About the IEM

  • Somewhat odd design that I wouldn’t really like wearing in public because of the big disk that protrudes out of the ear
  • Excellent fit, that quite surprised me given the design
  • Great overall package with a big selection of tips and a good-feeling cable
  • Seems to have some QC problems according to other users, everything was fine with my unit

🥈Great accessory package and good fit, somewhat hindered by a unsightly design and QC problems

Sound Impressions

  • Excellent crisp and dynamic bass
  • Treble can be piercing at some points
  • Tends to loose some detail and resolution in the treble region
  • More suitable for male than female vocals → shown quite well in “Without a Parachute by Anna Rosinelli”
  • Midbass can sometimes drown out part of the vocals and move them to the background of a track
  • Vocals can further give a “metallic” impression, especially female vocals
  • Average stage and imaging is too “central”
  • Outstanding details and resolutions, nearly unmatched at that price point

🥈Decent sounding IEM with a fun and entertaining tuning that excels with outstanding details and resolution

Song Impressions

SongImpressions
White Dress – Lana del Rey Vocals unpleasant (-> Treble)
Altes Fieber (ohne Strom) – Die Toten HosenVocals a tad too much in the background, live audience almost not hearable, solid live stage imitation
Another Love – Tom OdellBass suprisingly a litte lacking, Vocals get good representation and feel intimate enough, instruments tightly clustered
Exile – Taylor SwiftJustin Vernon’s vocals sound just amazing and powerful, while Taylor’s voice is just bit frayed, soundstage too close

Comparisons

Shuoer S12: The elephant in the room

When reviewing the 7Hz Timeless, there’s one big elephant in the room: The Shuoer S12, another well-received planar IEM with a similar tuning to the Timeless. While I haven’t yet listened to the S12, most people that have heard both, tend to prefer the S12, even if it’s just because of the about $60 lower price. When you’re looking to buying the Timeless, at least keep the existence of the S12 in mind.

SeeAudio Yume:Midnight

The Yume:Midnight are one of the benchmark IEMs at around $200 and therefore a logical comparison to the Timeless.

Yume:Midnight

  • More enjoyable treble
  • Better female vocals
  • Stage is wider and imaging more exact

Conclusions

The 7Hz Timeless are quite the success. Not only are the Timeless the first Planar IEMs that are actually good and enjoyable (sorry Tin P1…), they are just good IEMs.

7Hz Timeless with Cable

They excel especially with technicalities that are almost unmatched at around $200. For IEMs that are as detailed and as resolving, you’d almost have to go to the about $100 more expensive Moondrop Blessing 2 (Dusk).

The mid bass is the one thing that’s a somewhat big downside for my personal preference. It tends to overpower and overshadow the mids and especially the vocals. Combined with a peaky treble performance, vocals aren’t necessarily the Timeless’ strength.
