The Sennheiser CX 2.00i is an affordable earphone with a three-button in-line remote and integrated mic. There are two versions of the CX 2.00. The first is the 2.00i, which is optimised for iOS devices. The second is the CX 2.00G, which is designed for Galaxy (Android) devices.

The product is part of the CX line, which has a range of earphones at different price-points. The Sennheiser CX 1.00 is the cheapest option in the line and has little in the way in features. The pricier Sennheiser CX 3.00 bumps up the quality and has some new design features. Both the CX 1.00 and CX 3.00 lack mic or remote. The Sennheiser CX 5.00G is made of premium components and includes a mic and remote.

Minimal accessories for Sennheiser CX 2.00i

In the box all you get is the earphones and four eartip sizes (XS, S, M, L). Don’t expect any clips or protective cases with this model. It’s worth going through the eartip sizes to pick the best one for you. If you don’t get a proper seal the bass response will be underwhelming. The earpieces are angled which helps them fit naturally within the curve of the ear. The eartips are “noise blocking” but do not provide noise cancellation. The CX 2.00i has a three-button remote which allows you to answer calls and control your music. It’s a pretty standard set-up and it does the job.

The Sennheiser CX 2.00i has a 1.2 m cable. It splits into a Y-shape, which can be shortened for comfort using the attached sliding cable tie. The remote is situated along the cable which leads to the right earpiece. The weight of the remote can pull the eartips out of your ear during vigorous movement, so the earphones are not well suited to sports applications. The cable terminates at a 3.5 mm angled jack plug. There’s a small gap to allow the jack to accommodate a phone case. The jack set-up is similar to the other products within the CX line. The earphones weigh 15g. For comparison, the Sennheiser CX 3.00 weights 12g, while the Sennheiser CX 5.00 comes in at 16g. The cable does not feature any tangle-free technology, and hence can be somewhat prone to the issue.

Balanced sound from CX 2.00i

The Sennheiser CX 2.00i earphones have a frequency response of 17Hz – 20kHz, SPL rating of 119 dB and impedance of 28 Ω. They aren’t a professional-grade product, but with that taken into account they provide fairly balanced reproduction. Sennheiser state they have:

“rich and vibrant bass-driven sound.”

The bass is satisfying but it isn’t quite as prominent as the company’s PR would suggest. If you are accustomed to listening to earphones with a big bass response you may be disappointed. Listeners who favour genres that don’t rely on pumping bass may find them more to their liking. The mids and highs are clear and present.

Understated design and build

The earphones aren’t particularly flashy and have a subtle, understated design direction. If you want a more customised look, you could consider the Sennheiser Momentum In-ear model. The CX 2.00i is available in black and white. They have a somewhat similar appearance to the Sennheiser CX 5.00. The CX 2.00s tend to sit fairly flush with the ear, although the 5.00s sit out a little further. Also, the CX 5.00 has a metal earpiece, while the CX 2.00 is made of plastic. This makes the earpieces less durable, and the remote and mic can also be prone to malfunction if they are mistreated. The lack of included protective case compounds this issue. Sennheiser offer a two-year warranty on the product. Generally the company has a good reputation for honouring warranty issues.

The Sennheiser CX 2.00i is a fairly standard entry from the company, with the most notable feature being the inline mic and remote. They offer good sound for the price, although the model does have some issues with durability. They are suited to casual music listening for those who want a balanced-sounding consumer earphone.
