hi I'm Jerri Harvey from JH audio well gh 13 is a six driver three way actually is the world's first six driver three-way dulo dual mid and dual high it's in the 16 is the first eight driver three-way your piece which is four lows two mids two highs the main difference between those two earpieces is the audio signature in the Headroom the the 13 has more of a neutral audio signature very wide accurate frequency response out to 18 K but it has a sixth and the bottom end response has the 6 DB bump at 50 Hertz rows back down to accurate by 125 to 160 heard so it's very neutral neutral earpiece with a nice musical bottom the 16 was originally designed to be a performance piece because as 13 had about 3 DB less input sensitivity than the and that's it then then the 16 so that extra 3 DB of input sensitivity when you're in a live situation makes a huge difference especially when you're you know starting to overdrive the board a little bit through hitting a transmitter hard and you know the artist is driving a bell pack so sometimes you really need the the input sensitivity to get unity gain kind of all situated so you're not going above zero on your vu meters the the 16 is actually still a killer audiophile portable music earpiece because it's the many differences that's got 12 DB of boost at 50 Hertz and back to accurate by 125 to 160 it has the same mids and high extension of the same audio signature between the mids and highs as a 13 so it's basically a 13 with more punch so it's depending on your musical your audio taste you know how you like your bass set feel like a nice punchy bottom end with you know when the 808 sample said are the kick drum the bottom end or the kick drum you want punch on that you'll want the 16 if you're more of a jazz person you want something that's like perfectly accurate like an ear field set of studio monitors you'd like the 13 now both of those earpieces I've created a new thing called the Freak phase waveguide so basically the Freak phase waveguide what I've done is I've made the drivers all at the same time at the end of the ear canal within a hundredth of a millisecond which basically corrects the phase curve of the earpiece when you look at the the the phase curve of the 13 and the 16 they're no more than plus ten or minus ten degrees of face way off a zero or you look at most of the competitors six driver three ways the lows are sometimes almost 180 degrees out well and they do a nice level ski slope around one to two K where it's major cancellation and there are 90 degrees out on the highs so we've got a chart here that you can take a look at and kind of demonstrates that the the orange line is the is the 16 and the blue line is a competitor's six driver 3 way you can zoom in on that or you can do whatever you want what happens when the earphone has a very coherent phase curve is that the center image becomes very clean and clear and articulate anything between 10 and 2 is where the phase cancellation starts to really occur when you have an incorrect phase response and an earpiece or a speaker or anything else so when you have something panned hard right or hard left it sticks out it sounds like a really wide soundstage because there's not interacting with the other speaker and there's no cancellation but as you get towards mono the center image that's when all the cancellation occurs so between 10:00 and 2:00 you if with this phase this waveguide with a correct you know coherent phase curve what you end up with is very detailed articulate center image you have the ghost image of the vocal right in the center of your head and you hear in just you know five six three degrees of any kind of panning off center and you hear that and you you hear all this separation in the detail and you know very articulate layering of instruments and so the thirteen and sixteen are the only two earphones on the planet they're actually phased correct took me 16 years to figure that out so well I actually invented the hybrid technology back when I was the founder of Ultimate Ears and it was it was really kind of a good compromise back then because the dynamic had nice warmth bottom end and the and the the balanced armature at a point in time didn't have a whole lot of bottom end so it was a nice natural combination if you use the diaphragm on bottom and use a balanced armature on top but you know you have problems with diaphragms there they're one of the worst candidates for phase if they're phases all over the place and then there's no real Headroom or dynamic range they just stored really quickly so that's why I went back to balanced armatures and I started you know making double dual armatures and then quad armature so now I've got stuff that's going down to 10 Hertz the thing to do 130 DB and the low-end before it starts to distort it's got lots of dynamic range lots of lots of you know hot input sensitivity for live or listening to playback and it's a much more controlled body menu it's a very repeatable bottom and where a diaphragm if you change one thing about the volume are one canal is larger than the other then you end up at with a totally different frequency response from right here to left ear so even though Meniere's owns a patent and they're really the only only company they should be building a hybrid anybody else's infringing on that patent I choose not to even go down that path because I prefer you know I moved away from that you know ten years ago and decided that if I keep putting my you know pushing the technology forward on the balanced armatures I'm gonna have a very repeatable earpiece that has wide frequency response in put hot input sensitivity and you know dynamic range behind me you see the video of the company called land toast technology they've invented a 3d ear scanner currently if you'd like to purchase an in-ear monitor you have to get a silicone cast of your ear and impression so you have to go to an audiologist or come to our shoppers go somewhere where someone can actually do that process for you we have pretty good repeatability as far as fit wise you know about 90% but this is going to make it a hundred percent and the reason is that we do an open-mouth impression so 80 percent of the population when you open your mouth that canal expands but 20 percent of the population when you open your canal that can open your mouth that canal restricts so most of the problems we ever have with the fit issue is the 20 percent factor that the canal is actually in verse when they open their mouth what's nice about this scanner is that it's very very accurate and you can actually see the dynamic range if you notice there's a point in this video where the you see the patient opening and closing or her mouth and you see how the actual ear canal changes shape and it's amazing how much an ear canal changes shape it's a huge breakthrough and it's going to be a you know much easier to get impressions start in first quarter of next year
