3.5 毫米立体声TRS（尖端、环形、套筒）插孔已经存在了很长时间。最初的 6.35 毫米版本源自 1800 年代后期，用于电话交换机。
3.5mm 版本出现于 1950 年代，至今仍在广泛使用。这意味着你可以拿一副近四分之三世纪前的耳机，并将它们与 2019 年的智能手机一起使用。
除非您购买了 2019 年的智能手机旗舰之一。这已经很长时间了，但智能手机制造商开始完全放弃古老的耳机插孔。这导致了许多哀号和咬牙切齿，但最终，这个勇敢的小音孔很可能最终成为一段古朴的科技史。
然而，我们还没有到达那里，作为尖端移动技术的勇敢采用者，您突然处于您拥有的 99% 的音频配件不再与您闪亮的新手机兼容的情况。如果您购买了功能完善但需要耳机插孔才能工作的高端耳机，那尤其痛苦。
所以现在怎么办？我们稍后会谈到这个，但首先让我们谈谈为什么谦逊的杰克会走上渡渡鸟的道路。
为什么耳机插孔消失了？(Why Is The Headphone Jack Disappearing?)
智能手机工程师想要摆脱耳机插孔的原因有很多。其中一些对消费者有利，另一些对制造商的底线有利。作为一个整体，它们加起来就是事情将要发生变化的明显迹象。
第一个重要原因当然是耳机插孔在每立方毫米都很重要的设备中占用了相当多的空间。耳机插孔只能完成一项工作，因此从设计的角度来看，这是一种昂贵的牺牲。插孔还限制了手机的薄度，尽管从消费者的角度来看，手机需要多薄是一个悬而未决的问题。
除了令人难以置信的薄度之外，倾倒耳机插孔还可以更轻松地为设备防水。这是一个主要的入口来源，没有人再担心了。这也意味着USB-C或闪电端口（取决于您的忠诚度）现在可以使用已经存在的硬件处理音频任务，无论您是否有插孔。这意味着制造商正在消除冗余的主要来源。
移除千斤顶的论据清单很长，但这些足以突出墙上的文字。因此，如果我们都同意没有千斤顶的未来是不可避免的，那么让我们看看如何使用该程序。
加密狗(Dongles)
是的#DongleLife不再仅限于Apple的粉丝，(Apple)三星 Note 10(Samsung Note 10)和 10+等手机也放弃了耳机插孔。您最好的临时解决方案是购买将 USB-C 或 Lighting 连接器转换为 3.5 毫米TRS插孔的适配器。
如果您购买仅提供插孔的简单适配器(simple adapter)，则在使用时必须放弃有线充电。如果您在汽车中使用手机，这可能会很痛苦，因此请考虑购买一款价格稍贵的加密狗，它既可以为您的设备充电，又可以同时提供传统音频支持。
当您使用它时，您甚至可以选择提供HDMI、USB-A或 SD 卡读卡器的型号。毕竟，浪费所有带宽等待从现代端口被挖掘是一种耻辱。请务必从知名品牌中挑选产品。特别是有一些适当的 USB-C 认证的恶作剧，所以在点击“购买”按钮之前做一些功课是值得的。
购买蓝牙适配器(Buy a Bluetooth Adapter)
事实证明，有一种方法可以继续使用您现有的音频设备并(and )利用现代无线数字音频。只需(Just)购买蓝牙(Bluetooth)音频适配器。
这些设备本质上是蓝牙(Bluetooth)耳机和扬声器的蓝牙(Bluetooth)和音频硬件位。他们有一个 3.5 毫米的插孔，你可以连接任何你喜欢的东西。将您的手机与适配器配对，插入您最喜爱的音频设备并播放一些音乐。
您可以购买插入汽车 12V 插座或USB的适配器。电池供电的模型可以夹在您的衬衫上。这是两全其美的方法，但对于如何处理多余的接线有一点点烦恼。它可能比加密狗更贵，但它适用于任何蓝牙(Bluetooth)音频设备，其中远不止USB -C 或 Lighting 音频设备。
尝试无线耳机(Take The Wireless Headphone Plunge)
如果您没有连接到当前的耳机，那么最好继续并更换为无线蓝牙耳机。虽然您可能认为这些都很贵（图 A 是AirPods），但现在每个价位都有无线耳机。
当然，就音质而言，你得到了你所付出的代价，但蓝牙(Bluetooth)本身已经足够成熟，即使是最便宜的无线耳机也不会比有线同类产品贵多少。
高级选项是投资一些独立的、真正的无线耳机，但几乎每种形式的耳机都以无线形式表示。更好的是，大多数现代无线耳机的电池寿命可以用几天来衡量。得益于蓝牙(Bluetooth)技术的最新低能耗版本。
悲伤的阶段(The Stages Of Grief)
当像卑微的耳机插孔这样坚定的朋友摆脱这个凡人的线圈时，感到失落是可以理解的。感到有点沮丧是可以的，但杰克希望我们所有人继续我们的生活并拥抱变化。
或者，您可以永远使用旧智能手机，但我们真的不推荐它。
Why Most New Phones are Ditching the Headphone Jack
The 3.5mm stereo TRS (tip, ring, slеevе) jaсk has been around for a very long time. The original 6.35mm version hails from the late 1800s where it was used in telephone switchboards.
The 3.5mm version came about in the 1950s and is still widely in use today. This means you could take a pair of headphones from almost three-quarters of a century ago and use them with a smartphone from 2019.
That is unless you’ve bought one of the smartphone flagships of 2019. It’s been a long time coming but smartphone manufacturers are starting to drop the venerable headphone jack entirely. This has lead to much wailing and gnashing of teeth, but eventually the plucky little sound-hole is likely to end up as a quaint bit of tech history.
We aren’t there yet however and as a brave adopter of cutting edge mobile technology, you’re suddenly in a situation where 99% of the audio accessories you own are no longer compatible with your shiny new phone. That’s especially painful if you’ve invested in high-end headphones that are perfectly functional, but need a headphone jack to work.
So what now? We’ll get to that in a moment, but first let’s talk about why the humble jack is going the way of the dodo.
Why Is The Headphone Jack Disappearing?
There are plenty of reasons why a smartphone engineer would like to get rid of the headphone jack. Some of them are good for consumers, others are good for the bottom line of the manufacturer. Taken as a whole, they add up to clear signs that things are going to change.
The first big reason is of course that the headphone jack takes up quite a lot of space in a device where every cubic millimeter counts. The headphone jack only does one job, so it’s an expensive sacrifice from a design point of view. The jack also limits how thin phones can be, although how much thinner phones need to be from a consumer point of view is an open question.
Apart from incredible thinness, dumping the headphone jack makes it easier to waterproof a device. It’s one major source of ingress no one has to worry about anymore. It also means that the USB-C – or lightning port – (depending on your allegiance) can now handle audio duties with hardware that was already there whether you have the jack or not. That means manufacturers are removing a major source of redundancy.
The list of arguments for removing the jack is quite long, but these are enough to highlight that the writing’s on the wall. So if we can all agree that a jack-less future is inevitable, let’s look at how to get with the program.
Dongles
Yes #DongleLife is no longer restricted to fans of Apple, with phones like the Samsung Note 10 and 10+ ditching the headphone jack as well. Your best interim solution is to buy an adapter that converts either your USB-C or Lighting connector to a 3.5mm TRS jack.
If you buy a simple adapter that only provides a jack, you’ll have to forego wired charging while using it. This can be a pain if you’re using the phone in a car, so consider getting one of the slightly more expensive dongles that can both charge your device and provide legacy audio support at the same time.
While you’re at it, you may even opt for a model that provides HDMI, USB-A or an SD-card reader. It’s a shame to waste all that bandwidth just waiting to be tapped from modern ports, after all. Just be sure to pick a product from a reputable brand. There have been some shenanigans with proper USB-C certification in particular, so it’s worth doing a bit of homework before clicking the “buy” button.
Buy a Bluetooth Adapter
It turns out that there’s a way to keep using your existing audio equipment and take advantage of modern wireless digital audio. Just buy a Bluetooth audio adapter.
These devices are essentially the Bluetooth and audio hardware bit of Bluetooth headphones and speakers. They have a 3.5mm jack to which you can connect whatever you like. Pair your phone with the adapter, plug in your favorite audio device and jam out to some tunes.
You can buy adapters that plug into your car’s 12V socket or USB. Battery-powered models can be clipped to your shirt. It’s the best-of-both-worlds approach with the minor annoyance of what to do with the excess wiring. It may be more expensive than a dongle, but it works with any Bluetooth audio device, of which there are far more than USB-C or Lighting audio devices.
Take The Wireless Headphone Plunge
If you aren’t attached to a current set of headphones, then it might be well to move on and change to wireless Bluetooth headphones. While you may think that these are all expensive (exhibit A being the AirPods) there are now wireless headphones at every price point.
Of course, you get what you pay for in terms of sound quality, but Bluetooth itself is mature enough that even the cheapest wireless cans aren’t much more expensive than their wired peers.
The premium option is to invest in some independent, true wireless buds, but just about every form of headphone is represented in wireless form. Even better, the battery life on most modern wireless headphones can be measured in days. Thanks to the latest low-energy revision of Bluetooth technology.
The Stages Of Grief
It’s understandable to feel a sense of loss when such a stalwart friend as the humble headphone jack shuffles off this mortal coil. It’s OK to feel a little bummed, but the jack would want us all to move on with our lives and embrace change.
Alternatively, you could hold on to your old smartphone forever, but we really wouldn’t recommend it.
