Yinyoo ZSN PRO X
Score: 76/100
JBL Endurance Run 2
Score: 78/100Rankings

The JBL Endurance Run 2 Wired earbuds deliver punchy bass and a secure, sweat-proof fit for active users. They are lightweight and feature an in-line mic, but lack wireless freedom and active noise cancellation.

The KZ ZSN Pro X is a budget hybrid IEM with a 10 mm dynamic driver and a balanced armature, offering solid bass and clear mids. Its metal construction and detachable cable add durability, but the stock cable's durability and lack of a microphone limit its convenience. Ideal for gamers and audiophiles seeking value at sub-$50.
