Pros No kidding, this relatively low price headset is high on quality. I tested MM50iP with Shure headset and actually find the MM50iP offering equal or better sound quality. It picks up alot of notes on a track and its bass is very good for the price.
Cons No casing to store the headset and a little wind pick up but bearable as most in-ear headset does pick up wind.
Summary You will discover a full range of sound and notes as this headset is capable of picking up the details of any quality track. I like bass and this headset does magic with bass. The mic works well with my Iphone with no complains from callers or myself in any phone calls. At a price this good, I can't find any rival headsets that come close to a MM50iP.
Pros Small form-factor - comfortable and light.
Good bass response and good sound detail across the range.
Long narrow plug good for phones with protective cases
Cons Treble is loud and 'hissy' at higher volumes
Straight jack connector feels like it could lose connection with normal use - angled connector would be preferred
No volume controls
Microphone is only average quality - does not cut out ambient noise
Summary Surprisingly good sound quality for the small form factor, once you get a good comfortable seal in the ear canal (which isn't hard compared to some others I've tried.) Bass is good and sound detail is great across the range, although the top end is 'hissy' and uncomfortable at higher volumes. This can be rectified by using iPhone's equalizer (I found Bass-Boost or treble reducer the most effective, but amazingly these small phones don't really need a bass boost!)
The microphone is only average, picking up surrounding noise quite clearly for the person on the other end of the line, to the point of distraction. The push to talk button is small and hard to find. On a pair of headphones specifically designed and marketed for iPhone, it's underselling the customer to not also include volume controls.
Apart from sound quality which is well above average, everything else seems average. The rubbery cord is prone to tangling and the plug is straight and feels like it could break easily with wear and tear. The same goes for the thin wires that connect to the actual buds.
There are products with better all round design out there. At MSRP they're a little pricey for considering the lack of design consideration. But if you're looking for good quality sound reproduction in a small package, and only take calls on your phones occasionally, these are good product, especially if you can get them on sale.
Pros Music quality is very good.
Cons The minute you start walking, there is a VERY distinct and annoying thumping sound every time the cords rubs against your clothing in the chest area - every step you take. You have to stand still in order to listen to the music!
Summary Thumping sound is too obvious and renders the headset useless.
Pros Excellent Sound quality including bass. Also on a 5k run they disslodge out of my ear normally only twice. Like the shorter cable with mic on one side. Puts cable to the side of body not down the center.
Cons Rubber cables taggle too easily requires cord managagement when finished using.
Summary I mainly listen to my music during excerise or using mass transit. It has been hard to find a set of buds that stay in the ear once you start sweating. Thou not perfect they eventually shake loose but only once and awhile, which I can deal with. And during these activities I place the cord under garments so having the shorter earbud and mic on one side naturally make the wire hang to the side of the body where I attached/put my iphone. Great sound quality and one will argue there are better sounding earbuds but for the price and if you shop around you will not be dissaponinted.
