5 source(s) feeding this product's score.
Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
8:39The reviewer finds the AKG K812 to be a comfortable, well-built, and musically warm-sounding headphone with good bass and midrange balance, but criticizes its ragged treble response, which causes harshness and reduced resolution in energetic music. At $1,500, the reviewer cannot recommend it for audio professionals due to these treble issues, though it may suit listeners of small acoustic ensembles.
12:32The reviewer finds the AKG K812 to be a disappointing flagship, with a bright and harsh treble that lacks resolution, and a midrange that is not warm. While the bass extends well and the comfort and imaging are good, the overall sound quality does not justify the high price, and the reviewer suggests cheaper AKG models like the K712 are better choices.
6:50The reviewer borrowed a friend's AKG K812 for two days and was pleasantly surprised by its sound quality, praising its open, spacious soundstage, detailed treble, and pleasing vocal presentation, especially for female voices. However, they note the build feels fragile due to thin plastic parts, the single-ended cable limits balanced use, and it requires a good amplifier to perform well. Overall, they consider it a great flagship headphone, though they acknowledge it may lack bass impact and momentum for some genres compared to rivals.
6:14The reviewer bought the AKG K812 after AKG declined to send a sample, and after extensive burn-in and listening tests, they conclude the headphones are not the best in the world, especially when compared to far more expensive models. They place the K812 in the 'Titanic area of the Reds' on their new rating scale, implying it is a poor value at its $1,600 price point, which they consider the bare minimum for audiophile quality.
