Our Thoughts RADAR AI

At €5, this is a bargain against the CX 300 II’s usual used asking prices, which cluster around €9–€17 and can still sit around €35 new or near-new depending on stock. It’s well below the common used market, so this reads as a genuine buy rather than a maybe.

That makes sense for a small, well-liked Sennheiser in-ear: punchy bass, easy comfort, and decent isolation are the big draws, with a lively presentation that suits casual listening and commuting. At this price, the main buyer check is simple: confirm the cable, plug, and left/right balance are intact, and that the tips are included or at least usable; if those are fine, it’s an easy yes.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Sennheiser

Founded in June 1945 by Dr. Fritz Sennheiser in a farmhouse near Hanover, Germany, Sennheiser began as Laboratorium Wennebostel, producing voltmeters and early microphones amid post-World War II reconstruction. Seven engineers from the University of Hannover joined the founder, quickly pivoting to broadcast microphones like the DM 2 in 1946 and the groundbreaking MD 82 shotgun mic in 1956. Renamed Sennheiser electronic in 1958, the family-owned company passed to second- and third-generation leadership, maintaining its innovative spirit over eight decades.

Sennheiser excels in professional and consumer audio, renowned for microphones, wireless systems, and headphones that set industry standards. Pioneers of the first open-back headphones (HD 414 in 1968) and enduring studio icons like the MD 421 and MD 441, they also produce high-end headphones, earbuds, soundbars, and conferencing solutions. While strong in pro audio like mixers and geophysical gear, their consumer focus centers on headphones and wireless tech rather than amplifiers, speakers, turntables, DACs, or cables.

Sennheiser commands a premium position in the hi-fi market, blending mid-tier accessibility with high-end excellence for discerning buyers and professionals. Trusted for reliability and sonic precision, it appeals to audiophiles seeking reference-grade headphones without boutique obscurity, backed by a heritage of technological firsts that sustains its global leadership.
