i've been curious about these headphones for a few months now. recently came into a bit of money so i'm seriously considering them.
however, i do have a different set of cans which altogether come to almost as much cost, and as i'm in the uk these would actually cost me $480 rather than $400, so i do have a few questions.
first, i suppose i should give my current headphone context. i'm using an aiaiai tma-2 with the h05 aptx headband, the s03 driver units, and the e05 microfiber cups. i was using the PU leather cups for a few years until recently, as the "leather" started peeling away where my glasses rubbed on the cups. to its credit, it felt more like bonded leather than PU leather, although of course that's still very far down the leather totem pole.
i understand some of the tma-2 speaker units don't have the best reviews, but those are almost exclusively s01 and s02. at the time i ordered these about 5 years ago, s03 had the flattest response curve in the configurator, and more recently their s05 unit has also had decent reviews for being $300 headphones.
the main reason i being all this up is i would already describe the soundstage as wider than most closed back, and being somewhere between closed and open back, as many have described the pandas. there's no fancy THX amplifier or ribbon driver, which is what is drawing me to the pandas. but certainly bass isn't overemphasized, while still being present when the mix demands it. the mids have decent room to breathe, and the highs are fairly crisp without being grating. again, this sounds broadly similar to the descriptions people are giving for the pandas.
the chip in their h05 wireless headband is the qualcomm 8675. qualcomm themselves claim 8645 but everywhere else says 8675. it certainly was noisy when i first got the headband, but there was an update a few months ago which boosted the mic volume and drastically reduced the noise floor.
the main ways that i'm growing dissatisfied with this setup is that the microphone is still pretty poor. phone calls are intelligible now (i was inaudible before the update) but google assistant still takes a long time to decode what i say through the headphones. some people say i sound far away speaking through these headphones, as if i'm on speakerphone, although others say i sound the same as any phone call (i presume GSM sampling and bit rate has something to do with that).
i like that there's the wired option, again very similar to the way the pandas function. i'm not a huge fan of their 3-button-remote layout on the headband though, and the buttons while clicky don't move very much.
the biggest ergonomic gripe i have with this headphone is that the cups are fixed against the headband with no swivel, and the circular pads while looking nice in photos and the sketchbook end up causing soreness on the corners of my ears after a few consecutive hours. the shape of the panda cups seem like they would avoid that issue, though some other people have said the padding isn't good enough for prolonged use.
i did also own the tma-1 in 2012 and that headband wasn't padded enough, whereas the h05 on tma-2 is padded enough for me. so i'm slightly wary in case the pandas would be more of a sideways-grade than a strict upgrade, at least in terms of the ergonomics rather than the sound. (i am presuming the pandas would sound better to some degree or another, even if the quality of the sound signature is similar – which is fine by me as i like that kind of sound and specifically picked the s03 as having the flattest curve out of the 4 options they had at launch)
i'm wondering if anyone would like to chime in with their experience wearing the pandas for long periods of time? i'm not opposed to shifting the headband slightly forward or backward periodically, and i do like that the cups have independent swivel on the pandas a lot. when i do listen to music on headphones i tend to do it all day, so this is rather important to me.
the functionality seems to be basically identical in terms of input options, since i also have the USB-C to 3.5mm cable aiaiai sold. and that's important to me, so that i can easily plug into my various synthesisers and my USB audio interface on my computer which i use to record mic, guitar, sax, etc. besides one or two people who had analogue audio sounding flat, most people report it sounds basically the same via analogue, USB, or BT, and that's also important to me (and also is the case with my tma-2 configuration, when the analogue input is powerful enough – a laptop's built in output makes them sound slightly less clear).
apologies for the ramble, i guess i'm just trying to bring up all of the relevant details that make me like my current headphones, the relevant details that have had me looking at pandas for a few months, and especially i'm wondering if by a long shot anyone else here has used the s03 speakers and could possibly make a direct comparison? i'm presuming the pandas will sound better due to being another 33% more expensive, but i'm still just on the fence about buying an entirely new set of headphones considering the modular approach has served me well over the years. though obviously the cabling is modular oh the pandas also, just not the headband. and the always-circular ear cups is really starting to get on my nerves.
i would say i'm really rather satisfied with the sound of my current tma-2 configuration, and the latest update also reduced latency a lot. the headband already seemed to communicate latency back to the phone as netflix and youtube would delay the video by a split second after hitting play, but with the update even videos that were out of sync before are basically in sync. so seeing aptX HD latency is still kinda high on the pandas is another slight trepidation factor on my part. but i would also certainly be satisfied to get something that sounded the same but better. i tend to like to use just one headphone for everything, wired, wireless, spotify/soundcloud but also listening to FLACs at home. casual listening, but also dialling in sounds on my instruments. and i certainly am impressed by the various frequency charts presented here, and by people's descriptions of the sound that sounds like exactly the kind of sound i like.
so i guess... yeah. any extra analysis anyone can provide would help me a lot. especially because of how many people were saying they'd never experienced this much of a soundstage on closed-back headphones before, just has me wondering if the s03 is more special than i'd realised, because it also has that quality to it. or maybe i'd get the pandas and the s03 would seem crowded by comparison. that's the trouble with describing sound in words, i suppose. like, with my tma-2 configuration, i was aiming squarely at solid midrange performance without undue emphasis on bass. and the headband does use a DSP/analogue hybrid instead of pure DSP. but i have kept looking at and thinking about the pandas, because of their shape and design and planar ribbon.
so, please help me evaluate this! (which i guess means, convince me that it's worth spending $480 plus shipping on these headphones!)
oh yes, one last thing, the firmware on the h05 can be updated through fwupd in linux, which i really appreciate. and aiaiai host their firmwares on github. the idea of having to use a smartphone app that may or may not exist in ten years is less appealing to me. but that's about the only seeming downside, if the pandas are more comfortable than the tma-2. it's not like there's been a ton of firmwares released either, but it's just nice to know that they're hosted on github and i should be able to access all of that many years in the future if i needed. but given that the pandas use another qualcomm BT audio chip, maybe they're also theoretically compatible with fwupd? i'm not against apps to be clear, i just like there to be more than one update pathway.
also are the ear cups detachable on the panda? if this is like any other PU leather my glasses WILL make a mess of it after a few years, and it'd be nice to know i could replace them instead of just having tatty looking pricey headphones. that is one of the things that initially drew me to the modular system in the first place, and i did have my eye on the alcantarra ear cups aiaiai announced last year, though if i was to go ahead and order pandas i doubt i would bother – the microfiber cups are just fine. so yes, being able to replace the ear cups on the pandas would be really nice, especially if there ended up being velour/alcantarra options.
okay, i think i really said everything now! thank you for reading all of this if you did! i scrolled down through all the comments as best i can tell, and tried not to ask questions that others had already answered in their posts, but apologies if i missed yours.
thanks for being such a great community, audio massdrop!
