Bottom Line

The Sennheiser CX 1.00 earphones are an entry-level model with no bells or whistles to speak off. The response is clear but is somewhat lacking in the bass department.

The Sennheiser CX 1.00 earphones are a budget product from the German company. They are the cheapest model in the CX line, which also features the Sennheiser CX 2.00i, Sennheiser CX 3.00 and Sennheiser CX 5.00G models. The CX 1.00 earphones are simple to use and have no frills or extra features. They are available in black and white.

Light and comfortable build

The CX 1.00s are light (10g) and comfortable. They have a plastic construction and once fitted in your ear it’s easy to forget they are there. Naturally the plastic components are not going to be very durable. Sennheiser do offer a two-year warranty on the product. The CX 3.00 earphones have metal earpiece so if durability is a particular concern you may consider that model. In appearance and build the CX 1.00s are closer to the old Sennheiser CX 300II model than the other current designs offered by the company. Both have a traditional appearance and low-profile, non-angled earpieces.

The earphones have a standard 1.2m rubber cable, which is well-suited to their intended portable use. The cable can be prone to a degree of movement noise. It terminates in a 3.5mm angled jack. The jack has a slim gap between the angled jack and the device, but it’s enough to accommodate a phone case. The jack design is very similar to the design used on the more expensive products in the CX line. There is no remote, mic or any additional features included along the cable-length.

Minimal features for Sennheiser CX 1.00

The Sennheiser CX 1.00 earphones ship with the bare minimum of accessories. All you get in the box is the earphones themselves and four ear adaptor sizes (XS, S, M, L). The ear adaptor options are pretty standard but they do help ensure you can tailor the fit to your ears. A good seal is important to getting the best sound out of the product. Unlike the more expensive options in the CX line, the CX 1.00s do not have any noise-cancellation. Sennheiser state that the ear adaptors are “noise blocking” but don’t expect them to work wonders. If ambient noise is a concern these are not a good choice.

Clear sound but bass is lacking

For the price, the CX 1.00s offer fairly balanced reproduction. Obviously for such a budget pair of earphones, you aren’t going to get pro-level sound quality. The frequency response is 17Hz – 20kHz. They have pleasant highs and clear mids. Sennheiser claim the earphones have “deep and punchy bass” but that should be taken with a grain of salt. The bass is not very prominent. That said, there are plenty of models out there with hyped bass so perhaps this aspect of the design will appeal to some. If you want a heavier bass response the Sennheiser CX 3.00 model could be more up your alley.

The Sennheiser CX 1.00 earphones are an entry-level, no-nonsense model with no bells or whistles to speak off. The design is very traditional. This means that the earphones don’t have the advantages of more recent design advances. They have a pleasant, balanced sound, but the bass response is lacking. The CX 1.00s have a plastic construction so will not be the most durable product, but for the price you could probably stand to replace them every now and then. You also have the benefit of a two-year warranty. The model doesn’t really stand out in any way but if you just want a stock standard pair of affordable headphones, the CX 1.00s will do the job.

These are basically quite good. Overall, very nicely balanced sound (I'd prefer a little more rumble in the low bass, however) with good detail and presence.


These ear buds are fantastic. Extremely comfortable in your ear, can't even feel them.


Good headphone for this price. Recommended for anyone who wants to upgrade from headphones that come with devices.


The bass in my opinion lacks slightly, but then again I am a pretty big bass head and the bass is more noticeable at higher volume levels.
