The return of wired headphones has sparked discussions about their continued relevance in a market increasingly dominated by true wireless earphones. Although true wireless models, like the original AirPods introduced about ten years ago, have become widespread, wired headphones have not disappeared. Some users still prefer them for their simplicity, lack of interest in advanced technology, or affordability, as many models remain very cheap, often costing no more than 20 euros. In the first seven months of 2023, nearly 2 million wired headphones were sold in France, compared to 2.2 million true wireless models. Wired headphones are often considered practical and reliable because they do not require batteries, are immediately usable, and tend to be more durable. They also avoid the costs of wireless connectivity, batteries, and digital processing. In supermarkets, most models range from 5 euros to 30 euros, which gives the impression of a good cost-performance ratio for use without limitations. Some users have even started to view the cable as a fashion accessory, popularized by celebrities like Bella Hadid or Lily-Rose Depp, under a style trend known as "Wired It Girl." True wireless headphones, on the other hand, integrate their own audio system, including digital-to-analog conversion, amplification, and signal processing. This integration allows full control over the electrical and acoustic parameters, optimizing sound quality for the specific equipment. Another advantage of wireless headphones is their consistent performance, as the sound remains the same regardless of the source, unlike wired headphones, which depend on the quality of the headphone output used. Wireless headphones do face some challenges, such as audio-video latency caused by Bluetooth, which can be addressed using a USB-C 2.4 GHz dongle. This issue mainly affects gaming, but most major audiovisual platforms effectively compensate for Bluetooth latency. A common misconception is that wired headphones provide the best sound quality, but the cable only transmits the signal it receives. The digital-to-analog converters and amplifiers in smartphones are often limited in their dynamic range, which can affect the sound quality. The idea that wired headphones are inherently better at low prices does not hold up under closer examination. High-performing models rely on quality transducers, serious acoustic design, and careful ergonomics, which have their own costs. Many entry-level wired headphones, including the popular Apple EarPods, are designed for reliability and universal compatibility rather than sound performance. Similarly, some low-cost true wireless headphones offer sound quality that surpasses that of wired models at the same price. For those seeking the best balance between sound, comfort, and functionality without extra investment, wireless headphones are increasingly seen as the most rational choice. However, wired headphones remain relevant for basic use or for those who choose them for philosophical or personal reasons.
