By the end of 2025, no flagship phone above $800 shipped with a 3.5mm headphone jack. The transition that started a decade ago with the iPhone 7 in 2016 — controversially, with the famous "courage" framing — finished quietly in the premium segment in 2025. The mid-range (Pixel 9a, Galaxy A56, Motorola Edge 50) still ships it; the budget tier (under $400) almost universally retained it. But the migration in flagships is complete: Apple, Samsung, Google, OnePlus, Xiaomi, Vivo, Oppo all dropped it from their $800+ SKUs by late 2025.
The question worth asking nine years after iPhone 7 isn't whether the jack should have stayed — that argument is over — but what we actually lost and gained when it left.
What the loss cost users
Less than the noise around it suggested. A USB-C DAC dongle costs $10–$30 retail and delivers measurably better sound than nearly every phone's built-in jack ever did. The Hiby FC4 ($35) outputs cleaner signal than any iPhone 6S ever could, and the Apple USB-C to 3.5mm adapter ($9) is — embarrassingly — engineered to a standard most Android phones' internal jacks couldn't match. So the loss is convenience, not signal quality.
Three real frictions remain:
- Carrying the dongle: it's another small thing to lose. Most users buy three over a phone lifetime.
- Using wired headphones while charging: requires a USB-C splitter ($20). Solvable but ugly.
- Latency in pro-audio contexts: musicians using guitar interfaces or monitoring through a phone benefit from a wired analog path. USB-C DAC works but adds 5–10 ms of conversion latency.
What replaced it
- Bluetooth LE Audio with LC3 codec — the modern Bluetooth audio standard. Lower power, broadcast support (Auracast), latency under 100 ms with good implementations. By 2026 LE Audio is in every flagship phone and most $200+ earbuds.
- USB-C DACs — Hiby, FiiO, AudioQuest DragonFly. Universally better than the built-in 3.5mm jack of any sub-2020 phone. A $30 dongle outperforms a $1,200 phone's onboard DAC.
- Wireless lossless audio — Snapdragon Sound with aptX Lossless on Android; Apple lossless over wired USB-C on iOS. Niche but real for audiophiles who care.
- Wired USB-C headphones — these exist (the Beyerdynamic DT 700 PRO X has USB-C; Apple's own USB-C EarPods are surprisingly good for $19). Niche market.
What was lost
- Friction: plugging in is faster than pairing. Always was. The 2-second pair time isn't bad, but the 0.5-second plug-in time was better.
- No charging: wired audio doesn't need batteries, never dies, never needs firmware updates.
- Longevity: a 5-year-old pair of $300 wired headphones still works on a brand-new phone via dongle. A 5-year-old pair of $300 wireless headphones (e.g., 2020 Sony WF-1000XM4) often won't multipoint with current OS standards, may not get firmware updates, and is approaching battery end-of-life.
- Universal compatibility: a 3.5mm jack worked with every device made for the past 60 years. No app, no firmware, no pairing.
- Simplicity for kids and elderly users: pairing remains a non-trivial UX for non-tech-native users.
What was gained (besides the marketing line)
- Larger batteries: a 3.5mm jack costs ~3 mm² of internal board space and ~2 mm of depth. That space, multiplied across the volume freed up, went to bigger batteries. Modern flagships average 16–22% larger battery capacity than 2016-era equivalents.
- Better water resistance: a port removed is a sealing problem solved. IP68 ratings are universal on flagships now; in 2016 they were premium-only.
- Cleaner industrial design: one fewer port to design around.
- Better DACs in dongles: separating the DAC from the phone enabled real audiophile DACs in the $30–$300 range.
The real shift
The jack didn't disappear because manufacturers hated it. It disappeared because internal phone space is the most contested real estate in consumer electronics. A jack costs ~3 mm² of board space and ~2 mm of depth. That space went to bigger batteries — see our silicon-carbon battery report — to better water resistance, to additional camera modules. The trade was unsentimental engineering.
For users who care, a $30 USB-C DAC is the answer. For users who don't, AirPods Pro 3 and Pixel Buds Pro 2 are now genuinely excellent. The wired audio era ended quietly because, by 2026, the alternatives are good enough.
