[Discussion] [#2 What if] Headphone jack is removed from your smartphone?

Hello Mi Fans,

Welcome to our new series, What If. In this series, we will talk about technological advancements and/or latest innovations which make you reconsider your thoughts. So let's begin with “What if the headphone jack is not there on smartphones?

To begin with, Apple is the first smartphone maker that removed headphone jacks from the device. Following the trend, many OEMs started removing the 3.5mm jacks after that.

Headphone jack saw its place since the starting of the era of the cell phone industry. It was further continued in the smartphones too. It was of great use. For feature phones, it was limited to listening to music and FM radio. But for a smartphone, it has some extra functionality such as
  • Mobile phones don’t have an inbuilt temperature sensor. But there are some external sensors available in the market which can be plugged in the headphone jack.
  • Using an external tool we can use our phones to make 3D scans of the real world.
  • Also, you can plug in an IR blaster (if your device doesn’t have)

Cool uses right. The headphone jack sports a three-channel communication interface: one channel in (for the microphone) and two channels out (for the left and right stereo channel). Listening to music gives an amazing experience on wired earphones. The sound quality through the headphone jack is also better than the USB-C port.

But no technology has proved to be permanent. Most of the premium segment devices are coming without a headphone jack. If you are used to listening to music on wired headphones, you might not prefer a smartphone without the jack. You can also use the audio splitter to route the audio to two or more output devices.

Why the headphone jack is being removed?
Following the trend, today’s need is a smartphone with high performance with a fascinating appearance. The OEMs also try to keep the devices thin, the 3.5mm audio jack might be an obstacle for them. Some smartphone manufacturers believe that removing headphone jack gives them extra space for other components like the camera and the processor. Google says the primary reason for dropping the jack is establishing a mechanical design path for the future. They want the display to get closer and closer to the edge.

Alternatives of the headphone jack

Removal of the headphone jack has opened the way for other alternatives for listening to music. For example, now USB type-C is a common thing. You can use it for listening to music. Another option is a wireless earphones/ headphones. Now you might be wondering how one will listen to FM, well there are alternatives too like the AM radio and online radio.


I am too used to wired earphones and will stick to it for at least a few more years. This trend is continuously advancing and will be slowly accepted by all. The smartphones with headphone jack might be rare in the future.

So what are your opinions, share your thoughts in the comments section.

I like the conclusion part as my thoughts are the same. I would recommend to have jacks in the smartphone as the wireless headphones are only for show they are not durable and it often needs to be charged and without charge it is useless. Jack plays very important role to those who are not only passionate to listen music but also who have a long conversation in calls for an hour or so it is difficult to use wireless headphones. I hope Redmi or Mi would not get into this change

For me, headphone jack is one of most important thing in smartphones. and I  think that wireless technology is not that much developed yet, so it affects me.

I will sorely miss the jack! The sound quality that comes out of it is still unmatched! But I am also hopeful that future technologies will improve the current experience and make the audio output as close as possible to that of the jack. On the wireless front, aptX from Qualcomm and AAC from Apple is very promising. So, all is not dark and gloomy. But this is perhaps the first time we are feeling sad about the demise of a technology, isn't it? Usually, technology changes and get better. In this case of 3.5 mm Jack, it is quite the other way round! I, too, want it to be there for a while before it falls into oblivion.

I too think the future phones will not not have earphone jack, and the alternative should be the wireless. But for that, need some more advancement in Bluetooth (in terms of relaiblility) and battery technology (in terms of size to capacity) which help make overall hasile free, uninterrupted voice and longer usage.

This trend has been in fashion for a long time and everybody knew that eventually the headphone jack would go. Its ok. Switching towards a wireless future is a step towards progress.

In my knowledge Bluetooth head phones are not up to the mark when compared with wired one, but if we want great features we have to sacrifice some thing.
