Transducer Planar Magnetic

The 7HZ Timeless are sleek in-ear monitors (IEMs) with a planar magnetic transducer advertised to improve audio clarity and detail. Thanks to this design, they have a very neutral sound profile with a fairly thumpy and punchy low-bass. Their mid-range is very flat and even, but their underemphasized treble veils vocals and lead instruments while sibilants like cymbals are dull. Unfortunately, while their circular aluminum bud casing helps them stand out from the crowd, this design is a bit bulky and can cause some fatigue over time. Also, the silicone ear tips are prone to ripping, so you need to handle them carefully.

Our Verdict

7.5 Neutral Sound

The 7HZ Timeless are good for neutral sound. Unlike most IEMs, they have a planar magnetic transducer, which can help tighten their bass response. As a result, they have a very neutral sound profile and can reproduce bass well, ensuring your mixes have adequate thump and punch. Their mid-range is also fairly flat, although their underemphasized treble veils vocals and lead instruments while sibilants like cymbals are dull. Unfortunately, due to their in-ear design, their passive soundstage seems closed-off, and sound is perceived as if coming from inside your head.

Pros
  • Well-built and decently comfortable.
  • Very consistent audio delivery.
Cons
  • Closed-off passive soundstage.
5.4 Commute/Travel

The 7HZ Timeless are disappointing for commute and travel. Although they're very portable and have a decently comfortable fit, they don't block out the low rumbles of bus and plane engines, which can be a bit annoying. On the upside, they feel well-built, and their hard carrying case can protect them from damage when you're on the go.

Pros
  • Well-built and decently comfortable.
Cons
  • Doesn't block out bass-range noise.
  • No mic.
6.5 Sports/Fitness

The 7HZ Timeless are okay for sports and fitness. They're decently comfortable and well-built. Since their audio cable hooks over your ear, they have a very stable fit that shouldn't move around during tough workouts. Although their cable is a snagging hazard, the cable can detach from the buds. That said, they lack an IP rating for water resistance, but this is to be expected from in-ear monitors.

Pros
  • Well-built and decently comfortable.
Cons
  • No IP rating.
5.4 Office

The 7HZ Timeless are disappointing for office use. Unfortunately, they don't have a mic, so you can't take calls. That said, they have a decently comfortable fit, don't leak much sound at high volumes, and can isolate you from ambient chatter. They're well-built, thanks to their aluminum bud casing and detachable braided audio cable.

Pros
  • Well-built and decently comfortable.
  • Can isolate you from ambient noise well.
Cons
  • No mic.
4.1 Wireless Gaming

The 7HZ Timeless are wired earbuds, and you can't use them wirelessly.

6.2 Wired Gaming

The 7HZ Timeless are mediocre for wired gaming. They don't have a mic, so you can't chat with teammates. However, if you don't need a mic, they have a neutral sound profile that ensures the accurate reproduction of dialogue and lead instruments. They also have a decently comfortable fit and are well-built.

Pros
  • Well-built and decently comfortable.
  • Very consistent audio delivery.
Cons
  • Closed-off passive soundstage.
  • No mic.

Style

The 7HZ Timeless have a circular earbud design. They're made from aluminum and have a textured circular finish. They have thick braided audio cables that are detachable, so you can swap them out if you prefer a different look. They only come in one color variation: 'Black'.

The 7HZ Timeless are decently comfortable in-ears. They don't put too much pressure on your ears, and they come with quite a few differently sized ear tips to help you get the best fit. Unfortunately, the aluminum earbud casing is a bit bulky, and depending on the shape of your ears, it can cause some fatigue.

These earbuds have outstanding portability. You can easily fit them into most bags or pockets without a problem. That said, while they come with a sleek carrying case to help protect the buds when you're on the go, it can add a bit of bulkiness.

The 7HZ Timeless have a good carrying case. It's made of brushed aluminum, which feels solid and sturdy. There's a magnet to help keep the lid closed, and the case is lined with a velour-like fabric to protect the buds. However, the fabric lining has started to peel away from the case. The case itself is a bit heavy and bulky too, which can make it hard to fit into your pockets.

Build Quality

The 7HZ Timeless are well-built. Their aluminum bud casing and braided cable feel sturdy. They also come with extra metal filters, which are handy if you need to replace yours due to ear wax build-up. That said, the silicone ear tips are prone to ripping or forming holes. The fabric lining in the carrying case can also detach over time. They lack an IP rating for water resistance, although this is to be expected from IEMs.

Stability

These buds have a very stable in-ear fit. The audio cable hooks over your ear, so even when you're on the go, they shouldn't fall out. Even though the audio cable can snag on something, they use MMCX connectors to attach to the earbuds, so they can disconnect when pulled.

The 7HZ Timeless have a very neutral sound profile versatile enough for most kinds of audio genres. Although they have a slightly underemphasized low-bass, they still deliver a bit more thump and rumble than the MOONDROP KATO. That said, a dip in the treble range veils vocals and lead instruments while sibilants like cymbals are dull.

The 7HZ Timeless' mid accuracy is excellent. The range is fairly flat, and although a dip in the mid-mid nudges vocals and lead instruments to the back of your mix, they're still clear and detailed in your mixes.

The 7HZ Timeless have decent treble accuracy. It's underemphasized across the range, so vocals and lead instruments are a bit veiled. Sibilants like cymbals are also a bit dull.

The peaks and dips performance is great. There's a small peak in the high-bass, which adds boom to mixes while a dip in the mid-mids nudges vocals and lead instruments to the back of your mix. Another peak in the high-mids brightens vocals and instruments, but a dip in the low-treble veils their upper harmonics. A very uneven mid-treble indicates alternatingly dull and piercing sibilants like cymbals.

The 7HZ Timeless' imaging performance is excellent. The weighted group delay response falls below the audibility threshold, resulting in tight bass and transparent treble reproduction. The L/R drivers are well-matched in amplitude, frequency, and phase response. It's important for the accurate placement and localization of objects like voices in the stereo image. Although there's a small peak in the phase response's mid-mid, it's difficult to hear with real-life content. That said, imaging can vary between units and can indicate a manufacturer's quality control and ergonomics. Planar magnetic drivers are also prone to more variance between units compared to dynamic driver headphones like the MOONDROP KATO due to the complexity of this kind of driver.

These headphones have a bad passive soundstage performance, which is to be expected from IEMs. One of the large factors in creating an out-of-head and immersive passive soundstage is that sound resonances interact with your outer ear. Since IEMs bypass your outer ear by design, their soundstage is perceived as closed-off and as if coming from inside your head, rather than from speakers placed in the room around you. It also doesn't seem as open or spacious as headphones with an open-back design.

The 7HZ Timeless' noise isolation performance is sub-par. Like the MOONDROP Aria, they have an in-ear fit, and struggle to isolate you from the low rumble of bus engines. However, if you're working in a noisy office, the buds do a better job of blocking out ambient chatter as well as humming AC units.

The 7HZ Timeless' leakage performance is excellent. Most of their leakage is concentrated in the treble range, so audio that escapes sounds thin. However, if you're listening to audio at high volumes in a moderately noisy place like a busy office, you shouldn't bother others around you.

Differences Between Sizes And Variants

The 7HZ Timeless IEM come in one color variation: Black. You can also purchase them with either a 3.5 mm, 4.4 mm, or 2.5 mm cable termination. If you come across another variant, please let us know in the discussions, and we'll update our review.

Compared To Other Headphones

The 7HZ Timeless are in-ear monitors (IEMs) with planar magnetic drivers, which is uncommon in this size of headphones. This design helps tighten their bass response, and when compared to audiophile headphones with a dynamic transducer like the MOONDROP KATO and Etymotic ER4XR, they produce thump and rumble more accurately. They have a very neutral sound profile and a well-built design with an aluminum earbud design. However, unlike other IEMs with double flange ear tips like the Shure SE215, they have sub-par noise isolation, which can be frustrating as they won't block out much sound during a noisy live set.

Check out our recommendations for the best audiophile headphones, the best wired headphones, and the best earbuds and in-ear headphones.

MOONDROP KATO

The MOONDROP KATO and the 7HZ Timeless have different strengths. The MOONDROP are in-ear monitors (IEMs) with a dynamic transducer that are more comfortable and have a better build quality. Their treble range is flatter and more accurate, and they come with two pairs of nozzles made in different materials to help you customize their sound. However, the 7HZ are planar magnetic IEMs that deliver audio more consistently, have much better bass accuracy, and have a flatter mid-range. They can also block out more background noise, although their performance in this regard is still sub-par.

MOONDROP Aria

Depending on your preferences, you may enjoy either the MOONDROP Aria or the 7HZ Timeless for neutral sound. While both headphones are well-built and have very neutral sound profiles, the MOONDROP are more comfortable and come with a better hard case to protect your headphones on the go. However, the 7HZ have a more accurate treble range.

Apple AirPods Pro Truly Wireless

The Apple AirPods Pro Truly Wireless are more versatile headphones than the 7HZ Timeless. The Apple are wireless headphones that are more comfortable, better-built, and have active noise cancelling to help block out a great amount of noise around you. They also have an integrated mic, although it offers a sub-par overall performance, and they have an H1 chip for seamless pairing with your Apple devices. However, the 7HZ are wired headphones with a more stable fit.

Beyerdynamic DT 770 PRO

The Beyerdynamic DT 770 PRO are better audiophile headphones than the 7HZ Timeless. If you prefer over-ears, the Beyerdynamic have a more comfortable fit, a better build quality, and a more neutral sound profile. Their passive soundstage also feels more out-of-head and wide. However, the 7HZ are wired in-ears that are more stable and have significantly more consistent audio delivery. They also leak less audio at high volumes.

1More Triple Driver

The 7HZ Timeless are better in-ears for neutral sound than the 1More Triple Driver. While both headphones are decently comfortable, the 7HZ are better-built, have a more stable fit, and their sound profile is more neutral. However, if you're looking for more versatile in-ears, the 1More have an in-line mic and controls so that you can take calls on the go.

Etymotic ER4XR

The 7HZ Timeless are better IEMs than the Etymotic ER4XR. The 7HZ are planar-magnetic headphones that are more comfortable and have a more neutral sound profile, which some users may prefer. However, the Etymotic are better-built and can block out more background noise.

Sennheiser HD 600

The Sennheiser HD 600 are better headphones for neutral sound than the 7HZ Timeless. While both headphones are decently comfortable and well-built, the Sennheiser are open-back over-ear headphones with a much more accurate treble response and a more open and spacious passive soundstage. However, if you prefer in-ear monitors (IEMs), the 7HZ have a planar magnetic transducer, which helps them reproduce a more thumpy low-bass. They can also block out more background noise and leak less audio at high volumes.

Shure SE215

The 7HZ Timeless are better in-ear monitors (IEMs) than the Shure SE215. The 7HZ have a planar magnetic transducer design that helps them reproduce a more thumpy and punchy bass. Overall, they have a more neutral sound profile, which some users may prefer, and they're more comfortable. That said, the Shure have a dynamic transducer design, are better-built, and can block out more background noise as they have a double flange ear tip design.
