Fostex th900mk2. The SJY carbon needs nuclear level power to get your money's worth. DCA has good planar bass but dynamic drivers are more bombastic. To me at least.

Hi folks! I'm looking for planar headphones for slam with good bass up to $500. Do they exist? I had experience with the stocked Fostex T50RP Mk3 and while I liked them overall for clarity, neither bass nor enough speed were there. Currently I use Fostex TH900 with Schiit Lyr 3 (Mesh with 6N8S), they are my reference for good bass. After some googling there are some potential candidates: * Fiio FT5 * Monoprice M1060C * Fostex TH500 * Audeze MM-100 * Sigva Audio SendyAudio Aiva * Fostex T50RP MK4/T60RP MK2 (but they are somewhat pricy and need modding) Anyone who has had experience with these headphones, please share your impressions. Or add your own advice. Thanks!

TH-X00 purplehearts with an Audeze LCD headband conversion for the clamp force Hands down my favorite cans for sub bass production. I own a pair of TH900’s but the purplehearts with that headband still takes the cake 👍 I’ve tried just about everything except for most of the recent ZMF headphones.

I had/borrowed the original Aeons and the RT ones (which have just a pad swap i think?) and to me they were anemic in the bass that was impossible to EQ to my liking. Pretty nice imaging and nicely isolated. Which is why i got myself some Aeon Noire X's, they fix the issues i had with the older ones and sound amazing. Although i am looking to sell them, since i prefer my th900 just a little more

With the dcas you can remove a screw to reduce the clamp force Th900mk2, and the aeon noire x currently. Am on the hunt for a good hd800s/8xx though to have an open alternative

If you can find a pair the Campfire Audio Cascades are my bass canons!! They smoke my Arya Organics, Celestee’s, TH900’s, Atriums, etc… When it comes to Bass!!!!

Curious if anc wasn’t a factor how they stack up to the Maxwell with sound. Being a bass lover but not at the expense of a muddy mess on everything else, these have been interesting. In general I don’t like most senn headphones because I need my bass, but I also need some clarity too. Use TH900 mk2 since I’m not trbek sensitive and SJY HCC at my desk but would like a decent pair for on the go that’s wireless

I love my LCD-X I’ve seen the recommended in this discussion a couple times but for me I prefer my SJY HCC and my TH900 mk2 for metal over them. The TH900 mk2 with the anniversary tuning is my favorite for it.

I’m not treble sensitive at all, but the anniversary tuning is a lot better than factory. I wasn’t bothered by any of the beyer stuff either. Oddly enough the LCD-X has some thing in the upper mids or lower treble that I am slightly sensitive too, haven’t pinpointed it though

Have to also factor in price, and what they will be used for. Do you want immersion, or laser sharp imaging? Do you find really wide soundstage to be better, or massive impact bass from explosions? The buy in is huge because the amp cost is a big factor but for me the SJY Horizon closed carbon with a bass shelf give me a ton one impact, a pretty wide open sound for closed back, laser sharp imaging. There are several times when I thought I heard voices or sounds across the room from the cats knocking something over…. Then find the cats asleep and realize it was from the headphones playing subtle details and throwing them out there really well. LCD-X were also really good but very very open. My Fostex TH900 mk2 need a little eq but the slam is insane for certain games, not the best for imaging though, not the worst either just not the best. Cheaper version of that impact is going with something like the Eris. If you really want some great imaging for the price some of the sennhieser stuff is great but you can’t really get much impact out of them.

I was actually going to say those FT1 seem to do a good job for those old rock type recordings. I like my TH900 mk2 when EQed more but damn for the price the FT1 are great at that.

I like some bass as well, but find I need to EQ a bit on any headphone I buy The SJY HCC would be my first choice, but you need a solid amp to push them. I added in oratory’s XBASS replica to EQ, other than that the turning was near perfect. The Fostex TH900/TH910 can really slam some bass. The treble is a little sharp but nothing some minor EQ can’t fix. For an open back solution the LCD-X the 2021 has a slam and punch I really haven’t found in another open back.

I also second having detachable cables. Aside from having to fix the cable yourself, you're also stuck with the fixed cable that the company chooses. Some cables are just plain awful; for example the fixed cable version of the Fostex TH900 is super long, heavy, and stiff.
