In the market for in-ear headphones, Sony has just launched the IER-EX15C model, featuring a USB-C interface designed for users who prioritize convenience and decent sound quality. This pair of headphones is perfect for everyday music listening, phone calls, and multimedia viewing, catering to a variety of usage scenarios.
The USB-C design of the IER-EX15C allows it to directly connect with a wide range of mainstream smartphones, tablets, and laptops without the hassle of complex pairing steps—just plug it in and it’s ready to go. Plus, you don’t have to worry about charging the headphones, which tackles the common issue of short battery life in wireless earphones. More importantly, this wired connection method ensures stable signal transmission, providing users with a zero-delay audio playback and calling experience.
The design of the headphones is compact and lightweight, featuring three different sizes of mixed silicone ear tips that can be adjusted according to the user's ear canal size, ensuring stability while wearing and enhancing comfort for prolonged use. In addition, the IER-EX15C is equipped with a wire adjuster and a serrated wire, effectively reducing tangling during everyday use, making storage in pockets or backpacks much more convenient.
In terms of sound quality, the IER-EX15C is equipped with a 5mm driver and a highly flexible diaphragm. This combination delivers a relatively balanced musical experience within its price range, particularly excelling in the bass department. Vocals are clear and distinct, almost unaffected by background music, making it suitable for the everyday listening needs of most people.
Additionally, the headphones feature an integrated in-line control design, allowing users to easily manage playback, pause, volume adjustment, mute, and answer calls through the control buttons without the need to frequently take out their devices. This makes them especially convenient for use during commutes or at the office.
The IER-EX15C offers up to four color options: black, white, blue, and pink, allowing users to mix and match according to their personal style.
The selling price is HK$159.
