According to Audio-Technica, whose inexpensive and decidedly cubist ATH-SQ1TW earbuds still hold a dear place in our hearts – and a coveted spot in our best budget earbuds buying guide – the Japanese audio expert's been on "a 15-year quest for super deep bass" and the new ATH-CKS30TW+ earbuds are the result. With a frequency response of 5Hz to 20,000Hz these earbuds go low, too. For clarity, humans can only hear from 20Hz up; anything lower than that we feel as vibrations in our bodies.
The ATH-CKS30TW+ buds are built around proprietary 9mm drivers with "acoustic ducts" to deliver tight low frequencies, and you can tweak the sound via AT's app where you'll find a new 'Bass Boost – Deep' option to pushes those bass frequencies further. There are also four preset listening modes for beats, dynamics, vocals and clarity, and there's active noise cancellation with hear-through and talk-through functions.
