Options range from no active noise control on wired earbuds to wireless models with various noise features, including noise cancelling, active noise cancellation (ANC), and Transparency modes that let outside sound in when needed.
Many models list sweat‑ or water‑resistant protection (often described as sweat‑resistant or water‑resistant). Some in‑ear models are rated IPX4 or IP54, while a few listings show no water‑resistance rating.
Fit options include single‑fit designs and multi‑tip offerings such as three, four, or even five tip sizes (usually silicone or foam) to help create a secure seal and improve comfort for different ear shapes.
Wireless models reference Bluetooth technology, with some listings specifically noting Bluetooth 5.3 or Class 1 Bluetooth for extended range.
Many include a built‑in microphone plus on‑device controls for calls and volume. Some use a force/press sensor, while others have on‑ear buttons to answer/end calls and control playback.
