Features
- The 7Hz Legacy7Hz made a global wave in the past with several of its most popular models. IEMs such as the Salnotes Zero, Dioko, and Timeless gathered massive popularity due to their amazing sound-to-value performance. 7Hz has proven itself to the worldwide audience as a trusted manufacturer of high-performance IEMs, and will continue its legacy with better innovations and stronger community engagement.
- Upgraded 14.5mm Planar Magnetic Driver7HZ Timeless II IEM features the latest R&D from our team, with a bigger 14.5mm diaphragm, which is the worlds first use of dual-sided coated diaphragm in the IEM. Our in-house coating process layers microns-thick even surface application of specialized silver alloy, which significantly increases the surface tension of the diaphragm. The new diaphragm, driven by a strong dual-sided N52 magnet array, is extremely responsive, taking the planar diaphragm concept to a whole new level.
- Tunable NozzleThe Timeless II in ear monitor headphone also features a new tunable nozzle concept, so that the user can adjust their sound preference. This idea is derived from the concept of speaker phase plugs, which allows the extension and adjustment of ultra-high frequencies. We have designed two special nozzle shapes, with two materials for precise tuning of the IEM. The standard copper nozzle, stainless steel cone nozzle, and copper cone nozzle all provide unique and effective ways to adjust the Timeless IIs sound to fit your music library.
- Newly Designed Driver EnclosureThe Timeless IIs new planar drivers required a redesign of the acoustic driver enclosure to provide a balanced and natural tuning. With a 7-layer design featuring a double acoustic rear venting system and a more secure locking system, the driver can be more precisely tuned, as well as be more durable and stable. The diaphragm was also directly mounted onto its support structures to provide more rigidity and tighter surface tension within the driver.
- Updated IEM CableThe Timeless II wired earbud comes standard with our new upgraded cable. The cable is a 4-core ultra pure 7N single-crystal copper cable, with detachable 2pin connectors. This configuration was specifically chosen to provide additional body and warmth to the Timeless IIs new driver, while enhancing the transparency and details. With the detachable cable design, the user can change the cable to fit their preference, as well as extend the longevity of their IEM.

Linsoul 7Hz Timeless II feature large 14.5mm planar driver. Linsoul does not manufacture IEMs themselves but operates primarily as a distributor and retailer of audio products from Chinese HiFi brands such as ThieAudio, Kiwi Ears, ZiiGaat, FiiO, KZ, and Tin HiFi. They buy complete IEMs from these manufacturers and resell them internationally, with a focus on Chinese Hi-Fi gear. Additionally, Linsoul offers customization services, such as custom-molded shells or faceplates for existing IEMs, which involves minor assembly or modification using parts from those manufacturers rather than full in-house production. Some brands they distribute, like ZiiGaat and ThieAudio, are considered "house brands" closely affiliated with Linsoul, but the actual manufacturing is handled by specialized factories in China. The construction and the cable seems solid. The cable is not as thick as on some other top IEMs, but it's decent. Honestly, I think they sound better than their price suggests—they outperform some more expensive IEMs, and I definitely expected less. However, the sound is quite harsh, and I can already tell it will be fatiguing at high volumes. This is my biggest issue with them. The soundstage isn’t as wide as on the Fiio FH9 ($600), although it's definitely very good for the price. Separation of instruments is also very good for the price. And the fit is comfortable to my ears. Some people praise their sub bass, but I didn't notice anything super powerful. The bass is present, but not especially amplified to my ear. Maybe some equalizer adjustments can make the sound a bit milder, in which case they'd be an excellent option for the price. I've experienced headphones that cost thousands of dollars, so my standards are extremely high. That's why I can't say I'm completely happy with this Linsoul 7Hz Timeless II model. Still, I can see them making a lot of people happy—especially those who aren’t as obsessive about sound quality as I am. Overall, the quality-to-price ratio is great here, and in my experience, these are definitely among the best IEMs for their price. If the manufacturer fixed the harshness, they’d be worth much more and could easily compete with $400+ IEMs.

1st, what nozzle is my favorite. The stock gold flat one. This lil review is talking about it with that one. The other 3 just sound weird but the gold bullet one is my 2nd favorite nozzle followed by the flat silver then silver bullet one. Ok so size/shape fits feels fine. Build quality is premium. I'm using large yellow kb 07 eartips and stock cable. It's a analytical very mild V shape and very fast driver. Light boost in bass mids dipped a little and treble really detailed and airy. Positioning is very good soundstage is good. Timeless ii vs S12 Pro. It's definitely faster than the s12 pro and positioning of instruments is more accurate than the s12 but the s12 pro soundstage feels bigger and lil more organic, and treble is smoother and detailed airy as well. S12 pro is really good too but the timeless is more accurate. They both have pros and cons and honestly they're tied neither are exactly better than one or the other in my opinion. Build quality both really good but the timeless is a lil more fancy cause of the face plate design. I have a few more pure planar iems but I'm comparing the closest one that's another goat planar. Timeless ii is worth the money excellent build nice eartips and good quality cable. Plus you have tuning options that you can mod easy by buying tuning foams and experiment with them. 10/10 iem. It's a iem I wouldn't recommend as your 1st iem. But if you have a growing collection of iems definitely would recommend them.

The Timeless II is a worthy predecessor to the original timeless. The planar driver is similar to the widely-appraised kiwi ears aether with the same N52 magnet setup. However, the build quality is superior here with the ergonomics and metal shell. As a gamer, I prioritize technicalities when picking out IEMs and headphones. These IEMs are more than enough for competitive gaming where imaging such as directional audio ques and distance perception along the "soundstage" are most important. The Height, width, and depth of the soundstage are above average for planars and especially IEMs in general. I preferred using the flat silver nozzle over the flat golden nozzle for gaming. The bass quality is phenomenal and I've come to prefer it over what your average dynamic driver can produce. It's very fast and tight as all planars should be, though it has a surprising amount of thump and rumble when music or movies call for it. One of the biggest surprises for me is the ability to make out precise imaging of bass with this iem. I have never heard anything like it. By that, I mean the bass coming from a bass guitar might come from above/in front of you while the bass of kick drums are coming from behind you as they are perceivably separated by the rest of the instruments and the vocalist (as long as the audio mixing for the song was done properly and the producer knows what they're doing). As a side note, you will quickly learn the difference between good and sloppy music production. The lower midrange is clear and void of mid bass interference. The upper midrange is quite impressive for planars with how natural it sounds. Never metallic, never shouty. This is what gets effected most by the various nozzles that come in the box. Compared to the gold nozzle, the silver nozzle lowers the 2khz frequencies which makes the treble region sound more pronounced. Detail retrieval is unaffected by swapping nozzles. The rounded, tipped nozzles need to be used with the blue ear tips to really experience what they can do. You'll notice the holes on the sides of those nozzles get compressed by the walls of the inner ear tip tube, which causes the sound waves to push out through the tip of the nozzle. This creates a completely different soundstage and frequency response shift. It will make everything sound smoother yet more spacious. I prefer these blue ear tips/ rounded nozzles for jazz, hip hop, and movies. Without the blue ear tips being used along with those rounded nozzles, there is very little change in sound besides a minor shift towards a vocal-forward sound. Overall, this is a must try IEM. If you've been contemplating trying a planar or IEMs in general, this could be the last one you'll ever need. It's a real all-rounder but not in a way that makes it a "jack of all trades but master of none". With the various nozzles and different ear tips, it's more of a Swiss army knife.
