I was wondering, are there any portable dac/amps planned that use USB power deliver 2.0  through USB-C?   20V/5A would allow a portable device to drive any headphone in existence and with power regeneration onboard that would be the end of needing AC powered headphone amps and dacs.

So, can you take the HD800 lemo connectors and the 4 pin XLR off the stock Sennheiser balanced cable cleanly and reuse them?  Or are they glued ?  

By fixed I mean no more 6kHz peak, no easy paint chipping and a matte black option.

Hello!   After I broke the microphone of my Sennheiser HME25-1 and then I sold it without, I needed another headset, so I got another top headset -  the Beyerdynamic Manufaktur MMX 300.    Now my first impressions using the included usb soundcard -  it's somewhat better compared to my...

The crappy hd201 cable finally broke, and I want to recable them. I dismantled the headphones but I don't know how to take out the driver from the frame it's fixed on. There were screws but I took them out, and the driver assembly is still fixed to the frame ...

I was browsing the RME site looking for the HDSPE-AIO and what do I see: This thing looks like a laundry list of features: 22-Channel 192 kHz multi-format mobile USB audio interface 10 Input / 12 Output channels 2 x analog I/O with mic pres, line and mic level, balanced or unbalanced...

Are these guys lying? Standalone Converter

By that I mean: 1. Does it have four separate wires? 2. Is the wire thickness/type the same as my hf2's? If it's like the old sr80 cable, then what kind of wire is good for grados? I would prefer personal A/B impressions, not hearsay.

What are my options? Hybrids are ok too. Maximum 500 euro.

Here's a battery powered amp that's fully discrete, and I was wondering if anybody has heard it: Welcome to Scherzo Audio - Home of the Andante Headphone Amplifier. Scherzo Audio Andante Headphone Amplifier Description: Rest assured, this is no glorified "op-amp-in-a-box". Build quality...

I was thinking: If it's possible to make a multi-hundred watt class AB speaker amp completely battery powered (see the ASR Emitter's 26kg psu here), making a desktop battery powered PSU for a headphone amplifier would be much easier since the power requirement is a small percentage of that...

I have a pair of AKG K28NC headphones, and I managed to break the little nub that goes into the driver housing. I was thinking of buying a K26P or whatever it's new name is, to replace that part, but I can't disassemble the headphones ... I want to extract the broken part from the driver...

I recently bought it online, and it arrived like this: Is the driver the original driver of the AKG's ?

Let the reference be the px100 ... I mean the bassiest open headphone besides PS-1, my budget does not stretch that far ...

I'm considering investing in a new audio setup. I'm getting either a 0404 or a firewire audiophile, and a morgan jones tube amp. What are your experiences with this amp? Especially with the Grado SR80, but also with HD580, HD595, DT770pro or A900 ... if anyone heard these combos. Edit...

After the successfull thread about the 880's I think it's time for the 770's. The true nature of a headphone can be revealed by listing the bad traits. Please list the reasons you sold this headphone, does it have fast transient response, is it sibilant, does it have a low midrange, is the...

I can get these for 100 euro ... I always wanted some wireless headphones. If they are at least on par with the hd201 .. I'm thinkin of getting them.

I have a pair of Sennheiser HD201, and I find them not quite efficient, slightly bright, connected to a SB Live! 24bit. I'm thinking of selling them and getting a hd205, but only if hd205 is more sensitive! So. are they. How would the 205's compare to my 201's?

Previously I had a Sony P180 (flabby bass, good soundstage, honky but fun), a Grado SR80 (fast bass, detailed, too bright, not circumaural, low comfort), and now I have a Senn HD201, as a stopgap headphone (slower bass than the SR80 - not deep enough, not honky - despite being closed, not that...

http://www.audiotrak.co.kr/zeroboard...udiotrak&no=19 What do you think? It seems to have better op-amps (opa2134 and jrc5532) and the same color as Julia. Still WM8770, but that's not such a bad thing.
