When and why did smartphones stop including the traditional headphone jack? Many users think it was Apple that started this trend with its flagship iPhone, revolutionizing the mobile industry by eliminating the familiar 3,5 mm jack. However, the story is longer and more complex, and China, with brands like Oppo, played a fundamental role in this technological transformation that today seems irreversible.
The true pioneer: Oppo and the withdrawal of the jack
El Oppo Finder It was the first modern smartphone to be released without the traditional 3,5mm headphone port. This innovation marked a before and after in smartphone design, especially since the goal was to achieve an extremely thin device. With a thickness that astonished the public and the industry, the Oppo Finder set a record and challenged established rules.
A couple of years later, Oppo repeated its commitment to maximum thinness with the Oppo R5, further reducing the thickness and consolidating its position as a manufacturer willing to sacrificing “traditional” features in favor of aesthetics and advanced design.
The absence of a headphone jack on these devices was neither an accident nor a mere whim, but a strategic decision to differentiate itself from the competition. Although other manufacturers still relied on the 3,5 mm connector, Oppo went all in. innovate in design and stand out in a saturated market.
Why did Oppo decide to remove the headphone jack?
The main reason that prompted Oppo to remove the connector was achieve the world's thinnest smartphoneOppo's engineers faced a technical challenge: the 3,5mm port took up too much space and limited the phone's ability to reduce its thickness. So, they decided to ditch the jack rather than abandon an aesthetic trend.
The Oppo Finder was barely over 6 mm thick, while the Oppo R5 was surprisingly thin for its time. This compromise had its drawbacks, as wireless technology wasn't yet widely available. To address this, Oppo included a micro-USB to 3,5 mm jack adapter, allowing the use of traditional headphones. In addition, this movement was key to understanding how The first smartphones without a headphone jack arrive.
It should be noted that eliminating the jack meant anticipating by several years a trend that would later become the norm in the mobile industry. Oppo's move was risky and daring, but it showed that innovation often involves abandoning the established.
Other aspiring pioneers and the industry context
In the evolution towards thinner and more advanced smartphones, Other brands also experimented with the absence of a headphone portHowever, many earlier devices did not fit contemporary smartphone standards, as they had different form factors or physical keyboards.
Mention of the HTC Dream, for example, often comes up in discussions on this topic. This model included headphone connectivity, but not in the traditional sense, and its design was far from what we consider a modern smartphone today.
Brands like Vivo also fought for the title of thinnest phone, although in some cases they kept the jack at the expense of a less extreme design. But Oppo's radical commitment to thinness and aesthetics made the difference and laid the foundation for the current trend.
The Apple revolution and the globalization of “fashion” without Jack
Although Oppo was a pioneer in doing away with the headphone jack, Apple was the one who popularized this trend and turned it into a global standard. When the Californian company introduced its model without an audio jack, it offered new technical and practical justifications: the port took up valuable internal space that could have been used for a higher-capacity battery, a precision haptic motor, or even improvements in water and dust resistance.

Apple argued that eliminating the jack gave it the freedom to evolve the device's internal design, incorporate new modules, and reduce the number of openings, which benefits IP certification and durability. Furthermore, the brand made a strong push into wireless headphones, anticipating the massive expansion of Bluetooth as a mobile audio standard.
The “Apple effect” made Other Android and industry manufacturers, which until then had resisted change, joined the trend. Samsung, Sony, Google, Xiaomi, Motorola, and others ended up eliminating the headphone jack on many of their mid- and high-end models, consolidating a change that now seems definitive and irreversible in mobile telephony.
Consequences and advantages of the disappearance of the jack
The removal of the headphone jack meant important changes in the market and in the daily lives of usersAmong the most notable advantages are:
- Increase in internal space: By eliminating a physical port, it is possible to introduce larger batteries or new components.
- Water and dust resistance: Fewer openings in the chassis make it easier to achieve high levels of protection in this regard.
- Homogenization of ports: Using USB-C or Lightning for charging and audio reduces the need for multiple cables and standardizes connections.
- Boost to wireless headphones: With the disappearance of the jack, mobile and audio brands developed Bluetooth headphones with more functions (noise cancellation, voice assistants, system integration, etc.).
However, drawbacks and criticisms also arose. A significant number of users lamented the loss of direct access to their classic headphones, facing the need for adapters or the purchase of specific models. For a better understanding, you can consult How to clean a cell phone without damaging it.
Are there alternatives to the headphone jack?
Today, users have several options for listening to music or making calls without a dedicated jack:
- Bluetooth headsets: They are the star option, with a wide variety of prices, designs and sound technologies.
- USB-C or Lightning to 3,5 mm jack adapters: They allow you to continue using classic headphones, although they add an extra accessory.
- Headphones with direct USB-C or Lightning connection: There are more and more models of this type, designed to integrate with the main port of the smartphone.
Brands like Samsung, Xiaomi, Apple, and many others offer versatile solutions, and today the wireless experience is more convenient than traditional wireless, thanks to the development of Bluetooth and the improvement in autonomy and audio quality.
Will the headphone jack return to smartphones?
La unstoppable trend Market trends suggest that the jack will remain absent from most modern devices, especially in the high- and mid-range segments. Currently, only some entry-level models or phones aimed at very specific markets retain this port for cost or segment reasons.
The reality is that manufacturers are focusing on better integrating their devices with wireless headphones and advanced audio solutions, and the development of new generations of Bluetooth and other standards only widens this gap. It's becoming less and less likely that the jack will once again be a fundamental component of smartphone design.
The path Oppo paved by eliminating the headphone jack has forever changed the way we interact with our devices. Despite initial hesitation and resistance, the industry was able to evolve and offer more convenient, versatile, and advanced alternatives, with Apple and other major brands consolidating the trend. The future of mobile audio is wireless and focused on complete integration, a reality Oppo envisioned long before others and that today is an inescapable part of our technological experience.
