## Long description

These Aiwa ESTM-20RD wired in-ear headphones deliver compact, reliable sound for calls, music, sports and everyday use.

The lightweight construction (13 g) and 1.2 m tangle-resistant cable make them convenient for commuting and workouts. The package includes silicone eartips and a velcro strap for cable management.
Advantages
The headphones use a 10 mm neodymium driver and an ergonomic 30° fit to provide clear audio and pronounced bass in a small form factor. A wired 3.5 mm connection ensures compatibility with most devices without the need for pairing, while the included silicone tips improve comfort and passive isolation. The lightweight, low-profile design is suitable for extended wear and active use.
Suitable for
 Hands-free voice calls on smartphones and tablets
 Listening to music during commuting
 Light to moderate workouts and outdoor activities
 Everyday use where a wired 3.5 mm connection is available
When it may not be suitable
These wired in-ear headphones require a device with a 3.5 mm audio jack and are not suitable for users who need wireless or noise-cancelling functionality. They provide passive isolation but are not designed for professional studio monitoring or environments needing advanced active noise reduction.
