In a sort of Nigel Tufnel/David St. Hubbins fire/ice schism my learned colleagues Alberto and Durwood have offered completely different takes on the 7Hz Timeless, with Alberto finding them lacking microdetail and unrefined in the treble, while Durwood praised their transparency and resolution.
I lean closer to Durwood on this one—with sufficient power, they epitomize the best qualities of planars—speedy transients, tight (if lean-textured) bass, energetic big-sounding midrange and highly resolving high end which captures the little nuances of acoustic guitars as well as anything I’ve heard at this price point.
I do agree with Alberto that some midbass oomph is missing and that they’re prone to a slight shoutiness/steeliness on some higher frequencies—saxes and female vox can occasionally sound overbright.
The 7Hz Timeless are also a poor match for mobile phones or less powerful sources. However, feed ‘em right and they are damn good and well worth the $200.
