Radius HP-TWF21 “W N°2” aka “DDM 2” Review

ddm2 main Radius HP TWF21 “W N°2” aka “DDM 2” ReviewRadius Co. Ltd. are from Japan, but unlike fellow countrymen such as Audio Technica or Denon, Radius mostly relies on rebranding Chinese OEM in-ear phones rather than creating original designs. Most of their products are found in the lower price segment, usually competing with fashion brands such as Skullcandy or JBuds.

This however changed when Radius introduced the HP-TWF11 “DDM” phone some time ago. They were priced at around $200 and featured a seldom seen construction that uses two dynamic drivers; a big one for bass and midrange next to the ear and a smaller one for treble behind it – hence the “DDM” nickname that stands for “Dual Driver Matrix”. While these DDM couldn’t quite compete with top-tier dynamic driver IEMs such as the JVC FX700 or Sennheiser IE8, they pulled off a gigantic in-your-face bass while still retaining some very nice stereo imaging, timbre, and good dynamic range.

Now Radius revised their DDM concept and released the HP-TWF21 “W N°2”. Compared to the old DDM, the new DDM2 (as I call them) have an infinitely better form factor, somewhat more tamed bass quantity, better clarity… and of course a somewhat higher price tag than the old ones.
