I need a pair of noise ANC wireless over the ear headphones (iems do not work for me, so the TWS models are out). I am looking at the Bose Quiet Comfort 45 and the Sennheiser Momentum 4. I have semi-Dumbo ears, so the interior size of the ear cups is vital. Does anyone have the interior...

What I am looking for is a small passive device that would take a 4.4 balanced headphone output and connect it to two (or three) balanced headphone cables. So, one 4.4 socket that would switch between one or the other of 4.4 sockets. Passive (no power needed) and balanced, capable of using 4.4...

I am contemplating a major project, but I am looking for advice before I begin. Several years ago, I ripped my extensive CD collection (pop, rock, classical) to FLAC files. When I purchase downloads, I always purchase FLAC format, usually 44.1/16, but some are 24 bit. I listen exclusively via...

I know that somewhere on Head-fi there was posted a description of the filters included on the K9 Pro (i.e. which filter works best with which genre of music) but for the life of me I cannot find it. Could someone point me in the right direction? Thanks!

Is there an easy way to tell if a FiiO K9 Pro has the AK4499 DAC chip, or the ES9038 DAC chip, short of disassembling the unit? Serial number range? Any other model designation on the back or base of the unit? I that, due to the AKM factory fire, only a limited number of the units were...

Anyone with experience using the iBasso DX150's line out.... should the unit's volume be set at the max (allowing the amp's volume control to control the sound level)? This seems to drain the battery really fast. Alternately, set the DX150's volume, say, mid way and increase the volume on the...

I really like my DX150, but I find that iem's tend to hurt my ears after a while. (I have tried many different ear tips to no avail.) So, for reasons of comfort,I would like to use the DX150 with an over the ear headphone. Currently I have the Amp 6 module the DX150 came with. Would the Senn...

OK, here's a question on fast charging for the DX 150. Right now I am using a 5 watt 2.1 amp wall plug charger and it take a LONG time to charge the DX150. The (brief) owner's manual says the unit supports fast charging protocol PD2.0, but does not give a wattage. I have a choice of two USB-C...

I'd like to pick the collective hive mind for a bit... I need a new DAP. I am getting more confused than enlightened as I read reviews, so would like some suggestions from folks who have had direct experience. My 'musts' are: 1. Reasonably uncolored reproduction (I know this is a matter of...

I currently have a Marantz 5004 CD player directly  feeding my Stax SRM-323, which drives my Stax 507 earspeakers.  I am in the process of ripping all my CD's to flac files, and will purchase only hi res digital files in the future.  My question is this:  what digital source would be best able...

I recently bought a used Stax 323s amp/'driver unit' (thanks, Mike!) to upgrade my Stax gear, and have been listening a lot. I thought I would share my impressions.   After a very pleasant morning listening to a variety of orchestral and vocal music along with some 60's-70's rock, the SRM-1...

I am considering a pairing of a Schitt Valhalla with a pair of Sennheiser HD600's.  If anyone has this combo, or has listening experience with it, could you comment on how they work together?  Would the 650's be a better choice?  I listen mostly to classical, with some 60's-80's rock tossed into...

I'm a new member.  I've been doing a lot of reading here, searching through the forums.  I'd like to ask the collective brain a question, but first a bit of background information.  Because of neighbor/noise issues, I listen exclusively via headphones.  I listen mostly to classical, but also to...
