The first version of AKG’s K240 model was released 40 years ago this year, and its successors have built a substantial following over the decades, both for use in studios and for home listening.
The K240 mkII is a semi-open design, which allows the drivers to produce a more accurate, less coloured sound than an equivalent closed-back model. The result is a pair of headphones that produce remarkably impressive sound for their price point. The downside is, of course, that sounds from the headphones spill out to the surrounding area and ambient noise can still be heard, but if you’re working in a relatively quiet environment then the sonic benefits are noticeable. (It probably goes without saying that the K240s aren’t suitable for DJing or for working on music on the go.)
In addition to their sound quality, the K240s also deserve praise for the comfortable fit of their circum-aural earpieces. These are headphones most people will find comfortable enough to wear for extended periods.
But perhaps the best part of all is the price. At an RRP of £109, they’re great value for money, but it’s an even more attractive deal when you bear in mind most retailers will be happy to knock 25% off that recommended price. If you’re on a tight budget, the slightly cheaper K240 Studio model sounds identical, but it’s supplied without the spare cable and earpads you’ll find bundled with the mkII.
The K240 mkII is an incredibly affordable open-backed model with impressive sound quality for the money. If you need the isolation of a closed-back design then they won’t be suitable, but if you can get away without it you’ll find that these are some of the best affordable headphones on the market.
