Intro

Disclaimer: The 7Hz Timeless was purchased with my own money for my personal use and this review is written of my own accord. All opinions here are my own. If you find yourself interested in a pair, you can check them out here. The cable above is the XINHS 8-core Silver Cable (review) from my personal collection.

I’m incredibly late to reviewing this pair but I really took my time with this one. Spoiler alert: I enjoyed my time with the 7Hz Timeless and I wanted to minimize the Hype Train Effect.

Accessories

The Timeless comes with quite a selection of silicon tips and some foam tips. Honestly, they didn’t really appeal to me so I tip rolled a few third-party tips and after trying on the Azla SednaEarfit Tips, I never looked back. An extra set of nozzle filters are also included.

The bundled case has a full metal construction with a fabric lining on the inside, it’s a little small considering the Timeless is on the larger side and I didn’t really like the idea of the metal construction as it’s really heavy and can scratch other things in your bag.

The stock MMCX cable can come in the termination of your choice (2.5mm/4.4mm balanced or 3.5mm single-ended).

Build Quality and Fit

To get the build quality out of the way, I think they are handsomely built, with all-metal construction for the buds and a matte black finish. My only concern is the MMCX connection as usual, but I don’t think you would have any issues as long as you connect/disconnect them properly.

However, the fit is a little out of the ordinary. There is a huge circular disk acting as a faceplate, giving the IEM an iconic look. It’s good to note that the disk is only on the exterior and doesn’t touch the ear, hence I didn’t have any discomfort, though YMMV. The nozzle isn’t too long, but the stiffer and slightly longer nozzle on the AZLA SednaEarfit tips helped give a tight seal.

Bass

My biggest gripe with the 7Hz Timeless is probably the bass. The bass seems a little mismatched with the rest of the sound in terms of speed. The bass comes off a tad bit too strong and heavy-footed, especially when I first tried it on. It slowly became more enjoyable the more I listened to it (brain burn-in?) Perhaps it provides a slight relief and respite to the crystal-clear attack of the upper mids and treble, making the 7Hz a much more enjoyable Planar IEM as compared to others like the TinHiFi P1.

The bass extends very deep and has a satisfying Subbass rumble that shines on EDM tracks (The Fat Rat Xenogenesis). This plays well with the clarity of the upper mids and gives a very nice layering effect on the sound.

Mids

The upper mids have a very crisp response. The tonality of the mids are very impressive, and the Timeless strikes a good middle ground between resolution and musicality. Exceptional performance for its price bracket. Vocals shine well with a soft edge to them so they don’t come across as overly clinical. Plugging the Timeless into a better source makes the mids a bit more expansive and gives it more space to shine, overcoming the “recessed” feeling. Timbre is also very pleasant.

Treble

Tre

Treble is very speedy and have a very good resolution. Cymbal crashes come across a little dry without any splash, but with a very sharp attack, and I can see why some people may not be a fan of this characteristic. However, I appreciated how it made the percussions punchier and crisper, and I really enjoy the nuance and layers that it adds to the sound. The Timeless can handle complicated and congested music with ease. However, on some songs, it can get a little too spicy, and potentially fatiguing for long listening sessions.

Overall

I used the 7Hz Timeless predominantly balanced on my desktop setup as I didn’t really fancy it as a portable pair. I found my setup gave it a very nice breadth and height, and it performed well enough in terms of staging for an IEM. The sound signature is rather balanced with a boost of warmth in the bass. However, it isn’t anything over the top to send this into basshead category.

I won’t attempt to do a full comparison to the TinHiFi P1 since it has been a while, but one thing I can say for sure is that the tuning on the Timeless is much more palatable and less fatiguing than the P1.

Conclusion

The Timeless performs excellently and fulfils its niche as a planar IEM extremely well. It plays to its strengths perfectly. That said, the Timeless still has its “flaws” or certain caveats that not everyone would be a fan of, like the fit, and tuning, which at the end of the day, is a personal preference. From my perspective, the Timeless suits my tastes and library very well and I absolutely don’t regret a single cent I spent on it.

The Timeless managed to deliver a stellar resolution with a pleasant tuning, earning its place in my personal collection. Is there room for improvement for future planar IEMs? Yes but I foresee the Timeless sticking around for quite some time.
