原文： It was time to replace my 20+ year old David Clark's, and I was torn between going with the DC ONE X or the Bose A20. I've been a loyal DC customer for a long time, and their products never let me down, plus the DC's are roughly 25% less expensive. But I've also flown with Bose, and they've always i
mpressed me with the amazing Bose noise suppression. In the end, since I needed a pair of headsets, I ended up buying one of each - and so far, I have no regrets about either purchase.
If you're in this position too, I thought I'd offer a comparison of these two terrific products...to me, there's no clear hands down winner here - each headset is good at different things. Indeed, both are amazing in their own right, and the good news is that this means you can't go wrong with either one, especially if you're like me and are upgrading from older technology.
In terms of overall construction quality, I'd give a slight edge to DC. Both are very good and should hold up a long time, but the Bose feel like high-end consumer products, while the DC's feel "professional". Although the Bose are slightly lighter, the DC's are quite a bit more compact with a smaller control pod. The Bose case is larger, but more protective. Both products pair easily with Bluetooth phones/tablets, and I've had no connectivity issues with my iPhone or iPad.
I don't like that both products make it difficult to access the optional features like auto-off and stereo/mono. Granted these tend to be "set and forget" options, but in both products, you need to pop open the battery compartment and remove the batteries to change these settings. Speaking of batteries, I use lithium batteries in my headsets, and both seem to provide better battery life than you might think - at least 50 hours.
In terms of comfort, there's no clear winner. To me, the DC's feel smaller but less secure on my head - in turbulence and with thicker sunglasses on, they sometimes slide around on my head, no matter how I adjust them. The Bose have larger ear cups that tend to feel more secure, although they also tend to make me feel a little sweaty in warm weather. In smooth air, the DC's are more comfortable to me, but I don't like the sense that they might shift on my head if I move too quickly.
As for overall sound quality, both are good, but to my ears, the DC's are slightly clearer with voice communications. I think the better noise suppression in the Bose does interfere slightly with audio legibility, and sometimes I find myself struggling with ATC communications that seem to come through more clearly on the DC. I find the microphones to be a tie - I've never had less than a "loud and clear" response on any com check, and they work equally well with my phone or with the airplane.
Of course, the reason you spend big bucks on a headset like this is for the noise suppression, and here is where the Bose headsets excel. Although the DC's are quite good, the Bose are simply better. Sometimes I'll switch from one or the other in flight, and the difference is immediately obvious. On the other hand, if you didn't have them side by side, you'd probably find either one to be more than good enough - but if you fly in a really loud environment and want the best possible noise suppression, then the Bose is the winner in this regard.
I'm happy to say that both are made in the USA, and both companies have good customer service. DC especially has really impressed me over the years...I once had a ten year old headset repaired (I crushed the cord), and they came back with new ear seals, headband pads and so on - all at zero charge to me.
Bottom line is that I'm happy with the Bose A20's and if you're looking for the best aviation headset that will have maximum noise suppression in a noisy cockpit, then you can't go wrong with the Bose - although in my opinion, they aren't the only game in town.

译文： 是时候替换我用了20多年的David Clark's了，我在DC ONE X和Bose A20之间进徘徊。我一直以来都是忠实的DC客户，他们的产品永远不会让我失望，而DC的价格也便宜了25%。但我也使用过Bose，Bose的噪音抑制效果给我留下深刻的印象。最终，我想我需要一副耳机，我就每种耳机都买了一副，到目前为止，我对这几款产品都没有后悔。
如果你也有这样的想法，我将提供这两种很棒的产品之间的比较。对我来说，两者没有明确的赢家每款头戴式耳机都能很好地解决不同的问题。事实上，两者效果都是令人惊异的，好消息是，这意味着你使用任何一个都不会出毛病，尤其是你像我一样，正在升级旧的版本。
就整体制造质量而言，我给DC略高的评价。两者都很好并且应该将这样的状态长时间保持下去。但Bose感觉就像高端消费品，而DC则让人感觉更“专业”。虽然Bose的重量更轻一点，但DC的控制盘更紧凑一些。Bose的盒子更大，但更有保护作用。这两款产品都很容易与我的蓝牙设备/平板电脑配对，而且与我的iPhone or iPad也没有任何联网问题。这两种产品都很难访问像自动关闭和立体/mono这样的可选功能，我不喜欢。当然，这些都是只需设置一次的一劳永逸的选项，但在这两种产品中，你都需要打开电池盒，取出电池来更改这些设置。说到电池，我在我的耳机里使用锂电池，而且这两种电池似乎都比你想象的中的电池寿命更长至少可以使用50个小时。在舒适方面，没有明显的赢家。对我来说，DC的感觉起来体积更小，但不太安全，在强风中并戴着较厚的太阳眼镜的时候，不管我怎么调整它们，它都会在我的头上滑动。Bose的耳罩更大，虽然让人感觉更安全，但是它们也会让我在温暖的天气里感觉有点出汗。在较平和的空气中，DC对我来说更舒服，但我不喜欢在我移动走动的时候它们可能会在我的头上移动的感觉。
至于整体的音质，两者都很好，但对我来说，DC在通信方面的声音更加清晰。我觉得Bose的噪音抑制会影响音频的清晰度有时，而且我发现有时候自己在ATC的通信中苦苦挣扎，而在DC中的通信却显得更清晰。我甚至觉得在麦克风上，两者打成平手。我在任何的网址上没有少过“响亮而清晰”的回复，而且它们在我的手机或者在飞机上也同样很有效。
当然，你在这样的耳机上花大价钱的就是为了抑制噪音，而这正是Bose耳机的优势所在。虽然DC也不错，但Bose的效果更好。一方面，有时我会在飞行中相互切换，区别就显而易见了。另一方面，如果你没有把它们并排放在一起，你可能会觉得两款都挺好的。但是如果你在一个非常嘈杂的环境中飞行并且想要最好的抑制噪声的效果的话，在这一点上，Bose就是赢家。
我很高兴这两种产品都是美国制造的，而且两家公司都有很好的客户服务。多年来，尤其是DC给我留下了深刻的印象。曾经我修理过一个用了十年的耳机 (我把耳机线压碎了)，他们又给我寄了新的耳罩、耳机头箍，对我来说简直零损失。
最后就是，我对Bose A20很满意。如果你想要在嘈杂的驾驶舱里有最大噪音抑制作用的最好的航空耳机，那么你就不能错过Bose。尽管在我看来，它们并不是唯一的选择。
