Pros: Sound Quality, Build Quality, Humble Price of 15$

Cons: Cannot Really Complain at 15$

Me: I am a 21 year old student living in a small town in India. I would like to call myself a music enthusiast, rather than an audiophile. I was inspired by music since childhood, and as the time passed, the passion of music grew in me, and that subsequently led me to join Head-Fi. Eventually, I found the pleasure of listening to music mainly by the HD600 and recently, by the seductive LCD2 headphones, and realized the true components of recorded music. I usually like to listen to Indian Classical Music along with Bollywood songs. My main listening genres include classical, vocal, instrumental, jazz and sometimes pop.


Intro:  ME-Electronics is an established & popular US brand specializing in the area of Bluetooth headphones and IEM’s. They are based in Los Angeles, CA. Their products are all designed & developed in the U.S, but made in China by high standards.The HT-21 Gen.2 is on-ear Closed-back headphone offering. MEE recently updated the drivers of already excellent HT-21 model and hence the HT-21 Generation 2.

Their products are very reasonably priced, accessible for a common music enthusiast. MEE provides are a great price/performance ratio on their entire product range.


MEE’s Motto: Music Enjoyment for Everyone .


Specifications of the HT-21 Gen2:


Type: Closed back, On ear with Passive Noise Isolation


Driver: 40MM dynamic


Frequency Response: 10Hz-20 kHz


Impedance: 32 ohms


Sensitivity: 116dB (1mW@1KHZ)


Maximum power input: 50mW


Packaging and Accessories: The HT-21 Gen2 ’s arrive packed inside a strong cardboard box with a removable outer sheet, on which features and other information have been mentioned upon. Once the box is lifted open, The HT-21 Gen2 is seen resting on a plastic board. The cable is coiled off in the storage box. Which is safe yet attractive, nothing to complain about. A pouch is provided to store the HT-21’s.




Design and Build: The HT-21 Gen.2 has a very good overall build quality. Nowhere to nitpick.





The entire housing shell is made up of high quality fibre, and is painted in gloss black (fingerprint magnet). Cans are pretty small, and appear to be large in pictures. These are extremely light in weight. MEE logo is printed on the rear side of the housing shell. Left and Right markings are easy to see, and are clearly indicated. Headband & earpads cushioning are made up of soft pleather materials. The length slider is made up of polished metal, which ensures this area, which is under tension, does not break off.




The HT-21 Gen.2’s are already nimble, easy to handle, wear on and power requirement is very low. Along with all these, these are fold-able, and are easy to carry around. Cable has a very good build. It is light, flexible and does not get tangled. I could not notice the presence of any microphonics. Plug is 45 degree angled and gold plated.



Comfort:  HT-21 Gen.2’s are very comfortable to wear. and its yoke is long enough and hence comfortable for almost any-sized heads. On1 is ergonomically designed. But since the earpads are madeup of pleather, ventilation will be less, thereby causing sweating; especially in tropical climate. But it can be continuously worn over an hour without any discomfort issues.



Since HT-21 Gen.2’s are closed back headphones, these will isolate the listener from outside noise. This level of isolation is decent for a traveller. Going by weight factor, these feel extremely light and very easy on head. Clamping force is relaxed and not at all imposing and pressing against ears. Headband has a good cushioning, Also, the HT-21 Gen.2’s housings have high degree of rotation, ensuring a good comfort for any given heads and ears.



Sound: As for the most important part, the HT-21 Gen.2 has a very neutral, clear & airy sonic character. It is very transparent and detailed (given its price). We have to keep in mind that, with on-ear headphones, sonic presentation may feel different with different fit. Therefore fit/angle is the deciding factor for sound being perceived by ears.


Burn in: There is little or no sonic change with time. Let’s say a usage of 5 hours gives us softening of pleather earpads and better clamping force. Bass prior to break-in is slightly looser, and eventually it becomes more accurate, Mids will sound more open, airy and natural. Highs become slightly smoother; soundstage opens up by a margin.


Lows: have sub-woofer ‘effect’ and punchy; not very accurate.


Mids: sound very neutral, airy and clear.


Highs:  Detailed yet smooth treble.


Soundstage: Unlike majority of portable cans, the HT-21 Gen.2’s soundstage is airy natural with nearly circular soundstage. Depth is excellent. Instrument separation is very good for its price point. Instruments placement & positioning is great.  I wouldn’t call it as natural sounding, but as neutral, detailed, transparent. Low volume listening is pretty impressive. One can hear On1 in very low volumes, yet it retains all the details & elements present in a track. Comfort and fit plays a vital role in sound being perceived to our ears. Especially in case of On1 where the earpads are very compact, if they fit in a wrong way, they will leak sound leading to missing details.


Amplification: The HT-21 Gen.2’s are rated at 32 ohms, and designed to be power efficient, and hence are fairly easy to drive, and can be driven by almost any sources, smartphones and DAP’s. Although setup like an O2/ODAC does indeed increase accuracy, soundstage and dynamics, and the difference in quality is definitely audible. Power is not very important aspect here, but a transparent setup indeed does help in increasing SQ;


Conclusion:  The HT-21 Gen.2’s are really impressive set of cans, which are affordable to any music enthusiast out there. Build quality is very good, sonic presentation is very pleasing, with fairly good soundstage. I really like to listen to these cans. I have nothing but praises for these. At a humble price of 15$, these are a steal deal & no brainer! No one can really go wrong with the HT-21 Gen.2

HT-21 is meelectronics First Portable Headphone. They are already quite famous for their great price/performance ratio with their current IEM's lineup.
Meelectronics describes HT-21 as "Enjoy powerful bass along with class leading clarity and a spacious presentation, extreme comfort, and the convenience of a single cable and folding headband" 
Specifications :
Driver: 40mm dynamic transducer
Impedance: 32 ohm
Sensitivity: 114 dB
Frequency Response: 20Hz~20kHz
Cable length: 1.2m (Left sided), single-sided; 45º plug
Accessories/Packaging: The HT-21 arrives in a fairly standard cardboard box with a plastic window, allowing buyers to see the headphones. Inside, a plastic insert holds the headphones in place and and comes with a bundled drawstring bag, although made from crummy textured plastic it’s a cheap addition that shouldn't figure in your buying decision.
Build Quality : The HT-21 is a closed-back supraaural headphone which can be folded flat and collapsed to save space during transport. The overall feel of the headphone is quite light, which is aided by the plastic material used for the majority of the construction. The ear cups are padded with leather like material. The headbands are flexible for height and the ear cups are also foldable which can be folded flat and could be carried easily in the carry bag included
Cable: The cable is thick and flexible and is well relieved with a hockey stick shaped L-plug
Comfort: These IEMs are very comfortable to wear,being an oval shaped insertion design that allows these to pretty much disappear in ones ears. Deep insertion levels as well as wearing them over the ear are not possible due to the oval shape.
Isolation:  Noise isolation is nearly nonexistent despite their closed-backed design
Sound Quality: 
Burn-in: Its been burned to 100+ hours before the evaluation.
Amped / unamped: Not much of a difference, these are drived easily by even low power sources
Lows: The bass is a bit punchy but it’s not very deep, they do sound tight and well controlled
Mids: There is an overall smooth presentation of the mids and clarity is an obvious strong point that stands out with these headphones.It is crisp, clear and blend well with the highs and tend to lean very slightly towards the cool side of the spectrum on the whole
Highs: They perform the same way as the mids- crisp, clear with decent extension. Though a bit of sibilance can be observed with bad recordings more at high volumes
Soundstage: Sound stage is airy and good for a closed set, definitely ones of its pros, the 3D layering and differentiating is quite good particularly in clarity and control
Final Conclusion : The HT-21s are a great choice for anyone looking for a comfortable and portable set of headphones that won’t break the bank. While not overly proficient in any one aspect, they are certainly competent in all areas. Sound quality is highlighted by excellent clarity with no glaring weaknesses, and the comfort and portability factors round out a nice package


Pros: Portable, Lightweight, Powerful Mids, Crisp Bass

Cons: Ear Pressure, Painful Highs, Plasticky

I bought these on Cyber Monday for $15.  I read a lot of reviews and thought they might be a good inexpensive portable pair.


My problem, is I think I expected too much from the HT-21.


The best way to describe the sound is "Echoey/Clear".  The sound is slightly recessed, but at the same time, there are some sounds that come through powerful and clear.  It is the strangest thing.


The Highs are HIGH.  Painfully so.  An EQ is needed on any device you plan on playing these through, to subdue these tones.


The Mids are Powerful.  You can hear vocals come through in songs very well.  And in this respect, I actually enjoy using the HT-21 when I am watching a TV Show / Movie.  Dialog comes through perfectly clear.


The Bass is light, but very accurate.  And in this, the best part of the HT-21 is the light bass.


These are the least comfortable headphones I have ever worn.  The weird size of the pads places a lot of pressure on my ears.  I think this could be fixed slightly by stretching out the headband, but not by much.


I don't want to give up on the HT-21.  My less than par review is not going to stop me from listening to them.  I keep wanting to give these little cans "one more chance".
