Pros: Pros: Build Quality, Bass, Warranty, Cable, appearance
Cons: Mids are slightly recessed, don't stay in your ear too well, cable noise
First off, I would like to thank RHA for sending me the MA350's for a review!
I am going to get right into the review now.
Driver size: 10mm Mylar
Frequency range: 16-22,000Hz
Rated/max power: 3/10mW
When I first received the MA350's and opened them, the packaging was good. A rectangle cardboard box with a plastic cover in the front, displaying the headphones. On the back you can see the specs of the MA350's, and a paragraph on why they were designed. The packaging is great for a $40 earphone. When I opened the box, inside I found a users guide, small and large tips, (The medium size tips are already on the MA350's) and a carrying case. It doesn't come with lots of accessories, but that isn't really an issue.
Accessories: The MA350's come with 3 sizes of tips. Small, Medium, and Large. They also have a nice, velour type carrying case. The carrying case is black. It is plenty big for the earphones. You couldn't fit an iPod in the case, but if you need to, possibly an extra earphone or two. The case has a drawstring on it, so you can tighten and loosen the case if needed. One thing about the case though, is how it attracts dust and pet hair. I dropped the case on the floor just to test it out, and a lot of dust/ pet hair got on it. The pet hair was easy to get off, but the dust was nearly impossible to get off. Unless you plan to show off the case, it shouldn't really be a problem.
Build: The build quality on the MA350's is very nice. Every time I hold them in my hand, I can't help feeling how smooth they are. The MA350's are made out of Machined aluminum. It is very solid. I have not found any faults in them at all, and they seem like they will last a very long time. The earphones come with a 3-year warranty. Unless put under a lot of stress, the MA350s shouldn't break under normal use. The cable is a well built, braided cable. It seems nice and strong, and I don't think it will break anytime soon. But having the braided cable, the cables rubbing is pretty annoying. The tips are kind of difficult to get off, so when taking them out of your ears, a tip shouldn't fall off. The warranty includes complete coverage for 3 years from the date of purchase, so if you manage to break them, RHA has you covered.
Appearance: The MA350's from the back are all black, with the RHA letters on them, in a nice white color. From the front, they are a nice silver aluminum color. The two colors go together very nicely. When worn out in public, I didn't get many looks or stares. But when paired with a bright outfit, the earphones compliment the outfit very nicely. One thing I thought could be different color was the Right and Left markers. The "L" and "R" markers are black, on top of the same color black, which in dim light, made it very hard to see which is which. The ear tips are black. The overall appearance, is simple, yet stylish.
Comfort: As with most earphones, comfort is subjective. I found the MA350's to be comfortable for around an hour, until my ears started to become a little sore. The MA350's really didn't stay into my ear too well, falling out a little too frequently, causing me to not get a good seal. When I could get a good seal, the isolation was average for an IEM. The comfort/ isolation may be better with different tips. Overall, the comfort / seal wasn't up to par.
Sound: The sound on the MA350's is pretty good. I wouldn't say the best bang for your buck at $40, but definitely worth the full retail price.
Bass: The bass is very good. There is a decent amount of Sub-bass and a nice amount of Mid-bass. You will get the nice rumbling lows, and plenty of punchy-ness when you need it. You won't find any muddiness or bloated bass here. The bass play's in nice with the other frequencies, by not overpowering the mids or treble. But, there isn't a large enough quantity of bass for these earphones to be deemed a bass-head headphone. So bass-heads should look elsewhere.
Mids: The mids are slightly recessed. Just slightly. Not really enough to called be a v-shaped earphone, but the mids are slightly recessed.
Treble: The Treble is pretty nice. It is bright and sparkly. The is a little bit of sibilance, but not much. The detail and instrument separation is very nice. The soundstage is on par for a $40 IEM.
Overall, the MA350s are a great pair of earphones. Nice bass with a punch to them, and a bright, sparkly Treble. A very good build too. Sightly recessed mids and annoying Cable noise keep these earphones from getting a 4 star review. If you need a nice sounding, portable IEM for around $40, the MA350s are a great choice. I would recommend them for just that.
