There was a tech journo writing today about not missing 3.5mm audio-out sockets on phones on ‘makeuseof’, and then leaning into microSD cards and notification sliders. I never did much care about the latter, but the first two - well, we’ve banged on for years on PSC about how great it is to have them both. However, I have to admit that whenever I get my SIM card into a Sony Xperia phone here, I smile at the 3.5mm audio-out socket and dutifully put my 1TB microSD card into the slot. And then - I realise when I switch to another phone - I have not used either of them once!
I guess for some it’s a ‘nice to have rather than not’, but in today’s super-connected world and with staggeringly good Bluetooth, I wonder just how many people actually still need these things, as the journo has concluded. As for 3.5mm head/earphones, I’m really not audiophile enough to gain any advantage from a physical jack option - and I’d wager that 90% of Xperia (and other phones which claim to have great audio from the jack) users plug in gear that can’t make use of it anyway. Don’t get me wrong - it’s great tinkering fun to see it all work - but in the real world, it’s more likely to annoy by catching cables on door handles or tripping over them, crashing the phone to the floor when going to put the kettle on, than it is of any real use!
Of course, there will be niche cases and people who can and do appreciate the difference - and do have top-notch quality gear that works beautifully in tandem - but it feels like they will be a huge minority. Plugging it into a speaker maybe - well, OK, same applies really - great tinkering fun and nostalgia, but real-world? Of course, everyone is using Bluetooth - and BT on an Xperia phone (and most others now) is staggeringly reliable and good with a long range (usually) that will get you way past the kitchen kettle and most likely to the end of your long, long garden!
Moving away from Xperia, the chap argues that given the quality of one’s phone’s inbuilt DAC, the volume coming out of the 3.5mm jack might not be that high either. "If you like to use high-impedance headphones or quality IEMs, you'll find that the stock headphone audio-out doesn't have the power needed to reach their full potential. Additionally, since Android downsamples hi-res audio files played out of an inbuilt headphone jack, you're missing out on the best quality if you use it. Android often defaults to 48kHz resampling for hi-res audio files played through a default device output, which is higher than CD quality. However, if you want to play files up to 192kHz/24-bit at their full quality, you'll need an external USB DAC. So, despite having a 3.5mm audio-out right there on my phone, I found myself choosing to plug in a USB-C DAC instead" he said. I’m not smart (or audiophile) enough to know if all that is true, but he seems to know what he’s on about!
So then we come to the microSD card function. I live in a world where Plex is my friend. When I’m at home or out and about, as long as my router is on at base, I can just stream whatever I want, wherever I am. Anything from my 16TB HDD. So when do I ever need a microSD memory card? Well, for me and my life, never! But, again, there are people who live in dodgy connection zones or travel through them, and I guess that could impact their life if they can't get to essential files they need for their presentation the next morning. The other point, though, is that baseline storage on phones is going up and appears to be peaking generally, at least out of China, at 512GB now. And that’s surely plenty of movie/TV/music space for anyone planning a night away - or just having it there in case.
But then I suppose if you don’t have it (and/or you haven’t planned ahead for some kooky reason) you could always do something to pass the time. Like going for a pint. Or chatting with another human being. Anyway, the point is that I tend to agree on this based on my behaviour. Not once (beyond testing for reviews) probably in the last 5 years have I actually used data on a microSD card, nor plugged anything into a 3.5mm audio jack! Maybe you’re different.
