How is Monster iSport?

I just got a pair of these to use in the gym.

It's hard to comment on them for anything other than gym use though.  Compared to my everyday headphones (SM3 and SE535) they aren't in the same league, and I'm not in a position to recommend them for everyday phones (I've only listened to them in the gym).

I bought them as I needed something that can deal with water in the gym (I'm horribly sweaty in there) as every other 'sport headphone I've used has randomly cut out on me and doesn't stay in my ear.

So I got a pair of the iSport last week and they are perfect for what I wanted them for.  Lightweight but not flimsy.  Decent bass without being overpowering.  Plenty of tips (non foam which is much better for the gym), and they stay in place well due to the plastic in ear clip things.  No idea how they sound for most types of music, but for what I listen to in the gym (usually some type of dance or hip-hop with decent bass throughout) they do a job very well.  I'd recommend them.

But are they comfortable enough? I have a pair of miles davis tributes and the only earbud that fits me is the smallest regular single flange. I just ordered a pair of monster sports on amazon and am really worried about the fit. I've read all the reviews and fit really depends on the person and it's a good 50/50 split at best with some proclaiming it as the best they've ever tried on and the rest complaining that it's unusable. I just need these things for running and going to the gym and could not find anything else as convincing to buy. 

i have tried once, no deep impression~ 

I bought a pair of Monster iSport last week.

This is not my first IEM. I already had Etymotic ER-6 (hate them !, They were too big for my ears. They never fitted, and they stopped working completely for no reason !), and JVC HA-FXC50 (love them).

Unfortunately my FXC50 got quite used, I have them for three years and they don't sound good any more. I love the wing which fit the device in the ear very nicely. They were very confortable, and I can put them in my ear in one second. They also provide rather good isolation.

The iSport has another shape. They are not as easy to put on (it takes me 10 seconds to wear them).

They don't provide as much isolation. (slightly less)

ljokerl rated the HA-FXC50 in http://www.head-fi.org/t/478568/multi-iem-review-238-iems-compared-astrotec-am-90-added-05-21-12

as Confort: 3 / 5 and Isolation: 3.5 / 5 (it seems I would have rated them Confort: 4.5 / 5, but I'll stick to ljokerl rating for comparaison)

Using the same scale I would rate the iSport as Confort: 2 / 5 and Isolation 3 / 5.

They came with 5 ear clips and 5 ear tips (XS, S, N, L, XL). I choose the S ear tips and the N ear tips. They fit pretty well, but my left ear hurts after 1 hour. Maybe I will get used to it. My right ear doesn't have any problem (rate confort: 2.5)

Now for the sound. I cannot compare to my JVC FXC50, because they no longer sound good, but I am very, VERY, satisfied with the sound of the iSport. See the attached screenshot of Foobar equalizer. The correction is so light that I am very pleased to the sound without correction (in my mp3 player, while running, or working).

The frequency response is pretty flat, including the low end. They also go lower (20 Hz). The bass are really awesome, medium is good also, and the treble are pleasantly clear without being harsh.

So I am very pleased by my purchase. I will also receive a pair of JVC HA-FXC80 in one week. I will update my post some time after.

how's the fitting? i heard it's pretty bad to fit nicely inside your ear, considering to get one mainly for gym and outdoor purpose

Once you find the right size, the fitting is easy, but it requires some moves to get a perfect fit. It takes me about 10 seconds by ear.

It is secure, pulling (gently) the cable won't make the ear plug to pop out of the seal. But again, you'll have to get used to put it correctly. (relax your jaw by opening your mouth, then slide your ear to insert the IEM).

My previous HA-FXC50 were a lot more easier to fit, but they were also slight less secure. Anyway, with the iSport, you won't be able to wear them/remove them everytime someone talk to you. Fortunately, at the office, it is possible to not attach the ear tips, so the fitting is faster (but the fitting is not secure at all, of course).
