Score: 79/100Rankings

The Keephifi KZ DQS is an entry-level single-dynamic-driver IEM that delivers a balanced, high-resolution soundstage with a semi-open design. Its lightweight metal construction and detachable cable make it attractive for audiophiles on a budget, though the lack of water resistance and a thin stock cable are drawbacks. Ideal for listeners who value detail and comfort over extreme bass or rugged use.

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.
