Lavender Sounds is a Thai DIYer. I think he's well respected in Thailand.

Happy Friday!
For many, this is probably one of the happiest days of the week—a time to take a break after a long and tiring week.
Today marks a great occasion to launch pre-orders for the Lavender Black Luthenium earbuds.
Specifications:
Driver: 14.5mm Dual Magnet with Custom Diaphragm (CNTS), 32 Ohm. This driver is specially ordered for this project and is not available on the market. If you want one, you’ll have to negotiate directly with the factory.
Body: Brass with a Black Luthenium coating, featuring a 5-micron gold-plated logo.
Connector: MMCX type, with single-core and stranded silver cables for both the hot and cold sides.
Sound Signature:
The sound combines monitor-like characteristics with excellent detail and focus in the mid and high frequencies. Its true standout feature lies in the bass:
Mid-bass impact: Fast and precise.
Deep bass: Strong, full-bodied, and rich, with quick decay—no lingering or muddy tones.
This is the hallmark of the Lavender sound signature, refined over years of development.
Why Dual Magnet?
The high-power dual magnet system delivers immense force, ensuring precise control over the diaphragm’s movements. This minimizes unnecessary vibration and maximizes performance. In automotive terms, it’s like having a sports car suspension—powerful and stable.
Why Isn’t This Driver Common?
This driver is expensive and represents the pinnacle of earbud technology today. Custom-made units like this are even pricier and unavailable on the general market. Additionally, its thicker-than-average size means it cannot fit into existing plastic housings. A custom body must be made specifically to accommodate it, which adds to the complexity and cost.
This is why it’s rare to see products utilizing this driver, but I couldn’t resist the challenge. The result is a truly one-of-a-kind earbud designed to push the limits of performance.
Who Is This For?
While the specs and descriptions might sound impressive, the ultimate value depends on the craftsmanship and how well its potential is realized. This earbud is not meant for casual, mainstream listeners looking for smooth, warm, easy-listening sound. Instead, it’s designed for those seeking something new and extraordinary—an experience that pairs perfectly with high-quality music players and high-resolution files to showcase their full potential.
Pre-Order Details:
Price: 8,900 THB. Full payment is required upon completion—no deposit necessary.
Production time: Approximately 2–3 weeks.
Availability: Limited, as the drivers are custom-ordered. This project was originally for personal use, but due to the factory's minimum order requirements, I had to purchase a large lot and am offering a portion for sale.
Notes:
Please read all the details carefully before placing an order to avoid misunderstandings.
For those interested, feel free to message me to reserve your unit. Thank you so much for reading—if you made it to the end, that is.
