Lightning Headphones Sound Better. Much Better
Finally, there's maybe the biggest benefit of the multitasking Lightning cable — it transfers audio files with less data loss. That's a jargon-y way of saying that music comes through cleaner. That's especially important for high-quality digital music, the kind of huge-bitrate tracks that can sound amazing when pumped through the right home audio system, with the requisite receiver, preamp, digital-to-analog converter and loudspeakers, but that sound merely good when squeezed through headphones. Where standard earphones left much of that extra data behind, Lightning earphones will retain the quality of tracks. This also means that high-resolution audio (HRA), which is a significant step up from the quality of streaming music or even CDs, will finally hit the mainstream.
Until now, listening to HRA on headphones has required being tethered to a PC, or buying a dedicated music player, or else pulling off an arcane techie runaround, using obtuse apps to store and play HRA tracks on devices that aren't set up to natively play them, such as the previous iPhone. Even then, Lightning headphones were the best way to guarantee that all that upgraded audio quality was surviving the trip from the phone to your ears. But now that Lightning cables are the iPhone's only wired connection for earphones, it's expected that the iPhone 7 will play HRA natively, and that this next level of audio bliss will be available to everyone.
