In gaming, every day is unpredictable, with new opportunities and challenges. But in all the unpredictability, there is one constant that gets you to victory – the META PICK. For us, the MMX 300 PRO is the META PICK that offers professional sound for professional plays.

  • Professional studio sound with gaming tuning
  • Unique speech intelligibility thanks to high-quality condenser microphone

  • Earpads, headband and cable as replacement parts
  • Made in Germany

PROFESSIONAL SOUND FOR GAMING

The STELLAR.45 driver, also used in our studio headphones, allows you to hear even the smallest sounds while you're playing. Thanks to the closed design and unique wearing comfort, you can fully focus on your gameplay and communicate all the important details clearly with the full sound of the microphone. Experience the maxmimum of professional sound optimised for gaming with the MMX 300 PRO.

POWERFUL ON PC & CONSOLE

Thanks to the low-impedance STELLAR.45 driver, the MMX 300 PRO can used on all devices such as PC, PlayStation, Xbox, and Nintendo Switch. Operation on consoles is ensured with the Y adapter, which comes together with the headset.

GAMING WITH STUDIO SOUND

Experience the third generation of our famous gaming headset: the MMX 300 PRO. The STELLAR.45 driver with gaming tuning ensures professional sound at studio level. With its balanced highs, mids and lows, the MMX 300 PRO shines in all game situations. When gaming, for example, the atmospheric music in the game is emphasised in the depths and the in-game sound localisation is accurate down to the smallest detail. The highs have also been refined by our acousticians, ensuring music enjoyment outside of gaming as well.

SPEECH INTELLIGIBILITY WITH A PERFECT SOUND PROFILE

Clear voice transmission can be crucial in some gaming moments. We know this. That's why we drew on our many years of microphone expertise to get the most out of the built-in condenser microphone. Every shot call is true to the voice and simply pleasant. With the extended frequency range from 20 Hz to 20,000 Hz, the highs and lows are particularly precisely balanced.

UNPARALLELED WEARING COMFORT

The combination of design and comfort makes the MMX 300 PRO the perfect gaming headset for demanding gamers. The new design is characterised by precise edges, an improved design language and maximum ergonomics. To further optimise our proven wearing comfort, we have added a fontanelle recess and a convenient snap-button closure to the head pad – features that can also be found in our studio headphones. Because maximum comfort is essential: not only in the professional studio environment, but also in extended gaming sessions.

HANDMADE IN GERMANY FOR A LONG-LASTING GAMING EXPERIENCE

We have been known for our audio products “Made in Germany” for a century. The MMX 300 PRO is no exception. With high-quality materials, careful workmanship and a spring steel headband core, the headset is designed to be used for years. This is also where our service comes in: We offer earpads, headband and cables as replacement parts for many years.

Great for recovery
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
Really helps with post work out recovery. I feel noticeably less sore when I take this after a workout. Definitely prefer the lemon flavor over the berry.

Great formula, but desperate for an unflavored option
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
I’ve been incorporating Thorne’s Amino Complex into my daily stack, and from a nutritional standpoint, it’s hard to beat. The clinical dosing of essential amino acids is exactly what I’m looking for to support my recovery and fitness goals. Thorne is usually my go-to for purity and quality, and this product is no exception when it comes to the actual ingredients. ​However, the flavor profile is a significant drawback. To be blunt: the flavors are just not good. They feel chemically and overly sweet, which makes it a chore to drink rather than a supplement I look forward to. ​I would much prefer an unflavored and unsweetened version. Having the option to just mix the raw powders into water or my own beverage without the unnecessary flavorings and sweeteners would be a game-changer. If you’re sensitive to artificial tastes or just prefer a "cleaner" experience, the current options might be a struggle. ​Pros: ​High-quality amino acid profile. ​Trusted brand with great sourcing. ​Cons: ​Flavors are unpleasant and too sweet. ​No "naked" or unflavored option available.

Taste and Quality are Excellent!
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
Thorne has a reputation for high quality products so I thought I’d try this whey protein. It tastes really good! I find it easy to digest, and it dissolves easily. I plan to make this my go-to whey protein.

Definitely sweet but good mixed
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
The vanilla would be too sweet on it's own for me but with strawberries and spinach it's perfect.

Horribly ‘weird’ sweet flavor
Flavor Name: Vanilla, Size: 30 Servings (Pack of 1)
Horrible taste - synthetic sweetness than destroys my shakes. I bought Thorne because of its high quality but this is one of their products that won’t work for me. I’m struggling through the jar because it’s too expensive to waste. Using cacao powder, cinnamon & cardamom to try to tone down the overwhelming ‘sweet.’
