EDR1 Metal Subwoofer In-Ear Headphones: Wired Sound with 8mm Drivers and Microphone Option

These EDR1 in-ear headphones provide a straightforward, wired audio connection for a variety of portable devices. Designed with a focus on core specifications like an 8mm driver unit and a 5-28,000Hz frequency response, they aim to deliver clear sound for music and media playback. The inclusion of a model with an integrated microphone expands their utility to hands-free calling. With a universal 3.5mm L-bend plug and a cable length of approximately 1.2 metres, they offer a practical and tangle-resistant solution for daily use with mobile phones, MP3 players, tablets, and laptops, eliminating the need for battery charging or wireless pairing.

Features and Construction

The build of these headphones centres on their stated materials and electrical specifications, which define their performance and user experience. The components are selected for durability and function within their design category.

Material and Build

The ear tips utilise TPE (Thermoplastic Elastomer) that is fire-retardant, a practical choice that contributes to user safety and provides a flexible seal for improved in-ear fit and passive noise isolation. The headphone wire is sheathed in imported silicone, a material noted for its resistance to kinking and everyday wear, helping to maintain cable integrity over time. The metal-referenced subwoofer housing likely contributes to the structural rigidity of the driver enclosure.

Size and Practical Fit

Key physical dimensions include the 8mm diameter of the sound driver (horn) and the 1.2-metre cable length, with a tolerance of ±0.3 metres. This cable length offers a practical reach between a device in a pocket or on a desk and the user's ears. The in-ear wearing method and TPE ear tips are designed to secure the headphones comfortably during movement, making them suitable for commuting, workouts, or general daily activities.

Uses and Placement

The product's specifications directly support its application across common audio scenarios, from casual listening to communication.

Event or Professional Use

With a sensitivity of 120dB and low 16Ω impedance, these headphones can be driven effectively by most smartphones, MP3 players, and computers without requiring a dedicated amplifier. This makes them a viable, low-cost option for backup monitoring, casual podcast listening, or as a spare headset for basic communication tasks in environments where wireless connectivity is unreliable or undesirable.

Everyday Home Use

At home, the 3.5mm wired connection provides a lag-free audio link for watching videos on a tablet, listening to music while doing chores, or gaming on a console or PC. The model equipped with a microphone adds functionality for voice chats, online meetings, or hands-free phone calls. The simple plug-and-play nature requires no software setup, making them accessible for all users.

Benefits and Buying Value

The value of these headphones lies in their defined specifications, material choices, and the clear options provided, allowing for an informed purchase based on concrete needs.

Reuse and Low Maintenance

As a wired product, they require no batteries, charging cables, or Bluetooth pairing, simplifying their use and reducing electronic waste associated with disposable batteries. The silicone cable jacket and TPE ear tips are materials chosen for their resistance to degradation, suggesting a focus on product longevity through material selection rather than unstated premium claims.

Why Choose This Product

Choosing these headphones is a decision based on their explicit specs: the 8mm driver size and wide frequency range for sound, the option for a built-in microphone, and the practical 1.2m wired connection. They represent a transparent offering where the key differentiators—driver size, cable material, microphone option—are presented upfront, allowing buyers to match the product to their need for a reliable, specification-led audio accessory without unspecified performance promises.
