is this a scam or a legit sponsorship??

Their website looks pretty legit and they're offering to pay before they proceed, plus their email ID looks legit as well, i've pasted the email below:

Hi creator *my channel name btw*,
SoundEQ (https:// soundeq. ai) is basically our attempt to get rid of the one-size-fits-all sound. Instead of another EQ with presets, it uses Ai to learn your hearing quirks and taste, then builds a personal audio profile and reshapes everything you play on the computer. Music hits different, movies suddenly feel balanced, games pop out more. People test it once and usually go “oh, I didn’t realize my sound was off until now”. Right now it’s built as a desktop app - works on both Windows and macOS.

Before we dive into collab formats, it’d mean a lot if you check it out yourself. You can grab the app for Windows or macOS (it installs in a minute). Easiest way - just type SoundEQ  into G o o g l e , it’s right there on top. Once you’ve got it, run through the quick signup inside and confirm your email.
To move forward seriously, just shoot me either the email you used to sign up in the app or your UserEQ ID (you’ll find it inside the app under Settings → My Profile → UserEQ, looks like se_userid_xxxxx ). Once I see that, I can unlock full access for you and we’ll immediately step into the practical part - contract, pre-payment, content planning. If it’s easier, feel free to drop it to me directly on Telegram (handle’s at the bottom of this email).On the business side, we keep things simple. We handle payment upfront in full, before your integration goes live - no waiting around.We also run a referral program: every subscription that comes from your audience adds extra revenue on top of your flat fee. It’s basically passive - stacks quietly in the background while your content keeps living.
Payment methods - bank transfer, PayPal, Wise, or crypto if you prefer. If you’re in a VAT jurisdiction, we’ll handle the paperwork so you get the net amount agreed, no hidden fees.That’s why we’re excited: it’s not just a typical paid collab, it’s also a chance to be in the first wave of creators tied to something new in audio that people actually feel the moment they try it.
*my channel name btw*, to give you a sense of where we usually start with partnerships, here’s what we can put on the table: ' Shorts / Reels / TikTok: around $600 per post' Integrated segment inside a video: $900 flat' Full video integration: case-by-case, depends on reach and ideasAnd if you’ve got your own spin on how to show it off - we’re all ears.  Also attaching our SoundEQ ResourceKit PDF - it’s a quick dive into the brand, visuals, and positioning so you get a feel for how we present ourselves.
Curious to see what you think once you’ve tried it - most people end up showing it off to friends before we even get to talking business.

Cheers,
Markus
