance from the 700 series.

If you’ve got your music cranked all the way up, and you’re always taking advantage of the ANC, then you will find your battery lifespan is probably closer to the 15-hour mark. If you call someone and are on the line for a couple of hours, you might actually end up getting a tad more than 20-hours from your headphones. In all cases, pretty reasonable.

Audio Quality

有几种使音频设备听起来不错的方法。一种方法是使用更好的建筑材料，或使用物理工程来通过调整来创造不同的声音。另一种方法是欺骗耳朵，以为它听不到的东西不是。第二种方法是Bose总是如何完成音频。

尤其是，Bose在带出深厚而光滑的低音线方面做得很好。即使发耳耳机已经擅长重现低音，但Bose确实比其他品牌更进一步。当然，这些耳机不会试图在每种音调上明确说明。取而代之的是，一切听起来有些打磨并平滑。这种声音签名非常典型。

他们的产品背后的硬件通常并不令人印象深刻。但是，这种看似普通的声音硬件由某种最先进的声音技术提供动力，以帮助使其听起来更好，而不仅仅是ANC。例如，值得指出的是，Bose具有一些增强的现实功能，旨在帮助使他们的音频体验既具有沉浸式。

但实际上,非国大的一半以上s these headphones special. When you turn off the ANC, these headphones start to sound much more like almost any other pair of cans. But the ANC really lets you focus on the music, and because you can fine-tune the ANC to be stronger or weaker depending on your needs, you’re never forced to be out of touch with your environment.

不幸的是，如此依赖ANC使这些耳机听起来最好，这意味着您最终会获得16至17小时的电池寿命，而且通常会经常获得。但是，对于那些真正希望能够获得最好的声音阻碍的人来说，拥有最好的ANC是值得的。

Other Considerations

如果您曾经仔细查看过亚马逊回声或Google Assistant设备，那么您可能已经注意到它们是用一个以上的麦克风构建的。实际上，首选数字似乎是四个。因为在几个主题中有几个麦克风使您的语音助手能够更好地将您的声音与背景中的环境声音区分开。您周围的声音需要更长的时间才能到达不同的麦克风，因此可以收集更大程度的清晰度。

骨噪声取消耳机700是用本机Alexa支撑制成的。他们通过四个麦克风系统实现了这一目标，该系统专门为帮助您的噪音隔离了环境中的噪音。可以通过按钮点击或使用唤醒字访问Alexa。同样，对Google Assistant也有支持，可以使用一个按钮打电话。

这些麦克风还有助于获得更清晰的电话。因此，您可以公平地将这些耳机描述为提供业务质量呼叫清晰度，或者至少可以像您在任何当前一代无线技术中所期望的原始性。

In addition to the headphones, Bose Noise Cancelling Headphones 700 includes a USB charging cable, an audio cable, and a carrying case. The carrying case is a sturdy but soft-shelled zip-case. It’s lightly water resistant, and a good way to help store away your headphones during transit.

谁应该选择Bose降噪耳机700？

Bose耳机并不适合所有人。但是，如果您对降噪感兴趣，那么这非常接近您可以做的最好的事情。从技术上讲，对于最好的降噪，您可以动手开启，您需要像飞行员的耳机之类的东西。因为在大多数情况下，这些耳机在头部侧面使用一些夹紧力来帮助提供被动的噪声保护。

But most people don’t want their headphones squeezing them in that fashion. And theBose降噪耳机700不要牢固地挤压您的耳朵，因为它们提供的噪​​声几乎完全是ANC的结果。因此，这些耳机会产生降噪，它们提供舒适感，并提供郊区语音助手的支持。对于那些希望自己的耳机做得不仅仅是听起来不错的人来说，700将值得一试。
