Hi all!
 

I was going to post this review last week, but I wanted to test these phones with some foam tips, so I spent an additional week or so doing it. Moreover, this is going to be my last review for a while, because I'm a bit tired of listening to music for testing phones, I want to just enjoy music without worrying about taking notes or evaluating the sound, at least for some time.
 

We are dealing here with the A151, the first balanced armature phones from Meelec, and in many ways a big change from Meelec usual lineup: housings made of plastic, twisted cable, balanced armature drivers, etc.
 
These are the phones:
http://www.meelec.com/MEElectronics_A151_Balanced_Armature_In_Ear_Headph_p/ep-a151-bk-mee.htm
 

They retail for about 80USD, and probably the first thing will catch your eyes is the cable, very different to the metal-braided, silicone-coated characteristic Meelec cable. No "P" (with microphone) version is offered yet.
 
But let's go to the matter!
 
 
 

Building quality, appearance. The A151 are only offered in black, which in my humble opinion fits quite well. I must confess that I love black phones, so maybe I'm biased here!. The housings are reasonably small, but in my opinion they should be smaller, the balanced armature drivers allow for it. Still, once inserted, they have a smaller profile than many other phones I've tried, so size is not really a problem. Although the housings are made of plastic, thus departing a bit of Meelec typical metal housings, the building quality is astounding.
 

I have to insist on this point. These phones are not as cheap as the old M9, which I've always considered Meelec flagship, and the M9 were made of metal, so some people may think that plastic housings could mean less building quality, but that's not true. The plastic is sturdy and very well made (no molding lines, superb finish, etc.), so you won't miss the metal, that's for sure.
 
Here you can see a photo of the housings with my blotched homemade foamies:
 

 
 

Yes, the foamies are a bit short, I'm working on it 

 And they're a bit dirty. I'm not working on that, yet. In the photo you can see, too, the piece of rubber that keeps the two cables together when you have to put the phones in the carrying case. It's a bit unusual for me, but I don't have much experience with that kind of cable!
 

The cable is astounding, too. I haven't used phones with twisted cables, only tried them once or twice, and I was never a fan of this kind of cables. To me, they looked weak, so first time I tried the A151 I must confess I had a bit of prejudice about the cable. Now, I've changed my mind. I don't know if this is the rule about twisted cables, but this one is fantastic. Very flexible, not tangle prone at all, very comfortable and with no microphonics at all. I love it, and I would love to see it in other Meelec models in the future.
 
Here you can see a photo of the cable, featuring the Y-split and the plug:
 

 

The plug is the usual 3.5 TSR jack, straight. I prefer L-shaped or the 45-degrees you can find on some Meelec models, but that's a matter of taste. The jack has a quite low profile for being straight, so I can live with it. Looks sturdy and fits quite good on my Clip+:
 

 
 

 
 

Together with the phones you receive the typical Meelec clamshell carrying case (photo below) and five sets of silicone tips, small, medium and large single flange, a pair of biflanges and a pair of large triflanges.
 

 

 
 
The bi-flange tips are a bit big for me, so I haven’t tested them extensively. I couldn’t get a proper seal with them.
 

The tri-flange tips weren't very comfortable and I lost the seal with them, don't ask me why because they're by no means small, and I could insert them quite deepely. I didn’t test them much, either, because of that. They're the same as the ones provided with the M6, and in fact they work very good for me with the M6.

 

The big single-flanges got me the best seal and isolation, but weren’t very comfortable after some time, because the phones slided out of my ear.

 

The "fake Sony hybrids" (not shown in photo) worked much better for me, but not as good as I expected. They work much better with the M6, for example, and I don't know why.

 

I also tried the black foamies included with the SoundMAGIC PL50. They fit perfectly, are fully comfortable and doesn’t make the sound “darker”. They worked like a charm, but had a big problem for me: they become VERY soft when warm, so after an hour of use or so, the seal is not as good as when firstly inserted.

 

Finally, I tried homemade foamies, which worked perfectly. I'm using them right now and I'm happy with them.

 

Clearly, these phones are calling for some foam tips and better silicone tips. The included are not bad but they are a bit far from the “fake hybrids”, for example, and my homemade foamies worked much much much better.

 

 

 

Comfort, wearing. If you want to make it short: they're VERY comfortable. They take some time to get used to inserting them properly, but not much, and once inserted they keep there (when using the appropriate tips) and you barely notice you're wearing them. They're very light, the cable is so soft that adapts perfectly to the shape of my ears, and the housings fit quite good in my outer ear.
 
They're designed to be worn with the cable over-the-ear. This way of wearing phones has a very clear advantage: almost removes microphonics. But it has a clear disadvantage in my case: cable insists on jumping over my ear as soon as I move my head left or right. With the A151 this problem disappears because the cable is very soft and adapts perfectly, so no cable jumping 

 
I've tried to wear them cable-down and although I could, I didn't like it much because the phones tended to slide out of my ears that way, if I used silicone tips.
 
I've already talked about the tips. In the end, only my homemade foamies did the trick in terms of comfort and isolation. I don't have Comply tips compatible with this model, and it's a pity because I think they will be perfect. Meanwhile, I have other foamies I can use.
 
I'm very sorry for not being able to use the provided silicone tips. Foamies are a pain in the arse when inserting the phones, but silicones didn't offer comfort and good seal to me. Maybe it's the design, who knows, or maybe it's a problem with my ears, but phones usually tend to slide out of my ears, specially from the right ear. With most phones is just a matter of finding the silicone tip that does the trick (fake Sony hybrids usually work great), but with the A151 I didn't have any success. For me and the A151, foamies are the way to go for now.
 
The housings are a bit on the big side, but nonetheless the phones can be inserted deep without problems. At least I didn't have problems, and my ear canals are weirdly shaped. They allow for a bit of rotation once inserted, so you can move them a bit in the ear to gain additional comfort.
 
I've used them for 10 hours in a row or so without any problem, in fact I almost forgot I was wearing them! My contact lenses are much less comfortable after only 6 hours 

 
 
Noise isolation, sound. To be sincere, the sound signature of the A151 is not my favourite (I'm a lover of the CC51 sound signature), but they have surprised me. I thought that I could only use them when I do critical listening, where picking the details is important but you won't enjoy the music much. I was wrong, I can do critical listening with them while at the same time enjoying the music, because the sound signature is not cold or harsh, no matter the amount of detail and accuracy you get. I really like this, because I thought that I would never find a balanced armature that I really enjoy.
 
First thing I noticed is that even at low volume there’s a lot of clarity, detail and accuracy, which is the same I thought when I first used the SoundMAGIC PL50. At normal listening levels, the degree of detail and accuracy is just incredible. I've discovered new details in my music that even the PL50 missed. Problem with this is that the A151 are very revealing about source limitations. If you listen to poorly encoded music or your source just stinks, the A151 will throw that in your face.
 
Second thing I noticed: no need to amp them at all. My Clip+ didn't had any problem moving them, and adding the FiiO E5 to the equation didn't improve things much (well, basses improved a bit).
 
Third thing: the basses doesn't suck. I haven't tried the Westone 1, but the SoundMAGIC PL50 had very weak basses in my opinion. In fact, that's the reason I don't use mine (my wife likes them, though, so she's using them happily), I feel like music lacks presence, and from what I've read, that's a common problem of single balanced armature entry models. Not with the A151.
 
I have to make things clear here: you won't get the basses of the M11+ or the CC51, even the CX21 has more basses than the A151, but compared with the PL50, the A151 kicks a**. The basses are clearly there, they have impact and they're very well controlled if you ask me. They lack in depth, that's the price you pay for balanced armature drivers, and the sub-bass response is... well, armature like (almost missing).
 
The mids are probably the part of the A151 sound that I like the most. Balanced armature drivers are very detailed in the mids, usually, but at times they sound cold, analytical, and that ruins the overall effect. The A151 add a bit of warmness to the mids (well, to be sincere, to the entire spectrum, is a characteristic of its sound signature), so you can listen to Sade, for example, with great pleasure. Female voices benefit from this added warmness and thickness, no doubt, and that's why this is the point I like the most about the A151.
 
The highs are very detailed, but not harsh. I haven't noticed any sibilance, which is good, but I miss a bit of sparkling. And not that I think the highs are laid back, but I wouldn't mind them being a bit more forward. No complains, though, because in my limited experience, when highs tend to go a bit forward, harshness and thrilling sound are waiting for you...
 
At times, they’ve sounded congested, or for a lack of a better word, crowded. Not exactly the phones fault, as the same music also sounded congested with other phones, but the A151 showed this problem more. This may be caused, probably, because the revealing nature of the phones. Well recorded music sounds great, but poorly recorded music sounds even poorer than with more fail-tolerant phones.
 
Soundstage is only average to my ears. The CC51 were better here, in my humble opinion, and they haven't a very wide soundstage either. It is more than decent, though. Instrument separation and placement is superb, as it should with the level of detail the A151 gives.
 
Noise isolation is slightly above average. I would have expected a bit more of isolation from a balanced armature, but well, when music is sounding the isolation is quite good. Probably if I could find some silicone tips that work for me, isolation would be better. With homemade foamies you can have isolation problems if the foam is soft, for example, so I don't want to judge A151 isolation from my experience, as I know other forum members consider it above average in these phones.
 
 
Summing up: For a slightly warm sound signature, together with the accuracy, clarity, detail and speed of a balanced armature, this phone is perfect for the price. Being a bit more expensive than the SoundMAGIC PL50, it offers better bass response, better ergonomy and better building quality, so the price difference is justified.
 
For the same price and an alternate sound signature (colder, more balanced except for having more and better basses), you can buy the Meelec CC51. For the same price and sound signature... you will have a hard time finding something 

 
I don't know if Meelec has plans about releasing a dual armature or something like that, but given the quality the A151 gives for the price, anything above it would be just marvellous. I would love to see housings on the line of the Ety ER4, because they would be perfect for my ears and would give the noise isolation I desperately search in IEMs!
 
A great phone at a great price, but with a balanced-armature sound signature, so caveat emptor.
 
Comments and questions welcome, as always! Hope you enjoyed the review.

Thank you! I was about to create a thread of A151 vs CC51. I guess I will go with the A151 because the braided cable seems to be more durable and the A151 has a better built overall (correct me if I'm wrong.)

The A151 has not a better building quality than the CC51, in my opinion. The only real difference is sound signature.
 
If you want to do some critical listening and won't miss basses, go with the A151, because IMHO the cable is better. In fact it is marvellous.
 
If you want an all-terrain phone, high sound quality, incredible looks, go with the CC51. The cable is not bad, it's just that I like the A151 cable much better. And yes, in my humble opinion the CC51 could use a better cable and the shirt clip should be easier to remove, but anyway you will be getting a superb phone.
 
Tell me your music likings and maybe I can recommend one of them. Myself, I can't decide. I suppose that if I only could keep one, I would choose the CC51, I'm in love with its sound signature. But I'm happy I don't have to decide, because I have some uses for both.

Thank you. It's so hard to decide because they are in the same range price and I haven't had a chance to listen to any of them. However I really want to have a budget friendly IEM that has a strong & durable cable because I've had some bad experiences with flimsy cables before.  
 
I usually listen to pop/funk/soul songs with a bit of disco elements: http://youtu.be/pz4uSYaGfi0
(Sorry I know the YouTube quality ain't great.)
I also love RnB female vocals so I guess I like it a bit warm & detailed like this one: http://youtu.be/bC7V9dn1rC8

thanks a lot for that! nice review! great format!

 

[50an6xy06r6n]

Great review! I'm just wondering though, how does it compare to the CC51? I have the A151's, so I'm wondering what the differences really are. Also, I too had issues with the triple-flange tips, and I think it's because they're long, but not wide enough to really fill my ear canals. But overall, great review.

 

[DervishD]

@bigbeast: if you want detail and warmth, and are a bit worried about the cable, go for the A151. I would keep an eye on the CC51, though, if I were you. I think it's great to have both, to be sincere, as they complement each other quite well.
 
@Portable Mink: thanks a lot, really
 
@50an6xy06r6n: The CC51 is less detailed but the basses are better. Moreover, the sound signature is more "all-terrain" than the A151. I like them better. The real advantage of the A151 are the detail and accuracy, as they're balanced armature. For other characteristics, I would go with the CC51.

Thank you again! Your review is very helpful. I look forward to reading your reviews in the future.
 
I will definitely keep an eye on the CC51. They are both great deals for the their price.

Awsome review! especially the comparisson with the pl50
my ordered pl50 are on their way, and i was considering of getting (maybe also) these a151 (although the shipping cost is $20)
im still not sure whether i should get the a151 or something else from meelec or other brand, but maybe i ll give the pl 50 some use before getting something else

That's probably the best idea. You first want to determine if you even like the sound that balanced armatures give you, or if you'd prefer something with a little more bass, a la dynamic driver IEMs. So spend some time with your pl50 before making a decision about your next purchase. Plus, selling them if they're not to your liking will allow you to recoup some of their cost.

 

[seanmo]

I recently got the a151 on the one day buy.com $50 deal and got the pl50 around the same time.  I returned the a151 nad kept the pl50's.  Loved the build quality of the a151 and the cord is insanely good for the price, but the sound didn't do it for me, felt to warm and colored in the mids for me...hard to describe but the sound was a little 'gritty' for me.  PL50's to me had a more pleasing sound and were more comfortable.  Just my opinion as a lot of people seem to really like the a151.

^I think joker stated that the two use the same driver, so objective sound quality should be more or less the same. They are simply tuned differently. And to each his own preference, obviously.

Impedance is different between the two, so it is not the same driver, just the same kind of driver - Knowles Siren I presume. Though they both share the same kind of warmish sound inherit across the Siren line of transducer,  they don't actually sound very alike. A151 has a more revealing sound but at the same time is quite intimate. Compare to PL50, it might lack a sense of relaxation and openness.for some.
 

 

[goodvibes]

ClieOs, I was looking for another siren type with those specs and couldn't find it. Any Idea where they get it? Listening to the Sherwood and PL50 will show how different even the same driver can sound. There are similarities but I doubt anyone would guess those 2 use the same unit. By the way, thanks for shedding light on the SE-777. I picked up a barely used pair based on your and I think, shigzeo's review and changed the front filter with something less restrictive. They were a bit dark as stock. They're a lot better than what I could ever get from the pl-50 and the construction is amazing. Driver is shock mounted with an interior rubber case under the metal one. pretty good isolation too. Using M1 tips. Looks like they're gone now. By the way, if you look at the Knowles siren spec sheet, the driver is phase inverted as marked.

 

[ClieOS]

Yeah, Knowles doesn't list most of their Siren drivers spec on their own website anymore. Anyway, if you have the SE-777, then there is no need to get the A151. The two share a very similar sound.
