What Phones Have A Built In Dac

Minor apologies for two quick updates to this 'reference' article in a few days, merely I've added the rather fantabulous Samsung Type C to 3.5mm DAC/dongle, plus made numerous extra tweaks to the table, including quoting maximum sample rates and resolution where known. Here I look at wired sound quality from smartphone iii.5mm jacks (where they take one) and from improver, plug-in DACs/dongles (where digital output is the but wired fashion forwards). Worth bookmarking, hopefully, and coming back to later in 2021, since I'll go along updating it every bit needed.

(Original opening paragraph!): Despite Apple's (and and then Google's) attempts to quosh the humble wired three.5mm sound jack on modernistic smartphones (and copied by many others), plenty of smartphones are withal sold with jacks and with DACs feeding whatever wired headphones y'all intendance to plug in. Potentially college quality, and certainly no problems with drained batteries or lost AirPods (etc.) In this large 2021 update of an commodity from 24 months ago, I test a variety of existing smartphones and (specially) standalone DAC/dongles, the former where they have jacks and the latter where output is digital and needs converting. In other words, here's how to make sure you can plug in your favourite wired 'cans' for years to come!

Note: I've kept the original comments intact, but please practise flake in with new ones!

________

As always, writing about audio isn't petty, since your ears can't exist here to try things and comment with me. So I'll have to run through some of my methodology before launching into bodily tests.

A few basics though. I'yard testing wired audio hither, hopefully through a 3.5mm socket in the phone. But, recognising that in 2021 near Android phones over most £500 (plus all recent iPhones) have no 3.5mm socket, I've also gear up nearly testing external DACs/dongles*.

* from one of our own recent reviews:

The 'disruptive' element comes in that many Chinese phone manufacturers (e.g. Huawei) have a DAC (i.e. digital music to analogue audio) within the phone and output music through unused pins (SBU1/SBU2, plus voltages on D+ and D-), meaning that a 'dumb' adapter for £1 on eBay that literally passes through connections to a 3.5mm socket and with no active circuits, will piece of work. This is OK if you accept such a phone simply it's worth noting that this approach to audio in a Type C globe isn't recommended (by the industry). And if you lot plug such a impaired adapter into a Google Pixel or Samsung or Nokia (etc) flagship phone and so zero will happen.

Digitally cleaner, more standard, and with higher sound quality and lower noise, is for digital audio streams to leave the Type C jack via USB 2/3 information pins and so a DAC in an accompaniment (or headphones themselves) can do the conversion to analogue away from the electronic noise of the phone's chipset.

Why 'DAC/dongle' as a term? Its impuissant, but 'dongle' on its own is misleading because information technology can expect identical, whether dumb or with a DAC. The easiest way to tell up front is to look at the price. Dongles with DACs in (equally here) are around the £ten marking at minimum, since they incorporate plenty of advanced circuitry. And oft veer through £20 upwardly, with £100 or more for actually serious (and beefy) kit. Whereas the dumb analogue dongles are dirt inexpensive and much less than £10. That's how you tell, short of them having them in your mitt!

In each case, the smartphone's music awarding (or video, etc.) takes a digital music source (whether local or streaming) and uses the Digital to Analog Conversion (DAC) capabilities of the telephone's hardware (either in the main chipset or as a standalone sub-organisation or perhaps in a DAC dongle) to produce 'analog' voltages, for left and right channels and with a common ground. Leaving aside microphone complications, these analog voltages are turned into tiny speaker movements in your chosen headphones and - hopefully - you hear music in your ears.

And if that seems complicated enough, there are plenty of other variables:

• The digital source might be compromised, east.one thousand. low bitrate or a poor codec, or simply a poor original (e.g. off vinyl) when the source was created.
  
• The headphones used are very of import, since 99% of the wired headphones I run into used out in public are pretty ropey. For example, use some cheap outer-ear headphones (eastward.chiliad. Apple tree wired in-box white headphones, or clones thereof) or even cheap in-ear headphones (over again, frequently provided in the box) and you'll be missing many audio frequencies (bass and high terminate), in add-on to also hearing noise 'pollution' from the world around yous.
  
• Your own hearing may be compromised, either through age or over-exposure to loud sounds or music(!)

Now, there's not much that tin be done for the last point, but I can certainly address the commencement two (and you should also), in selecting my examination cloth and equipment. I tried to pick from a range of music genres, settling on, all at 320kbps MP3:

• Kari Jobe'due south 'Majestic' live album, rail "Hands to the Heavens" - the production on this is superb and there's plenty of bass and high end to exam.
• Have That's "Attain out", from their Cute Globe album - again exemplary production and a full range of frequencies to listen for.
• "Vierne: Messe solenelle op. sixteen: Kyrie" from Cathedrale Notre-Dame De Paris - I was there and know how a total choir and organ in that amazing place should sound!

I did my listening through my much-loved and much-used Veho Z-eight over-ear studio headphones - they sound fantastic and equally I write this (by coincidence!) are currently on Amazon United kingdom, at £29. But saying. These were originally over £50. Hither's my Z-8 review from back in the twenty-four hours. I know, I know, audiophiles are going to say that I needed to use £200+ headphones as my reference, but I trust these Z-viii and have lived with them for several years. I as well tested with my (equally loved simply smaller) Marshall Major II, which work in wired mode (here) and Bluetooth if needed (e.grand. when exercising). The Major II are now hard to get, but I meet the Marshall Major Iii wired set are just £57 on Amazon Britain.

And and then on with the testing. Evidently, you're not here with me to listen yourselves (and doing a video or audio sample wouldn't help, since y'all'd and so be at the mercy of the audio capabilities of even so yous watched/listened), so you lot'll have to rely on my scoring. Hey, it'due south all just a guide and I'thousand more interested in the relative differences, i.e which phones/DACs are improve and past what margin?

Finally, I can only written report on what I have to manus. You'll have to infer audio quality from related hardware. I do give some idea below - manufacturers ordinarily re-use the aforementioned chipsets and (of course) music and video applications across their ranges. The list just constitutes data points.

And, this being AAWP, I'll get-go with some Windows-powered phones, and so follow with other candidates, including some from this year. I've coloured any score of 35 or over in green, to betoken 'good'. Anything scoring 34 or less is boilerplate or worse, so consider with caution, etc.

Further notes:

• There likewise be sizeable external DACs/amplifiers. These are typically as large as a telephone and cost between £50 and £one thousand (e.g. this 'pro' offer from iFi) and are intended for professional apply. Size and weight proclude them from this comparison, but I'one thousand sure they're also proficient - if expensive - options if you want ultimate quality.
  
• Some 'pro' DAC dongles of like size to the ones tested below are available at high price (due east.1000. the THX one at £200) - I've applied for review hardware and volition study back here on AAWP/AAM!
  
• Although I've quoted 'maximum sound resolution' below (chip-depth of sampling and sampling rate), where known , they're but guides - ultimately it was down to my ears, notably when considering volume, i.e. actual 'oomph'!
  
• I'd previously had the Google DAC/dongle supplied with the Pixels, merely the confusion over which of the ii possible versions that were made has caused me to remove that line in the table. I'll try and get one in once more - making sure which exact version I have - and so add information technology to the table in the future.

Notes:
All phones were tested with 'apartment' EQ, i.due east. testing default output. Nearly smartphones (including the Lumias here) have an extra software Equaliser than tin can be practical to some (or all) output, but these are just software EQ furnishings and muddy the testing waters too much. This is analagous to me testing phone cameras on 'auto' and not in a 'pro' mode, where things get exponentially more hard to compare.
§  Past which I hateful other phone models which will sound the same, usually because they're sister devices in a range.
+  Unlike DACs put out different amounts of 'oomph'. A decent audio amplifier volition hands drive headphones with 'volume to spare', while on lesser chipsets you'll be at maximum volume on the phone and no headroom to increase information technology further. For instance, the Alcatel IDOL 4 Pro puts out and then much book in my headphones at 23/30 while the Wileyfox Pro at xxx/30 isn't loud enough.
++  I'm listening for rendering bass right down to 20Hz and lower - I like to hear bass guitar notes in their natural entirety, equally if I'grand standing by the bass amp (I play guitar and bass) and hearing the subtleties. Most headsets fall downward here, providing insufficient (or software-additional) bass.
*  I'm listening for details in voices and percussion, with no compression artefacts - again, as if I was in forepart of the singers or percussion, hearing them 'live'.
**  Poor smartphone audio often results in weak stereo separation, with besides much common ground between channels. I'm also rating hither for an overall impression of allegiance. And, yeah, enjoyment.
*** The Gemini version is marked down because of horrible static on the jack when music isn't playing. Conspicuously electronic problems in the design (and that's non counting Planet wiring the stereo speakers out of stage on BOTH devices - gah!)

Verdict

What became apparent, somewhat surprisingly, is that music output and enjoyment on smartphones is less about absolute audio rendering, i.e. less about how well the full range of frequencies could be output for a given audio source (though there are differences), and more well-nigh sheer volume/voltage. Nosotros've all been there - in a noisy city street and trying to actually savour our music and even at a phone's maximum output it's only just loud plenty. This is where the best music phones have volume to spare. (And no, I'm not going down the 'loud music will damage your hearing' route - I'm assuming that y'all're existence sensible and not overdoing it or for too long a sustained menses.)

Nigh phones in 2020/21 don't ship with defended DACs or power amps - they rely on the DAC in the main SoC (System on a Chip), i.eastward. audio rendering is now included at 'good enough' levels in the Snapdragon/Mediatek processor so in that location's no perceived demand to take actress audio chips. As a result, many of the scores from 2020/21 smartphones are similar. At (say) 33 points above, they're not spectacular though - audio is designed for the human being in the (quietish) street listening to the Acme 40 'tunes'. Anyone wanting to hear music properly needs to look farther. To a smartphone with better DAC, or (more than likely) to plug in a Lightning or Type C DAC/dongle, with some decent candidates above.

The IDOL 4 Pro, my favourite Windows 10 Mobile phone, and the music-specialist (and now sadly obsolete) Marshall London, running Android, came height, both with defended music fries/amplifiers and some serious output. Along with the (sadly discontinued) Sonata HD Ii DAC, which still stuns . Plus whatsoever of the Lumias from dorsum in the day - Nokia and then Microsoft knew how to put together a smartphone (information technology'southward not merely imaging). Sigh. The Sony Xperia v II is a modernistic flagship that is impressive in many means, not to the lowest degree with a dedicated DAC/power-amp, though its lack of Qi charging might be a showstopper for some regular readers.

Of the (withal available) Blazon C DAC-dongles, the Samsung one struck the best balance of book and fidelity. It would exist easy to dismiss such tiny electronic components, merely many tin can admittedly practice the job (the Apple Type C one is odd, with universally panned depression book output). It'due south proficient to know that if we do end up going downward a jackless, Blazon C-only route, that wired audio quality doesn't have to suffer, even if we do have to put up with actress $.25 of wire and plastic hanging off our phones.

Although I'll be testing some more expensive DACs in the hereafter, I love the £10 price point considering these are small-scale gadgets that WILL get lost in daily use. I got up to about five Apple Lightning ones before I started finding them every bit fast as I lost them! And at £10 each yous really can buy a few and accept them semi-permanently on the end of each favourite pair of wired headphones.

PS. Of annotation in 2021 is that Bluetooth v is now firmly established and (after a decade of my criticising information technology) wireless sound is demonstrably good enough, depending on the DAC in the earpieces and speaker set up-up, see my various assorted Bluetooth audio reviews here on AAWP:
