The AKG K240 Studio headphones deliver precise, detailed audio with a semi-open design, making them ideal for professional mixing and mastering at a budget price. Their trade-offs include sound leakage, lower sensitivity that may need an amp, and a non-foldable build. Suited for audio engineers and musicians who prioritize sound accuracy over portability.
The OneOdio A71 is a wired, closed-back over-ear headphone with a detachable boom mic, offering a wide soundstage and strong bass at a budget price. Its plasticky construction and occasional reliability issues may deter users seeking long-term durability. Best suited for gamers and entry-level home-studio users who value portability and a built-in mic.

Professional reviewers consistently commend the K240 Studio for its precise, detailed sound and natural imaging, attributing this to the Varimotion transducers. They note the headphones are easy to drive, feature a detachable cable, and offer replaceable earpads, making them serviceable. Criticisms focus on the semi-open design's sound leakage, the vinyl earpads' durability issues, and the relatively low sensitivity that can demand extra amplification.
Everyday users appreciate the K240 Studio's affordable price, comfortable fit, and balanced sound for mixing and overdubbing. Common praise highlights the replaceable parts and overall value. Recurring complaints involve earpad wear, sound leakage in shared spaces, and occasional need for an amp to reach desired loudness.
Professional reviewers praise the A71 for its surprisingly wide soundstage, solid isolation and strong bass-vocal balance, especially given its low price. However, they criticize the plasticky construction, inconsistent spec listings and potential durability concerns, noting it feels less robust than benchmark models like the ATH-M50x.
Everyday users love the comfort of the rotatable pads, the effective isolation and the convenience of the foldable design, but many complain about early-life failures such as speaker breakage and the overall heavy, plasticky feel of the headphones.
