Thanks! They are set to be delivered from January 27-30, so I'll be sure to do my initial impressions with them around this time (if they come on time, that is). Unfortunately, there were no other options for shipping speed besides the free shipping, so I'll just have to be patient until they come. I have very little hands-on experience with headphones in general, but I'll make sure to be honest with my thoughts.
Need help choosing a pair of IEM's ($120-$180) that are good for all genres, mostly electronic or... - Page 2
Yeah, it seems like once you enter audiophilia, it's hard to go back. I've never experimented with burn-in, but I believe in the theory. I'll be sure to burn-in these IEMs, but first I want to listen to them out of the box so I can see (or hear) the difference after I burn them in for 50+ hours.
The Apple Earpods are HORRIBLE with noise isolation. Obviously they weren't made for that, but it's hilarious when I have them in (while listening to music), and I'm still able to hear subtle things like a pencil writing on paper.
I guess Amazon liked me this week, because I've already had the RHA MA750i's for about a day now (got them just before the weekend). I was pretty excited, of course, and once I was done opening the package, I was amazed at the quality of packaging. And wow, just look at the headphones themselves!
They come with what I believe is a clothing clip, a bunch of extra tips in a metal tray, a booklet about the headphones, and a nice (but partially over-sized) carrying case.
As I said earlier, I wanted to see what these sounded like out of the box so I could compare that to what they sound like after burn-in. Well, I shoved them in my ears (with the stock tips) and I made the mistake of putting on a song that wasn't mastered correctly. The highs were so harsh that I had to pull them out of my ears. There are many good reasons why that happened, however: 1) My source was an HP laptop, which certainly is not the best in the world. 2) As stated before, the song was pretty treble-heavy and wasn't mastered correctly. 3) The test was out of the box, with no burn-in whatsoever. 4) I've heard that the treble is usually extremely bright with the stock silicone tips in.
As of now, these have about 22 hours of burn-in, give or take 15 minutes. I took out the silicone tips about 10 minutes ago and applied the memory foam ones that come with the headset. I've heard that the memory foam tips are best for the 750i's, as they greatly reduce the harshness of the treble.
I inserted these in again, and the sound quality is definitely improved. I'm definitely not an expert with headphones in general, but the harshness of treble disappeared (in most occurrences) and the overall quality of sound was improved. I like how fast the bass is, giving a proper thump at the right moments without bleeding into the mids (at least that I know of). These in-ears get get extremely loud, too, without any noticeable distortion whatsoever.
As for the build quality, these things are built like a tank. The cable is very thick, which is well appreciated. Also, the dividing part (I have no idea what the name is, but it's where the cable splits and forms a Y), headphone jack (which is utterly beautiful, by the way), and the headphones themselves are made of metal. To top it off, the added 3-year warranty gives me peace of mind.
The stock tips didn't fit very well, but I think they were just a little big for my ear canals. The memory foam tips are much more comfortable, as they can kind of shape to my ear canal.
I'll do some more burn-in to come with a conclusion.
