The analog audio and the 3.5 mm jack is required for the phones' built in FM Radio.
Unless the headphones have build in dac and amp they are useless wireless
Great article from Prasad! Well done and congratulations for such a very informative article! Please keep it up for future too, thank you!
Seriously, I mean seriously, you should STOP using the smartphone right NOW! As that thing is absolutely not for you. Get a DUMB phone dude!
USB audio is bullshit, because for example if you plug your earbuds in your phone, you won't be able to use the USB port simultaneously for other tasks, like charging, using USB OTG devices, ...
Wireless audio is bullshit, because it requires the other device to have it's own built in battery, which will degrade and die over time. And wireless connection always consumes more battery power.
So keep using the 3.5mm audio jack and USB port separated forever! Unfortunately those who created the idea of USB audio and/or those who support it, they have NO common sense. I hate these idiotic trends.
But it's just about Apple devices, for now. I hope LG and other Android manufacturers will not drop the 3.5mm audio jack. Let it be another iPhone specific failure / limitation.
I'm sure that the few square millimeters won't change anything. In the apple case the profits from new license would be the most important reason to switch. and after that comes the advertising and how Jony Ive would talk about the superior design of the connector. Just remember how apple charges 25$ for a lightening cable that has nothing over a standard micro USB.
zodiacfml, 27 Jun 2016I could have agreed with the Bluetooth/wireless part, but the hassle of the wires was just tra... moreWireless audio is not the answer. I prefer having a 3ft. audio cable than reducing the charging life to half and being stuck to a power plug with 2 devices instead of 1. The wireless transport will suck power on both ends.
Not to mention the bulkiness of wireless headphones.
All of this while accepting the compromise of Bluetooth sound compression: while walking and bike riding, you should allow the outside noise for safety reasons, thus audiophile headphone costs are unjustified (and if you do have them....would you risk damaging them?)
Now I know I'm not a big fan of usb audio but I'm sure I can live with it given the right circumstances. However, when I'll have to forsake my audio in order to get a charge, then it'll be a big problem for me and I'm sure that goes for all the headphone lovers.
Its only a matter of time before the majority of the smartphone brands swim with the tide of USB audio.
I Do hope that they take the opinions of the users into consideration.
I'm voting for 3.5mm jack, maybe xiaomi/Samsung/ oneplus won't ditch this. adding the port not going to make your device any more slimmer..... and yeah, this is also my hate for Apple
Finally someone mentioned it !! First time i read about Apple's "revolutionary" move (every stale move from Apple is somehow revolutionary) I thought didn't I use same tech with my Nokia N70 or the world really has really short memory !! Though I am a big Samsung fan now, but still Thank You Nokia for really being revolutionary (except recognising the power of touchscreens. Thank u Apple for that one.)
What a great article this is! Very informative! I never knew (or even cared about before) how audio is being processed and these basics mentioned are enough to understand the function and how significant each parts are in audio production. I hope gsmarena continues to do articles like this where they expound and explain how things work inside our smartphones which we usually take for granted for all we do is smartphone content consumption. These awareness is i think necessary for each of us to greatly appreciate the functions of smartphones (and other tech for that matter) and we'll have much more knowledge and power which will make us subconsciously vigilant to smartphone manufacturers "gimmicks." I am hoping these kind of articles will become a regular thing here in gsmarena. Thanks and kudos! =)
It's Apple dude, Apple...
They are greedy company...
They rid the 3.5 mm jack, iphone don't need a dac inside, cheaper production cost... Greater profit
I guess the 3.5" jack will be the magic feature only for the iPhone Pro.
Well for the iPhone users omitting the jack is total disaster.
I have seen mostly iPhone users on parties , locals, weddings, pubs an so, to ask to be connected to the PA to play their own music from their iPhones. And they are always so annoying to demand it.
If the jack is omitted on the next iPhone and they don't have adapter with them , they will go crazy.
So what is the problem to have both options?
Why whole article about this BS ???
3.5mm jacks, usb jacks, wireless etc...these companies will just push more to earn more, so for me ? I think I should stick to what I am comfortable (for now) and go with the flow, well, floppy disk and compact disk dominated before, and now what do we have usb storage or like mmc micros sd..I mean technology evolves faster..so I myself would stick for the 3.5mm jack for now.....till the time comes that it is long gone...go with the flow...
What the point ditching then 2.5mm then?? Phones will still need audio codec chip for onboard earpiece and loud speakers or the'll ditch them as well and make all the phone users talk using headphones/earphones??
Phone trends sounds and feels more like Kim.K story these days....lol
