CRYSTAL AUDIO manufactures affordable High-End audio equipment, including Bluetooth speakers, headphones, and soundbars, known for their wireless connectivity and dipole speaker heritage.
KRISTAL AUDIO, also known as Tsakiris Vasileios or Crystal Acoustics, has been engineering affordable High-End audio products since the release of its first Dipole Speakers in 1999. The brand specializes in consumer electronics designed to deliver premium sound quality without the premium price tag. Their product lineup includes wireless Bluetooth headphones, portable speakers, soundbars, and home theater accessories.
Headquartered in Europe, CRYSTAL AUDIO products are distributed internationally, though specific warranty terms often apply to their primary markets, such as Greece. The company also develops ODM products for major international retailers. Known for robust bass drivers and reliable wireless connectivity (Bluetooth 5.0 in recent models), their devices cater to audiophiles seeking value and performance.
