Just mustered up some change to get myself some The MEZE 99 classics, and altho I know the wired quality is much better, I do walk around with my headphones on (even not playing anything just as habit).

for starters, i want it to be bluetooth (or wifi) whichever is better quality, if possible both, so i can use wifi on my computer (not to lose quality) and Bluetooth on my phone.

second option that i really would like to have more than anything is that i want to be able to hotswap batteries. i even got some very shitty steelseries headphones just because they have that option. I want to be able to charge one battery outside of the headset and have it ready to swap with the one inside the headset the moment it is low.

and the third thing is that i would like to make it not look like im wearing a bomb on my head. the sleeker the better.

I am into a lot of DIY so I'm open to any sort of 3d modelling for extra equipment on the headphones. 3D printing and such are on the table, i do know how to solder but i dont know much about circuits.

TLDR: i need options to make MEZE 99 classics wireless while not losing a lot of quality and having hot swappable batteries.

To my knowledge, you don't use wifi the way you think. You only use Bluetooth. What I can think of is buy a short cable that fits the Meze 99's. Ali express has short cables at .5 meters. Then buy multiple Qudelix 5k's to hook up to the short cable and there's your hotswap capability. Or you can use the regular cable and put the Qudelix in your pocket. For longer battery life you can get something like the ifi xcan. Or maybe you're really good at diy and can do something with a tiny version of raspberry pi. Then you plug into that and then you would get wifi going to the raspberry pi.

Not a bad idea actually! Would get better audio with the pi, it just needs more power. I might try to get a pico working if at all possible. I want to make it so that its just the headset and nothing extra. So like no connection to pocket or anything.

I like to clip the Qudelix to the headband of headphones. You'll have to find a way to attach it to the headband. A short cable will suit your needs for that. You can make a diy short cable if you can solder. You can even use the Meze cable to do it. Good luck and post your results!

Just found out qudelix doesnt sell in canada. (Sad times)

[–] yellowmnm@alien.top 1 points 11 months ago

Try to look for the Earstudio ES100. It's similar and good enough for the brand Spirit Torino to sell with their headphones. If not available, maybe we can work out a deal for my Qudelix.

You don't need to mod anything. Just buy a BTR5, BTR15, Qudelix or one of the other Bluetooth DAC/amps. They have internal batteries that last a long time. The 99s are easy to drive so any of them will work, but a balanced cable should make it sound better. You don't need one for the Meze though.

Any of the Bluetooth amps can connect wired or wirelessly. They can handle LDAC if you want lossless.

Wow nice! Ill look into those, thanks!

[–] Ophanil@alien.top 1 points 11 months ago

No problem!

Try Qudelix 5K or any Bluetooth amp/DAC dongle.

Qudelix 5K and other dongle info: https://www.reddit.com/r/HeadphoneAdvice/comments/17zjxp6/looking_for_desktop_dacamp_gaming_budget_250_aud/k9zw9b6/ and https://www.reddit.com/r/HeadphoneAdvice/comments/13a1rdm/noisy_amp_in_new_apartment/jj4y67a/ and https://www.reddit.com/r/HeadphoneAdvice/comments/136sxe8/qudelix_5k_vs_khadas_tea_vs_btr7_with_iphone_and/jir8k23/


Or FiiO UTWS5 + adapters/converters for your Meze 99 Classics/particular headphones plug + KB9P AptX Adaptive USB transmitter dongle. If you're using iPhone/Apple/etc. make sure to get an OTG (allows data transfer) adapter/converter for the KB9P/etc.

See here for more info on how to use the UTWS3/5 with headphones instead of just IEMs: https://www.reddit.com/r/headphones/comments/109gr1t/here_is_the_follow_up_post_of_the_hd_660s/j3yngj0/?context=10000 and https://www.reddit.com/r/headphones/comments/109gr1t/here_is_the_follow_up_post_of_the_hd_660s/j3yq4vs/ and https://www.reddit.com/r/headphones/comments/1095ijp/i_made_a_pair_of_bluetooth_adapters_for/j408j33/

There's also the LC3 and AptX Lossless transmitters/dongles available now from Creative Labs (check their newer headphones, TWS/Bluetooth stuff)/random Kickstarter projects/but unfortunately they're like double or way more expensive than the ~$15 KB9P dongle.

And at the moment, there's essentially no LC3/AptX Lossless/etc. TWS adapter yet. Like there's the QCC5171/5181/etc. neckband adapters that have been out for several months now, and they're only $50-80, so worth a try, but they will probably have more static/etc. issues though.

Here's more info on TWS adapters like the FiiO UTWS3/5, KZ AZ09 Pro, etc. alongside adapters/converters, AptX Adaptive dongles (KB9P, YET-T10P, etc.), and so on needed for them: https://www.reddit.com/r/headphones/comments/11xmti7/unpopular_opinion_i_do_not_enjoy_qudelix_5k/jllhw46/ and https://www.reddit.com/r/HeadphoneAdvice/comments/13sbx39/aptx_vs_aac_on_mac/jlp72pk/

I forgot about the fiio utws with adapter for 3.5mm option. I considered it before. Nice.

There's also this that you could adapt to the meze's https://youtu.be/zNHDbXAmY_0?si=FuhRQ40rCtbVXIZR
