Sennheiser CX 175 Earbud Headphones

The Sennheiser CX 175 are wired earbud headphones with a 3.5mm connector and a 1.2m cable. They use dynamic speaker systems and include ear adaptor sets for a secure ear canal fit. The design targets listeners who want straightforward, portable audio from devices with a standard headphone jack.

Upgrade from basic earbuds

These replace bundled earbuds that often lack noise attenuation or a tailored fit. The supplied adaptors improve isolation and comfort, while the dynamic drivers deliver a frequency response of 17Hz-23KHz and THD below 1%. The jump is worth it when you need better seal and clearer sound without batteries or pairing.

Capacity and headroom

With 16 ohm impedance and 121dB sensitivity, the CX 175 reaches loud volumes from smartphones, tablets or laptops without an amplifier. The 1.2m cable suits desktop or pocket use. They run out of headroom in noisy environments where passive attenuation cannot block low-frequency drone, and they offer no inline remote or microphone for calls.

Questions about this item

What size ear tips are included with the CX 175 for a secure fit?

The package supplies multiple ear adaptor sets so you can choose the size that seals your ear canal and blocks outside noise.

How do I plug the 3.5 mm connector in without damaging the jack?

Align the straight 3.5 mm plug with the socket and push straight in until it clicks; forcing it at an angle bends the contact pins.

When should I replace the ear adaptors on these earbuds?

Swap them when the silicone loses elasticity, tears, or no longer stays seated in your ear, which degrades the 17 Hz – 23 KHz seal.
