概要
The 30-Second Version
With an 89th percentile social proof score and a 4.5-star average from over 12,000 reviews, the AKG K240 Studio is a budget monitoring legend. It delivers a clear, neutral sound that's perfect for mixing, but its 20th percentile mic score and significant sound leakage mean it's a terrible choice for calls or public use. For around $50, it's one of the best values in studio audio, period.

実証データ
Performance
The 30mm dynamic drivers with AKG's Varimotion diaphragm deliver a frequency response from 15Hz to 25kHz. In practice, that translates to a sound that's accurate rather than artificially exciting. The semi-open back gives the low end a natural presence without the boomy exaggeration you get from closed-back competitors, and the highs are crisp enough to catch a poorly placed hi-hat in a mix. The 55Ω impedance and 104dB sensitivity mean you can drive these reasonably well from a laptop or audio interface, though a dedicated headphone amp will wake them up a bit more. The sound profile is a standout for studio work at this price, but it's not a bass cannon for casual listening. The mids are present and clear, though some users wish they had a bit more forward bite, which aligns with its solid but not top-tier sound score.

vs Competition
Stacked against the competition, the K240 Studio carves out a very specific niche. The Sony ULT WEAR and JBL Tune 670NC are both closed-back, bass-forward, and packed with features like ANC and Bluetooth, which the K240 completely lacks. If you want wireless convenience and thumping low end, those are the obvious picks. The Bose QuietComfort and Soundcore Life Q20 also dominate on comfort and noise cancellation, areas where the AKG scores in the 33rd and 34th percentiles respectively. But none of those competitors offer the same flat, analytical sound for critical listening at this price. The Sennheiser MOMENTUM 4 is in a different league for sound quality and build, but it also costs several times more. The K240's only real fight is against other budget wired studio headphones, and in that ring, it's still the champ for pure monitoring value.

Value & Pricing
Value is where the K240 Studio makes its strongest case. With a price that typically hovers around $50, it's competing in a bracket where corners are usually cut on sound first. The fact that it delivers a genuinely neutral, mixing-ready profile at this price is remarkable. We've seen prices for this model range wildly from $50 to an absurd $9,550 across vendors, so you'll want to stick with major retailers like Amazon or Best Buy to get the real deal. At fifty bucks, you're getting a tool that audio engineers have trusted for decades, and that's a steal.

Price History
詳細情報
Overview
The AKG K240 Studio is a bit of a legend in budget audio circles, and the numbers back up its reputation where it counts. Its social proof sits in the 89th percentile, meaning it's one of the most widely adopted and reviewed headphones in our database. With a 4.5-star average from over 12,000 ratings, people clearly find something to love here. The sound signature lands in the 66th percentile, which is solid for a headphone often found for around $50. It's a clear, neutral listen that's genuinely useful for mixing and monitoring without flattening the fun out of your music.
Common Questions
Q: Can I use these for gaming or calls?
You can, but you probably shouldn't. The mic performance is in the 20th percentile, which is one of the worst we've seen. Your teammates will not thank you. The semi-open design also means zero sound isolation, so every keyboard click and background noise will bleed through.
Q: Do I need a headphone amp to drive the 55Ω impedance?
Not necessarily. With a sensitivity of 104dB, most modern laptops and audio interfaces can drive them to a usable volume. However, a dedicated amp or a decent audio interface will give you more headroom and a slightly tighter low end, which is helpful for critical mixing.
Q: How much sound do these actually leak?
A lot. The semi-open back is a feature for accurate sound, not for privacy. Someone sitting next to you in a quiet room will definitely hear your music. They're designed for solo studio use, not for a library or an open-plan office.
Who Should Skip This
Anyone who needs a do-it-all headphone should look elsewhere. The mic is a disaster for calls, the sound leakage makes them a public nuisance, and the comfort score in the 34th percentile means they're not the best for all-day wear without breaks. If you need wireless connectivity, noise canceling, or any kind of sound isolation, the K240 Studio will disappoint you in every single one of those areas. This is a single-purpose tool for mixing and monitoring, and it's a bad fit for a generalist.
Verdict
The AKG K240 Studio is a purpose-built tool that has aged incredibly well. It's not trying to be your gym buddy or your noise-canceling travel companion. It's a wired, semi-open headphone designed to tell you the truth about your mix, and it does that job admirably for the price. The overwhelming user sentiment confirms that people who buy it for studio work are happy. Just don't expect it to be a great all-rounder for calls or commuting, because the numbers in those areas are frankly terrible. If you need a reliable, affordable set of cans for mixing, this is an easy recommendation.
