Coaxial dual driver design and sound quality of Radiotehnika Cometa TB-22C
The coaxial layout minimizes interference between the tweeter and woofer. The 6mm titanium diaphragm handles high frequencies, while the 10mm graphene diaphragm covers bass and midrange. Their combined output aims for a flat frequency response and balanced tonal character across the audible spectrum, from 20 to 22,000 Hz.
The modest 16-ohm impedance combined with a 105 dB sensitivity allows these earphones to deliver strong audio levels straight from most smartphones and portable players without an external amplifier.
Controls, connectivity, and ergonomic features of Radiotehnika Cometa TB-22C
The Cometa TB-22C connects via a 3.5mm right-angle mini-jack and features a 1.2-meter cable with an inline remote and microphone for calls and music control. The fabric braided cable jacket helps reduce tangling.
Constructed from plastic and aluminum alloy, the earphone bodies have a matte finish with an ergonomic shape that fits securely without applying excessive pressure. Each earpiece weighs just 5 grams, keeping the combined weight at 16 grams. Included are silicone tips in multiple sizes for a customized fit, along with a fabric carrying case for convenience.
Radiotehnika offers a one-year warranty for the Cometa TB-22C. These headphones are available through authorized Radiotehnika dealers.
In a market dominated by global brands like Apple and Samsung, Radiotehnika’s TB-22C provides an affordable in-ear headphone option emphasizing sound detail and quality materials such as titanium and graphene drivers. This appeals to audiophiles on a budget or those seeking a unique alternative to mainstream models.
