Reviews for RHA MA450i Noise Isolating In-ear Headphones with Mic

These are the best earbuds I have ever purchased. The sound is really good, the buttons on the mic are sufficiently differentiated (I hate to try to push "play" and hit "volume" because all the buttons feel totally the same) and best of all, they are actually comfortable!!! I have very small ear canals and the headphones come with numerous silicone buds that make these a great fit for most any size. Only complaint (and it is minor) is that the cord is much longer than normal (from tip to tip, almost 5 feet long) so it's more likely to get tangled.

sounded really good out of the box. they seem to pick up and transfer to the ear a lot of noise (when the cable rubs agains your clothing for example). probably due to the fabric wrap on the cable. that makes these annoying unless sitting still. the fabric wore out at the base of the jack about a month after purchase. the left headphone failed after 2 months. for 50$ i expect to get more then 2 months of use.

Earbuds hang in your ears and let you stay connected to the outside world. These in-ear headphones shut you right out. Which can be a good thing.

The headphones come with extra rubber covers, and the size makes all the difference. Too small and the earphones were really uncomfortable -- like someone was stabbing my eardrum. Too big and they wouldn't sit right and sounded weird. I liked the middle ones. Also, when they fit the scratching noise from the cord is less an issue. Sound is definitely better than the ipod buds, but they're a different animal.

The mic for the phone works pretty good too.

I bought these headphones for a month now and have not had any issues with them yet. The sound is very clean. Some headphones sound muffled or too bassy or too something, but in my opinion, i think these sound balanced. The bass isn't overly powerful, the mid and tweets i think are pretty clear. Like some other reviews have said, the tweets/highs are more distinct. I think thats great because some headphones lack tweets but give too much mid or bass. I'm a mechanic at an auto shop and when i put these in, i can still hear the things around me but they do quiet down a bit. I only need to use the volume on my iphone at 1/4 of the way and i will get a nice comfortable listening feel. I can hear the music, but at the same time, im not deaf to whats happening around me either. If i put the volume to 1/2, i cant hear anything around me anymore and the music becomes alive in my ears. Haven't listened to them at 3/4 but im sure it'll sound good. I listened to it with all sorts of genre, and in my opinion, it is great. One thing that can be worked on is the noise the line makes when rubbing against anything. If yo have the volume on low, the rubbing noise is super intense and loud in your ear, but if you go past the 1/4 volume on the iphone, the rubbing noise does go away. I use the 2nd biggest earpiece and it fits perfectly. I like the play/pause button, it works like magic. I say that because i use it to use Siri. I can just press and hold the play/pause button to ask Siri to read and send messges without even takeing out my phone, which is great because my hands are usually messy. I use it to listen to music when i sleep too and they do not hurt my ears at all when im laying on my side. Overall, great sound, great feel, very light weight and comfortable. Besides the noise issue if in low volumes, anyone who picks this up i believe will enjoy them for the price you pay. Dont forget the 3 year manufacture warranty that comes with it, tell me that isn't the darnest deal ever. That was the selling point for me because i use them a lot, not abuse, but use.

They are as good as advertised. Actually better. I now have no problems as I did with Apple's earphones of them falling out every other second. They are definitely noise canceling which is nice when little children are in the area.

These might be the best sounding earphones I've used with my iPhone 4, very clean, detailed sound. However, they don't work well at all with my Macbook Pro, there's a lot of hissing and static noise and they're too loud.

I did some Googling and found that these are low-impedance headphones, which means that they don't need a lot of power to sound good which is why they work so great with my iPhone, but Macbook Pros need a higher-impedance headphone for good sound.

I have a pair of over-ear Bose headphones that work great with the Macbook, I was hoping to have smaller ones for traveling but I guess I'll stick to using these with my iPhones and the larger ones with my Macbook.

The sound is among poorest of any head phones I've ever had. I run and I'm a huge consumer of the disposable one dollar amazon knock-offs. Most of those sound bad, but these RHAs are by far the worst.

They have to be IN your ear. Not in your ear like normal ear buds are in your ear. They actually have to be inside your ear. It's uncomfortable. But the good news is that they won't stay there very long. They fell out very frequently. Even pivoting my head between two monitors at work caused them to fall out at a rate of about once a minute. They come with an assortment of tips that increase in diameter. I wasn't able to find one that fit. I couldn't try them all because it is very difficult to change. When they are in your ear properly, it sounds like you are wearing ear plugs or you are under water. Hold your hands tightly over your ears and turn up your stereo uncomfortably loud...That's what these sound like. As others have mentioned, any movement of the cord caused a noisy disturbance.

Looking at the reviews most people love them. I don't get it. I guess me and my apparently misshapen ear holes will be returning these and purchasing something else.

Surprisingly good sound for a lower priced in-ear set. After breaking it in for about 2-3 days the bass is nice and pretty strong, clear and doesn't muddy up the rest of the spectrum. The trebles take some time to settle down but can still be a bit harsh at times but I've found out that the Comply Foam take care of this for the most part. The build quality of the housing, mic and cable are very good and have a premium feel to them. Despite being a braided cable there is no sign of kinking up or cracking but they can get tangled and the straight plug isn't really ideal.

Very good quality headphones for a great price, nice bass, and rich audio.
