    CanJam @ RMAF 2017 (October 6-8, 2017) Impressions!

    First off, thank you Head-Fi family for such a warm welcome to CanJam and the community as a whole. This has been an awesome experience for both me (the product guy) and Andrew (the acoustical mad man). We are finally here! I’ll post up some photos tomorrow but you can pre-order the HP-3 now...

    Of course! The first Alpha-build is happening in June, which may not be Prime-time ready, followed by the beta-build a month or so after. All the metal parts take about 6-8 weeks to tool (cutting steel), that's why there's quite a big gap between now and then. I'm hopeful to hit the road late...

    Sorry guys, it's been a very busy few weeks preparing for kicking off tooling and getting everyone's input and sign-off. That being said, we're off to the races! The mechanical design of the metal yokes and attachment mechanism proved to be our first challenge, which we overcame without making...

    Sorry I've been on hiatus briefly. Between the travel to Japan followed immediately by Texas this is my first week back in some time. We definitely missed out on CanJam NYC this year as our small team was all overseas during the time. I hope everyone had a great time.   Drivers are recessed...

    We had an SLA mock-up of the headphone stand done and will test the design to make sure it doesn't warp the headband. You don't have to worry about the flagpole effect as the tolerance for the rod and the socket will be controlled tightly. In other words, if the hole is + 0.01-0.02mm of the 10mm...

    Yes, most definitely. We initially wanted a modified version of the Fostex HP-A4BL, but it lacked any analog in/out so it required heavy surgery. We determined that the scope was starting to creep and the redesign was counter-productive. Instead we chose to do our own ground up design. I think...

    We will definitely be studying what happens after the headphone rests on the stand after an extended period. I definitely don't want to deform the headphone either.

    One more update for you guys - here's the preliminary rendering of the headphone stand that we're planning to include in the package. The copper piece at the base is intended to function almost like a screwdriver socket. It's magnetic and the bent steel (10mm) rod will magnetically attach to the...

    This picture should give you an idea of what the cabling looks like. Above the yoke you'll have 4 conductor twisted pair with a smoked semi-transparent TPE jacket. We're going to go with 4 conductors and then combine them together at the 3.5mm. If we use 2 conductor cable it'll be the same...

      Your voices have been heard. After getting your feedback I quickly changed the materials of the box from birch plywood with walnut veneer to MDF and a vinyl wood finish. I figured it will still look the part, be more rugged, and in turn less "exotic". It'll cost quite a bit less but still...

      I really want to include a balanced cable but I think at the cost this one's out of the picture. You'll get a single ended-short (1.37m), a single-ended long (2.5m), and a 1/4" adapter. No microphones to speak of. Also, keep in mind that the "attach-rate" for balanced cables is less than 50%...

      Here's what we did - I wanted a press-fit 1/4" adapter to fit over the 3.5mm plug and I wanted it to be universal. So, the steps go like this from top to bottom:   1. 3.5mm plug (3.5mm OD) - minimum diameter 2. First step (5.95mm OD) - this is Apple's spec for case manufacturers, this...

    I think regardless of what we do there will be a big discussion about the sound, as there's no one-size-fits-all product for anybody. After we evaluated a slew of drivers (note, drivers, not headphones), we found the biocellulose Foster drivers to be amongst the best in a number of areas.   I...

    Yes, Paul W. Klipsch made a modified headphone in 1919. It started as a Brandes Superior telegraph headphone, made in New York. Paul then tinkered with the drivers to make them sound good for listening to music while wiring them for balanced stereo with a pair of lamp cords and some 1/4...

      I think the push-pull connector is honestly the best solution. 3.5mm is even better but the problem is they tend to either snap entirely (under force) or become loose over time and are easy to tug away from the headphone the moment you catch the wire with your hand. The weak point is always...

      I love Head-Fi because most of these questions sort themselves out. :)   To your point, yes, the flagship has two wires while the others will ideally have just one. Of course the wireless models and ANC models will require a single cable. I love the convenience of single-cable but the...

    I like all the back and forth about the sound signature. To shed a little light I'm going to paint a bit of a picture for you - I really enjoy comparing the inherent differences and properties of a good two-channel listening setup and a pair of headphones. As a matter of fact, that's one test I...

    I'll try to answer a number of questions after saying a big thank you from the Klipsch crew. We're all scribbling down ideas and it looks like the Head-Fi community is pretty much on point with the necessary accessories, the key issues of contention, and the aesthetic.   - The LEMO connectors...

      If I have the choice of being able to drive this HP-3 with a portable device (basically anything running off a 3.7V lithium battery) or driving them with OTL amps, we would likely choose portable devices over the latter. However, there's no reason why one headphone can't do both in most...

      This one's a bit hard to answer since they're quite different animals. Personally I think the X10's bass tends to creep into the midrange a bit to much, so the HP-3 will have ironed that out. Next is the X10's high frequency response, it rolls off faster than our X20, so the HP-3 will have...

      Loving this thread guys. My name is Vlad and I'm the product manager behind these beauties. The feedback is great and I think a lot of what we're talking about aligns. Now, to address a few things:   Comfort: All of you are spot on - from the entire category of premium headphones it's...
