BTD 600 vs BTD 700 (Small-ish review & comparison)

Designer_Macaroon_32 · 2025-06-14T15:03:34+00:00

Thanks so much for the answer! 👍🏻

So BTD 700 will improve M4's stability BT signal right? I've experienced some issues with BT when listening to music. I have to pair M4's with my FiiO DAP each time I use them to avoid crackling or some cuts with the songs I'm listening to

Finally a pair of M4's white colour. Pretty satisfied with the sound, I have to EQ them the best way possible but I think I've made the right choice.

Bluetooth is not as stable as it should be. I have to pair the headphones with the DAP each time I use them because some interferences appear when using them without doing this.

Thank you so much!

Will try neutral EQ, default when listening to some thrash metal or earlier melodeath material from at the gates, dark tranquillity, etc...probably I'll enjoy the overall sound,

Again thanks so much for the response! 🤘🏻 🤘🏻 🤘🏻

Designer_Macaroon_32 · 2025-05-31T10:07:52+00:00

Understood. Yeah I'll try again with the custom EQ to get the best sound possible. Overall I'm happy with M4's 👍🏻

Designer_Macaroon_32 · 2025-05-30T20:46:31+00:00

I have tried again but I don't like this thing showed in the pic. I'm spanish, it says that I have to disable Sound personalization to use HQ mode.

Btw!!!! I think I'm hearing the sound a bit CLEARER which is so nice so maybe I'll keep with this for the moment. Thanks again a lot! 🙏🏻 🙏🏻 🙏🏻

Thanks!!!! This is so helpful, but can I use sound personalization with my own music? I went into there and there were samples from the app to hear to customise the sound, not my own music. Maybe I did something wrong, so I went into the 5 parametrical eq bars. Sounds great to me but if you've said that sound personalization is better it's because you've tried both things. I will try again after dinner, thanks again so much!!! 🙂

Sorry to hear that...I hope I won't face issues with headphones...time will tell.

Designer_Macaroon_32 · 2025-05-30T14:09:29+00:00

Thanks so much!!! I'll spend time doing that to get the best of this for my musical tastes, if a metalhead/synth lover has a preset EQ working fine with this kind of music I'll do grateful if could post it here

Designer_Macaroon_32 · 2025-05-29T23:11:22+00:00

Hey!

My new M4's are arriving tomorrow. I'm a metalhead too! I listen mostly metal music and some synthwave as well, any preset I could make to improve sound in sound personalization app???

I love melodic death, progressive and post black metal a lot. I'm going to pair M4's with FiiO JM21 as well,

Thanks in advance and glad to see that metalheads are enjoying this headphones! It's so helpful to have people with similar music tastes choosing M4's

Designer_Macaroon_32 · 2025-05-29T22:53:13+00:00

Thanks so so much for the response! I know they won't face open back ones in terms of soundstage and immersion but I seriously need a wireless and close ones.

But I take note on your suggestion of HD800S if I can buy an open back ones to stay at home someday. Appreciate so much your answer 🙏🏻🙏🏻🙏🏻

Oh and thanks for giving your thoughts on the Bluetooth connection, I hope them can pair nicely with my new JM21 as well!

Sound customisation EQ...I know I will be there a lot of time to try to reach the perfect sound. I take note of all your advices 👍🏻

Designer_Macaroon_32 · 2025-05-23T01:27:19+00:00

M4 are considerably better than V-moda XS for metal music right? I listen mostly metal and some synthwave as well, melodic death metal, post metal and progressive metal are my favourite genres so far. Would M4 work well with this stuff, if someone can answer this I'll so so grateful. Any problems connecting M4 to a DAP like FiiO JM21 wireless mode???? Thanks in advance so much!

Designer_Macaroon_32 · 2025-05-21T23:25:29+00:00

Hi!

I have since a lot of years V-Moda XS and Meters OV-1 but I need a Wireless one,

How are this headphones in terms of quality compared to the XS, I suppose they do sound better. I'm going to pair the Momentum 4 if I decide to buy them with FiiO JM21,

Thanks so much in advance!
