New Head-Fier
Pros: Bright and Detailed Sound, Premium Build Quality, Light and Comfortable, Design
Cons: Lack of Bass, High's can be a bit piercing
The UiiSii HM7 offers a bright sound characterized by upper mid's and high's. The bass could be stronger. Premium build quality makes the UiiSii HM7 look a lot more expensive! The light weight and small design makes them very comfortable!

The UiiSii HM7 is a popular model of UiiSii. This pair of earphones is a popular model, which made me curious about them. At the first eye they the build quality look great for the money you pay for it. Will the sound also be? Time to check them out.

Sound
The first impression I’ve got when I started listening to the UiiSii HM7, is that these earphones produce a bright sound. There is a strong emphasizes on the higher midrange/lower treble. The bass is accurate but thin. I would prefer to have a stronger bass present. The midrange and accurate and detailed. Vocals in music and clear and with the stronger upper mid’s, they get this clear sounding of the vocals. The high’s of the UiiSii HM7 are present, and making music sound crispy. They can be a bit harsh on the ears, since they are a bit edgy. In short, the focus of the UiiSii HM7 are on the upper mid’s and high’s, which results into bright music. I accuracy of the bass is and punchy, but unfortunately thin. The sound is missing a bit body.

Design & Build Quality
The design of the UiiSii HM7 are looking really good! The earbuds are small and created of some kind of aluminium material, which provides them a nice premium look. The other components, the headphone jack and the microphone, are created of the same aluminium material, which looks really good. The build quality is overall really high, something you wouldn’t expect for earphones costing about $8. The outside of the cables is created of stiff material, something I dislike, because this may cause the cables to pull out the earphones.

Comfort
As mentioned, the earbuds are small, which makes them also really small. In combination with the comfortable eartips, the UiiSii HM7 are very comfortable! You can barely feel them into your ears. The sound can be a sharp on the ears if you are sensitive for high frequencies.

Conclusion
The sound quality and build quality the UiiSii HM7 delivers for this price, makes them absolutely a great deal. Most of the earphones in the price range are a trade-off in sound, design or build quality. The UiiSii HM7 is able to deliver a detailed bright sound, unfortunately the bass is a bit lacking, which provides the sound less body. The build quality is premium and of high standards, as well as the design looks good. If you are looking for bright sound, premium quality and comfort for a low price, I absolutely recommend these! If you are more a bass-head, I recommend to check out earphones as the Rock Zircon or KZ Ate.

100+ Head-Fier
Pros: Comfort and Isolation
- Channel Separation and Imaging
- Mids and Highs
- Costs $5.50
Cons: Bass sounds bloated and can bleed into lower mids
- You can't resist from buying this one
Disclaimer: This review unit was purchased by me with my own moolah ($5.59 from Gearbest). This is my unbiased opinion, based on my listening preference.

Packaging:
The HM7 comes is a very generic 'Chi-fi' packaging - a paper box with a plastic display window. The window shows one side of the HM7 along with the microphone controller and 3.5mm jack. The way the cable is bent near the microphone is not great and it is difficult to remove the bend from the cable.

There are 3 wide-bore tips included with this earphone - the medium sized one is pre-fitted. The quality of the tips is good unlike KZ which sells in similar price point.

Build and Fit:
The HM7 has a nice aluminum shell and it looks and feels premium. Even the microphone controller has a great build and the single button provides nice tactile feedback. The cable is coated with silicon (not the sticky type) and is perfumed. It should go the distance.

The fit is super-comfortable. These can be worn for a long time without any issues.

Review of the Sound Signature:

Setup for the review
Mine is a poor man's setup :ksc75smile: - For the sake of this review and for my usual listening sessions, I pair my earphones with my LG G6 (with ES9218P DAC from ESS) or with my Asus laptop. I don't use any sort of equalization unless explicitly mentioned. I have a few free FLAC samples, else it is primarily Google Play Music at highest quality settings. So in a nutshell, I'm a regular bloke who likes music.
Edit: The review was updated based on my listening session with these using a Tidal HiFi subscription.

These earphones sound great out of the box. No burn-in is required to enjoy these earphones, which is exactly how I prefer my earphones.

The best part about these earphones is the Higher Frequencies. The Highs are bright and energetic and pack some nice details. I fell in love with Muse's Uprising and Panic attack on the HM7. Max Roach's Lonesome Lover is a nice song for testing the treble response and the HM7 fairs quite well. Micro details are hard to hear on Daft Punk's Get Lucky, but then at this price, it does not matter.

The Mids are nice and forward. The imaging is great on the HM7s and the mids are nicely centered and packed with energy. Alma's voice on Felix Jaehn's Bonfire sounds quite energetic. Madness by Muse and Billie Jean by MJ highlights the channel separation and imaging further. There is some bass bleed into the lower mids and the mids are not airy due to this, especially on bassy tracks. Vocals have a good texture on acoustic tracks.

Bass is quick on attack and decay and has acceptable levels of texture - the beats on Das Spiegel are quite fast. The fast Bass in combination with energetic highs makes Daft Punk's Get Lucky an interesting listen on the HM7. The bass is emphasised around the 100Hz to 250Hz region is not emphasised too much. The bass, while ample in quantity can sound bloated on many taskst. The bass, equal in the mid and sub range, hish hard and this is quite evident on Doin' it Right by Daft Punk. That said, bass-heads will love this one.

So how does it perform on complex tracks?

I threw Radiohead's National Anthem (Kid A) at the HM7 and it handled the cacophony at the 3 minute mark quite well. I was still able to distinguish the various instruments. Most budget single DD IEMs just blurt out a mish-mash of sounds on this song.

The sound-stage is not very wide - everything is just in and around your head. But it should not be a problem for most modern tracks.

Other significant points
  • The HM7s are rated 16 ohm, but the sensitivity is quite low at 90dB and hence they need higher volume than usual to drive them.
  • The micro-phonics from the cable are manageable; a collar clip should be able to control it
  • The single-button control pauses the track on a single press and advances to the next track on double press. But it does not go to previous track on triple press, as specified.
Conclusion
The UiiSii HM7 is an amazing earphone for $5.59 and it is a must buy for anyone who has just started exploring the various sound-signatures of earphones.

This is the best value for money earphones one can ever buy, in my opinion

This is the 2nd earphone I bought purely from excellent review by Igor Eisberg of Audiobudget website. I bought it from Aliexpress for 8USD. They are still on transit somewhere. Today I have a chance to make a window shopping and tried out few earphones in my local electronic mall in Low Yat Plaza, Kuala Lumpur. They are selling mainly a lower end earphone and some midrange earphone that cost up to about 120USD. Fairly affordable I must say. The most expensive that I tried was Denon C100 Urban Raver, about 90USD RRP. Some excellent low end earphone like Philips SHE3595 and SHE 3905. They also have Logitech UE400 ,about 30USD. Sennheiser CX300II is selling for 55USD.

Suddenly I saw this UiiSii HM7 at one of the shop selling at about 6.5USD. Unbelievable, if I haven't ordered yet from Aliexpress I will definitely buy it immediately. The test earphone was pink but they also have both grey and gold version. What I noticed first was the housing itself. It made of metal which I didn't expect from a very cheap earphone like this. It shaped like a 3/4 globe or "orb like" as described by Mr Igor. They are very small about 1x1x1.5cm with nozzle. It almost feels weightless in my ear and sit quite firmly with it's stock clear silicone tip. This kind of ultra lightweight design make it very comfortable for long listening, but can be easily pulled out due to shallow fitting.
The 2nd feature that I noticed was the soft clear cable which clearly show of the inner copper cable. It may looks like the one on KZ series earphone cable but it has better quality material and not sticky. I don't exactly know what material they use but it does feels like a silicone. The cable is thicker than KZ cable probably about 2mm diameter before the Y splitter. The Y splitter and earphone jack are both made of cylinder shape metal and the jack itself is straight type. There is no chin slider but I will no complaint because it is not really necessary due to extreme lightweightness of the housing. There is single button remote and mic on right cord after Y-splitter. It fully functional as music remote for start stop and double click forward. Not having chance to check the mic fuction. Overall the built quality are excellent and the material used make it actually feels more expensive that the RRP. Thumbs up UiiSii team, whoever they are.

Sound quality;
First impression ; this one sounds very aggressive but fun. Everything are there. The tight and thumping bass, clear vocal, sparklingly bright treble without any sibilance. Details are abundance but not as details as sony XBA10 or EX650. The closest earphone that has this kind of sound signature is Jvc-ha-fxt90. Yes you read it right. It almost sounds like the mighty FXT90. All for 6.5USD. Excellent price to sound ratio? This is totally beyond that. As if they have managed to squeeze in both FXT90 driver into such tiny housing. I am not sure you want to believe e it or not but for the whole day of trying out earphone in Low Yat Plaza, this UiiSii HM7 has managed to beat all the above mentioned earphone including my own earphone that I brought together today, the king of sub 20 himself, Boarseman CX98. Yes in pure sound quality I have to rate this HM7 higher than CX98, Denon C100, both Philips, UE400 and CX300II.

Comparison with CX98;
As a reigning king of sub 20, the CX98 has better built quality and accessories. The twisted cable with glossy plastic coating will likely last longer than the soft silicone coated cable of HM7. Sound quality wise, no competition at all, HM7 has better bass, better vocal and the sparkling bright treble is smooth and sibilance free. I never expected this since the price is 3 times higher with CX98. Of course with 20USD CX98 has better package and built quality, not to mention it looks better than HM7.

Comparison with Denon C100 Urban Raver;
This one has different sound signature. Really tight and thumpin bass but with recessed vocal and treble. In another word almost L-shaped sound signature almost similar to my Pioneer SE-CL541. Very good for bass heavy music but not really suitable for vocal or treble heavy music. In that sense the aggressively balanced HM7 is suitable for most music and sounds very pleasant to my ear. C100 as expected has better built quality. It has remote with volume button which not working with my HTC Desire 820s Android phone. Probably it work for IPhone or maybe I have to install apps before it can work.

Conclusion ;
My journey through budget oriented earphone has made me found the unexpected but pleasant suprise like this HM7 and CX98. Both sound particularly excellent no matter what music I am listening to. If you prefer something extremely cheap with maximum sound quality possible, this is it. Probably nothing can beat it in pure sound quality within sub 20 price range. At least until I got my Rock Zircon which is also on transit. Currently on Audiobudget Rock Zircon has still manage to stay on top according to Mr Igor. Just wait and see how is Rock Zircon performance against 2 mighty sub 20 champion the CX98 a d HM7. Is it better than FXT90? Close but no cigars. So the quest will still continue.

Thanks. How about comparing the isolation to the marshmallow? Also, if you don't mind, could you give me a visual idea on how much noise can it remove? For example, for the noise of the lawn mowers, compared to jvc and kz ate?

JVC Marshmallow? Don't have one. How much noise removed totally depends on what tip is used. Generally it will not block noise from loud source like lawn mower or motorcycle, but good enough to block noise from people talking at normal voice. A good seal with silicone tip will give best isolation, foam tip not so.

If you don't mind, could you please tell me, how does the isolation rate compare to etymotics products?
