Meelectronics R1 is a perfect IEM for Bass Lovers, With the recent price drop, this is a steal for bass heads. R1 has been redesgined and updated from the initial version and is very much improved a lot in terms of SQ.

A complete review on R1 :

Accessories : My purchase had a pretty good set of accessorries though the official website doesnt show some of them, My R1 package came with:
1) 1 Shirt clip (Attached with the IEM itself)
2) 4 pairs of Clear silicon ear tips (3 sizes Single Flanges, 1 Double Flange )-
3) Hard clamshell carrying case- Pretty hard case on the outside with good soft material on inside making earphones secure to carry on the go
4) Cable Winder - Made of rubber, makes portability better
5) Airplane Adapter

Build Quality : Housing is made up of coated bright colored wood. Cable has a L-Plug, similar to the meelec M6,M9 cables but more durable and is a bit microphonic.

Isolation : Average when compared to other Meelec IEMs, But isolates a lot whenused with Small single flange tips as the houses just blocks out the noise.
 
Comfort: Most might find that Small sized tips much comfortable. Other sized tips might not be comfortable, since the bulge of the housing makes it uncomfortable, using comply tips might just solve it

Sound Quality:

Signature: Bass oriented Signature, mostly warm type

Lows: Very deep, smooth and warmness gives a good punch to it
     
Mids: Not much clear or detailed, slightly recessed, thin sounding than Meelec M6/9, mids might not be much prominent as it is warm. Though, lower mids are smooth, full and balanced, Upper mid range frequencies are harsh

Highs: Not much of treble, enough of it though. Its warm, smoothed down on the treble mostly. Higher trebler frequencies are little recessed, overall a good performer on the highs

Bass: Bass is pretty much full in depth and strength too. Even though its in quantity, its softer and pleasant on the whole making a strong point for the bassheads

SoundStage: Instrument seperation isnt good. Soundstage is below average due to the excess warmness

Final Verdict : Might suit as the cheap and perfect choice for bassheads, built well, can be durable, If you want balanced , neutrality, clarity and detailing, better stay from it.

My first purchase from Meelectronics was M6P, I can simply say, Im just amazed by the quality of this product. I had many IEMs before in 30-60$ price range, but this truly indeed is my pick of them.

Heres a detailed review on M6P :

Accessories : Well, Meelectronics really cant go wrong in this part, they provide a solid package of Accessories for all of their products. M6P comes with
1) 1 Shirt clip
2) 6 pairs of silicon ear tips (3 sizes Single Flanges, 1 Double Flange and 2 sizes of Triple Flanges)- Tips are pretty much the best silicon tips Ive used with, they are reasonably durable with good comfort..
3) Hard clamshell carrying case- Pretty hard case on the outside with good soft material on inside making earphones secure to carry on the go

Build Quality : Cable is pretty solid and has low-profile L-plug, Housings are made of plastic. The over-ear cables has a 2 inches of memory wire. Cable is reasonably durable, microphonics is very less and can be avoided by using the clip provided.

Isolation : This suprisingly isolates a lot, particularly with Triple Flanges,Double Flanges. Might work well for gym and running.

Comfort: This is where this IEM lags a bit, since its over-ear, the memory wire can cause fit issues for some. Experiment with different sized tips might solve it. With a little knife work, memory wire can be removed making it wearing straight down which might solve it for some, Comply T400 is another alternative which isolates well with good comfort

Sound Quality:

Signature: V-Type Signature
Mids: Mid is slightly recessed but has good clarity, range, extension
Highs: It has good crystal-clear detailing at top of the range, it is little bit bright and is relatively smoother
Bass: This is where M6 Shines, Bass Control is good for the price, mid-bass hump gives a good overall balance, has good impact and body
SoundStage: Pretty good with decent airiness

Final Verdict : Taken as an entire package, M6 is just a bang-for-buck at its price. It is a very good allrounder with perfect steal for trance and electronica listeners though it serves all genres well. Add the amazing Meelectronics Customer Support, you should not worry for techinal/breaking issues. They just have the best technical support to assist you with any problem and might just give the edge over the other IEMs at its price..

S6 was my second Meelec IEM after M6, which I was thoroughly impressed with, though it shares the same sound with m6(same signature), its a bit more less mid-recessed than m6 in terms of SQ comparision. Cable is a LOT durable, stylish and sleeky than m6s. More accessories included.
 
I had monster isport before, I must say this is far better in terms of everything,they literally broke after a few months of usage, isolation wasnt that great, SQ isnt the best too. This IEM might just serve as a good cheap alternative for sporting activities like gym,running etc.

Heres a detailed review on S6 :

Accessories : Well, Meelectronics really cant go wrong in this part, they provide a solid package of Accessories for all of their products. S6 comes with
1) 2 Shirt clip(attached to IEM)
2) 6 pairs of silicon ear tips (3 sizes Single Flanges, 1 Double Flange and 2 sizes of Triple Flanges)- Tips are pretty much the best silicon tips Ive used with, they are reasonably durable with good comfort
3) Hard clamshell carrying case- Pretty hard case on the outside with good soft material on inside making earphones secure to carry on the go
4) Extension cable
5) Neoprene Arm Band - Looks fancy and is made of good quality indeed.

Build Quality : Cable is pretty solid and has low-profile L-plug, Housings are made of plastic. The over-ear cables has a 2 inches of memory wire. Cable is a lot more durable than of m6, but is small(18inches approx), an extension cable is provided though. Microphonics are pretty much non existent.
Isolation : This suprisingly isolates a lot, particularly with Triple Flanges,Double Flanges.
Comfort: This is where this IEM lags a bit, since its over-ear, the memory wire can cause fit issues for some. Experiment with different sized tips might solve it.With a little knife work, memory wire can be removed making it wearing straight down which might solve it for some(with the expense of bit isolation), Comply T400 is another alternative which isolates well with good comfort (comfort is on par with m6)

Sound Quality:

Signature: V-Type Signature
Mids: Mids are better than m6 has good clarity, range, extension, but still somewhat recessed
Highs: It has good crystal-clear detailing at top of the range, it is little bit bright and is relatively smoother
Bass: This is where S6 Shines, Bass Control is good for the price, mid-bass hump gives a good overall balance, has good impact and body
SoundStage: Pretty good with decent airiness

Final Verdict : S6 might be the best budget IEM for sport in 30-70$ range, they just sum up good as a package. Add the amazing Meelectronics Customer Support, you should not worry for techinal/breaking issues. They just have the best  technical support to assist you with any problem and might just give the edge over the other IEMs at its price range!
