Last year, when it was rumoured that the then upcoming iPhone models -- 7 and 7 Plus -- won't have the 3.5mm audio jack, The Verge's Nilay Patel wrote that if Apple does do it, it would be a user-hostile and stupid move. When those iPhone models were official announced, they indeed didn't have the audio jack. Earlier this week, Android-maker Google announced the Pixel 2 and Pixel 2 XL smartphones that also don't feature the decades-old audio jack either, a move that would likely push rest of the smartphone makers to adopt a similar change. The rationale behind killing the traditional headphones jack, both Apple and Google say, is to move to an improved technology: Bluetooth. But there is another motive at play here, it appears. Patel, writes for The Verge: As the headphone jack disappears, the obvious replacement isn't another wire with a proprietary connector like Apple's Lightning or the many incompatible and strange flavors of USB-C audio. It's Bluetooth. And Bluetooth continues to suck, for a variety of reasons. Newer phones like the iPhone 8, Galaxy S8, and the Pixel 2 have Bluetooth 5, which promises to be better, but 1. There are literally no Bluetooth 5 headphones out yet, and 2. we have definitely heard that promise before. So we'll see. To improve Bluetooth, platform vendors like Apple and Google are riffing on top of it, and that means they're building custom solutions. And building custom solutions means they're taking the opportunity to prioritize their own products, because that is a fair and rational thing for platform vendors to do. Unfortunately, what is fair and rational for platform vendors isn't always great for markets, competition, or consumers. And at the end of this road, we will have taken a simple, universal thing that enabled a vibrant market with tons of options for every consumer, and turned it into yet another limited market defined by ecosystem lock-in. The playbook is simple: last year, Apple dropped the headphone jack and replaced it with its W1 system, which is basically a custom controller chip and software management layer for Bluetooth. The exemplary set of W1 headphones is, of course, AirPods, but Apple also owns Beats, and there are a few sets of W1 Beats headphones available as well. You can still use regular Bluetooth headphones with an iPhone, and you can use AirPods as regular Bluetooth headphones, but the combination iPhone / W1 experience is obviously superior to anything else on the market. [...] Google's version of this is the Pixel Buds, a set of over-ear neckbuds that serve as basic Bluetooth headphones but gain additional capabilities when used with certain phones. Seamless fast pairing? You need Android N or higher, which most Android phones don't have.
