尼基塔第三季

USB C型耳机还没起飞,无线是未来

食尚玩家

由于3.5毫米耳机接口占用了太多的空间,苹果开始取消2016年iPhone7的耳机插孔。尽管当时其他手机制造商并未立即跟进,但一年后,他们最终未能抵制取消3.5毫米耳机插孔的潮流。为了弥补3.5毫米耳机孔的不足,一种带有USB C型接口的耳机应运而生。但现在一年多过去了。令我惊讶的是,USB-C音频设备并没有像预期的那样起飞。它们很少出现在刚刚过去的2019年CES上。他们背后的原因是什么?理想是很充实的,现实是很骨架的。在出现带有USB C型接口的耳机之前,制造商使用了USB C型到3.5毫米耳机插孔适配器方案一段时间。但这太麻烦了,一些适配器没有内置的DAC(数模转换器),导致许多兼容性问题。此后,制造商开始陆续推出USB C型接口。头戴式耳机。USB C型耳机有自己的DAC和放大器,可以绕过智能手机的内部部件,使音频信号尽可能长时间处于数字(无损)状态。音质的损失只存在于耳机线上,理论上可以提供更好的音质。事实上,USB C型耳机存在以下问题:一个好的USB C型耳机内置了自己的DAC和放大器组件,而不是使用智能手机内部的组件,因此它通常比相应的3.5毫米耳机更昂贵。通过将耳机分配到USB C音频类型,智能手机可以识别出插入设备是耳机,但根据兼容级别,耳机的某些功能可能无法实现。由于并非所有的USB C型耳机都内置了数模转换器(数字到模拟),这些耳机都不是数字耳机,而且手机还没有广泛支持音频连接模式,因此用户会遇到许多兼容性和识别问题。理论上,USB C型耳机的音质更好,但事实并非如此。著名音频媒体SoundGuys的编辑说,谷歌的像素耳机在音质上与同类价格的耳机不匹配。实际上,音质不是USB C型耳机的主要问题,但最大的问题是兼容性。Nowadays, there are DAC modules in mobile phones, so whether there are DAC modules in headphones or not, that is to say, even if headphones are not digital headphones, they can use DAC modules in mobile phones. However, because the standard of USB Type-C is not yet unified, there are many compatibility problems in the use process. For example, when a foreign media editor tested AiAiAiAi Pipe 2.0 USB Type-C headset, he found that only LG G6 could recognize the headset. Although LG G6 could play music normally, it could not use its microphone when it was used to make phone calls. In addition, the mobile phones notification Center showed that the headset was a mobile power supply, even if it could play music normally. There are many examples of this. Although the USB Type-C bullet headset with one mobile phone is perfect compatible with ones own mobile phone, it can not be used in Pixel 3 XL; the USB Type-C version of Millets own noise reduction headset can support Millet 5, Millet 5S, etc., but it is not compatible with Millet 5C, Red Millet Pro, while Millet 4C and Millet 4S support music and noise reduction functions, but it does not support the functions of call and button. All the above problems are caused by the inconsistency of standards. Generally speaking, there are two incompatible problems with USB Type-C headphones. The first one is that they are not recognized directly and can not be used at all. The second one is that some functions will be missing, such as noise reduction, keying, telephone, etc. If you need to take the risk of incompatibility to buy headphones, Xiaobian believes that this will greatly affect the enthusiasm of users to buy, and this issue is completely not considered in the era of 3.5mm headphones. At present, the status quo of USB Type-C headphones in 2019 is not as good as expected. On the one hand, there are some problems in them. On the other hand, more manufacturers are launching real wireless headphones, and the price of these headphones is becoming more friendly. But at present, wireless headphones still can not meet the needs of many people, including In terms of sound quality and delay, it needs to be further improved. However, the trend of Google search shows that the search volume of "USB Type-C headphones" has steadily increased in 2018. The growing consumer interest should enable more companies to devote themselves to the research and development of USB Type-C headphones, and ultimately solve the compatibility and functional deficiencies of USB Type-C headphones. Wireless is the future of wireless headphones in the past year has made great progress, in addition to Apples thriving IrPods, Huawei, Millet, Samsung and other mobile phone manufacturers have launched their own real wireless headphones, allowing users to have more choices. Other traditional audio giants, such as Bose and JBL, are not idle. True wireless headphones have been launched. Although the price is not close to the people, the performance of sound quality is beyond that of AirPods. Like the transition from wired phone to mobile phone and wired charging to wireless charging, the popularity of wireless headphones is only a matter of time. In fact, at present, wireless headphones are one of the fastest growing branches in the science and technology industry. In the past year, wireless headphones have made great progress in the aspects of endurance, noise reduction, voice control and design. Now, besides a few music enthusiasts and game users, wireless headphones have been able to meet the needs of most ordinary users. Of course, it is undeniable that wireless headphones can meet the needs of most ordinary users. At present, the price of good wireless headphones is still relatively expensive, which should be one of the main reasons why many users are still using wired headphones. In summary, we can imagine that the wireless headphones in the future will certainly develop in the direction of miniaturization, long endurance and multi-function. Looking forward to 2019, around Qualcomms next generation of AptX adaptive audio codec and Bluetooth 5.0 technology, a series of better wireless headphones are expected to come out. It is rumored that Apple will also launch a new generation of AirPods and "studio-level" wireless earmuff headphones. The future of wireless headset market is bright. Nowadays, peoples commuting time is getting longer and longer, and the demand for multimedia continues to grow rapidly. Xiaobian believes that peoples demand for wireless headphones will only increase. Manufacturersproduct quality is also trying to keep pace with the pace. The technology industry is responding in the best way - user experience decides everything. References for this article: 1. Soundguys, 2018-12-11, USB-C headphones still suck a year later
