Who First Dropped the 3.5mm Headphone Jack? Inside the Wired Revival
A wave of nostalgia has revived wired headphones as young users question who started removing the 3.5mm jack, while market data shows a sales rebound, manufacturers cite technical reasons, and the article dissects the audio, business and cultural forces behind the trend.
Market reversal of wired headphones
Circana reports that after five consecutive years of decline, wired‑earphone sales grew 3 % in 2025 and surged in the first quarter of 2026, making the segment the fastest‑growing category in the overall earphone market.
Timeline of 3.5 mm jack removal
2008 – HTC G1 (Android) became the world’s first smartphone without a 3.5 mm audio jack.
2012 – OPPO Finder launched without a jack (no market impact).
2014 – OPPO R5 launched without a jack (no market impact).
2016 – Apple announced the iPhone 7 without a jack, popularising the change.
Subsequent years – Xiaomi, Huawei and other Chinese manufacturers followed, eliminating the jack from flagship devices.
Despite the narrative that removing the jack is required for waterproofing and internal‑space savings, Samsung’s flagship phones achieved IP68 protection while retaining a 3.5 mm jack and did not become noticeably thicker.
Technical comparison
Wired headphones : transmit an analog signal directly over copper. Bandwidth is effectively unlimited, there is no compression, and latency is virtually zero.
Bluetooth headphones : transmit digital audio over a limited‑bandwidth radio link, requiring audio compression and decompression. Typical latency is 30–50 ms. In crowded RF environments (e.g., subways, offices) bitrate may drop, further degrading audio quality.
Business implications
Eliminating the jack forces users to buy either a proprietary adapter or Bluetooth earbuds, creating a new market worth several hundred billion yuan. Wired earphones remain inexpensive, require no charging, and provide a reliable plug‑and‑play experience.
Standard‑level advantages of the 3.5 mm interface
The 3.5 mm connector is a 70‑year‑old open standard with no licensing fees or ecosystem lock‑in. It works with low‑cost earphones (≈¥9) as well as high‑end monitoring headphones, delivering identical electrical performance.
User‑driven resurgence
Many users cite audio fidelity, zero‑latency gaming, and the inconvenience of charging Bluetooth earbuds as reasons for returning to wired solutions. The cultural dimension—white‑cable aesthetics, cable customization, and the perception of wired earphones as a fashion statement—further fuels demand.
