Hitting the Balance Point… ­ Which one? As many as possible! Happy Path: My personal history is that I rediscovered headphone listening in 2009, organized local meets, became the Ultimate Ears Ambassador to Head-Fi.org for a time, and now I get to work with audiophile gear every day at Massdrop. Not-Very-Audiophile Confession: What led me to Head-fi.org was spotting a cool-looking pair of shiny headphones on someone at an airport in Japan and wanting to buy a pair. I never did find out what that exact pair of headphones was, but I did find a great new headphone. My next super audiophile move was to…buy some HiFiMAN RE-0 in-ear monitors. Loved them but yanked too hard on the cable and lost the left channel. Shopping around for a replacement, I decided to try for extra bass since some people thought the RE-0 were a bit “bass-light”. (Bass insecurity is a thing.) I proceeded to overdo it by buying the Sennheiser IE8 (clublife) and then vowed to go for a neutral monitor. Not too bright, not too bassy, can I find “just right”??? Everyone who knows me in the community knows that I am a big Ultimate Ears Reference Monitor (UERM) fan. I got one of the first pairs as soon as they released and still love them to this day. Many of us think that sound signature is one of the very best and if you had to choose just one headphone or IEM, that would easily be a top 5 pick. The UERM signature plus some sub-bass is fairly viewed as a vision for the “perfect” reference monitor. But would that be the “perfect listening monitor” for most people? Many of us UERM owners have the desire for a complimentary IEM. One that is a bit more lush in the low end in addition to extending lower. We started this project with the goal of making the perfect reference monitor. We started with a base tuning similar to the Etymotic ER4SR and Ultimate Ears Reference Monitor. Then we looked to add the sub-bass extension. And we really wanted to keep the price to $299.99 so it would be affordable to more people. After a year and a half of experimenting, we got to the point where we achieved elevated but flat bass from the upper bass to the sub-bass with a very clear, flat, and connected midrange (except for a nice little dip in the annoying sibilance region and an extra bump in the presence region to balance the bass). We’re all at the Rocky Mountain Audio Festival in Colorado right now, where Jude Mansilla from Head-fi.org has organized a big CanJam event. As soon as possible, we’ll get some graphs up on the page. The graphs will show elements of today’s best monitors in the Plus frequency response and the sound has been subjectively described as very musical, clear and fun, with no annoying peaks. It’s a lot of sound, but I can turn ‘em up and not get fatigued. There’s rumble while watching movies but super clear dialog. This balance of driver characteristics, price, performance, technicalities, flat response, fun sound, and frequency range extension made us freeze this design. If you HAD to only pick one in-ear monitor or headphone, we hope this would be in your top picks…at any price.

Got mine today. Very small package. the case is small and fits the iems, ear tips and cable and cleaning tool. Very compact.
the iem has a very good fit. Small and very light weight. The cable almost looks and feels like a FIIO cable. Mor supple than the fiio one. Looks good, is comfortable to wear and nothing more to it.
The audio quality on this iem is outstanding. Massdrop has done an excellent job tuning this. I've CustomArt Harmony 8.2 CIEM, 64Audio U12, Rhapsodio Solar Universal & Heir Audio 10 Universal. This iem comes very close to all these TOTLs and at $300. Incredible!!! And this is out of the box. It will only get better after some burn-in.
Of course those TOTLs provide bit more resolution, staging etc. But I really feel that I'm not missing out on anything with Massdrop Plus Universal. Get a good DAP player and plug this iem into it - all set to enjoy the finest audio.
I'll try it with other aftermarket cables and see how the sound gets tuned some more.

My pair arrived today and the first thing I did was see if my 64 Audio cable would fit properly, and it fits like a charm! Braided cable with a right angle plug? Definitely prefer it to the stock cable.

Also for comply tips, it fits the 500 series if anyone was wondering.

You guys have basically come up with everything I've ever wanted in an IEM.
DF compensated? Check. Linear bass? Check. Flush fit with detachable over-ear cables? Check.
It's almost as if I designed this for myself. I've been wondering why such an IEM didn't exist already.
Thank you so much for investing the time and effort into making this happen. I'm sure they'll be a great set of IEMs for a very long time.

I bought these a little over a month ago. Just over a week ago, I messaged support about my included cable dissembling itself in my headphone port. As in, the tip came off the head of the jack and left me with what you see in the picture. No break, just...came apart. Anyway, I still haven't heard anything back. I did get an automated response saying it's been forwarded to the specialist team, but that was 6 days ago. I reached back out to helpdesk@massdrop.com today in hopes that someone would reply but I've got no response yet again. I'm sure I'm not the only one with cable construction issues. Bonus pic: My daughter rocking the HD6XX cans that I love and are my daily drivers when I'm not in the go :)

It's heartbreaking that these IEMs don't come with any options to purchase a spare cable or extra tips. Where do I go if I want extra OEM tips? These IEMs are Massdrop made, so where do I go to get a spare cable if something happens to mine? I want a spare cable (not the balanced one), and I've never heard of an IEM manufacturer that sells IEMs with a detachable cable that doesn't offer replacements for sale.
@CEE_TEE Where do I buy an extra cable?

I just received my pair a few days ago, and am pleased with these iem's so far. The build quality is very nice, and fit/comfort is down right fantastic with the right tip (I'm using the smallest sized spin-fit tip). The iem almost "disappears" after about 10 minutes of listening, and it's actually more comfortable than the CIEM's I have because I can move my jaw, and smile while wearing them without discomfort. Go figure. These will be great for traveling and long flights.
Regarding sound quality... I haven't spent enough time with it to make any definitive claims, but I think that people will feel they got a good deal for what they paid for. I have them paired with an AK70 MKII using the optional 2.5mm trrs balanced cable. The sound is nicely balanced, slightly on the "fun" side. Resolution is pleasantly surprising, treble is crisp and airy, but the mid-bass can get slightly grainy & flabby when pushed hard with some songs. Overall I think it is a very solid offering in the $300 range. It's not TOTL material, but it's about 80-85% there; and they hit it out of the park on the comfort side. Nice job Massdrop.
