Design: A sporty, streamlined design

You don't need to take a bulky pair of headphones with you when you go for a run, or to the gym. Sennheiser's CX Sport earbuds are extremely lightweight. These were easy to carry around the neck, or in my pocket in the handy nylon pouch. The IPX4 water resistance rating makes them sweat-proof.

CX Sport has a sporty look with a black overall build and lime green accents at the remote control panel. The wing tips accent the rubber adapters and in-ear rubber adapters. Three buttons are included on the remote control panel that make it easy to use and responsive. You'll also notice the larger, rectangular-shaped battery package located opposite. Although it does not add weight to your earbuds, it can make them feel bulky. The adjustable neckband was also a barrier to better fitting.

Comfort: Relatively secure—with some experimentation

It would be expected that a set of headphones suitable for workouts should fit snugly, but these usually do. The earbuds fit very awkwardly, so the medium ear tips are attached to the box. Although the medium-sized ear adapters worked well, I was not satisfied with how the ear fins fit in my ears. The small fins were too big for me. I found that no earbuds were necessary. Although the fit was not as tight as I wanted, the earbuds did not fall out of my ears while I ran or cycled. While I doubt I will get the same results with longer runs or more unpredictable movements, short sprints worked just fine.

You could also try to get an extra hour out of your battery by using a 10 minute charge.

Although I had trouble with three sets of extra-small to big ear fins and four sizes of adapters, the CX Sport earbuds fit perfectly. You can adjust the neck cable to adjust the length. The shirt clip is a great way to add extra security and stay-fit. It can also be used as an anchor point for any movement.

The length of the cord was another barrier that prevented users from engaging in an easy workout. The length of the cord seemed to be either too short or too long. The remote control panel was difficult to reach when I tried to fit it with the cinching device. To use the remote controls, I had to be careful, particularly when running. Although the fit was good enough to not worry about the earbud falling out, I had to adjust it after I made contact with the remote.

Sound Quality : Relatively low-key

Many users reported a positive bass experience using these earbuds. However, my experience was not satisfactory. Sennheiser emphasizes that the bass sounds were the warmer and most resonated tones. The flat quality of the mid-frequency audio was what struck me most. Sometimes vocals were a bit harsh and tinny. Songs with high treble and vocals sometimes seemed too sharp or even harsh. Classical music was balanced, while contemporary pop songs tend to be shrill.

Although the CX Sport supports Qualcomm aptX, Qualcomm aptX high latency technology and Qualcomm aptX, these earbuds were used to stream music from iOS devices that use the AAC audiocodec. To provide an accurate, delay-free and better audio experience on mobile and desktop devices as well as gaming platforms, the aptX technology is being used more frequently. These audio codescs are designed to replicate the experience of a wired connection.

You won't be able to find noise cancellation on the CX Sport regardless of what device you are using, however the microphone quality is adequate for answering calls and answering questions.

Battery life: Good but not exceptional

Sennheiser claims that the CX Sport's battery life is six hours. The battery life of the CX Sport is only six hours, which means that you will need to charge them frequently if they are to be used for everyday workouts or casual usage. They charge quickly using the micro USB charging cable. You can charge the battery for 10 minutes to get an hour of life if you are in dire need. But it's more worthwhile to wait for just a little over an hour, which is enough time to bring the battery to 100 percent—and faster than the manufacturer claim of 1.25 hours.

Range and Capability: Continually short

According to the manufacturer, these earbuds can support a distance of 32 feet. The CX Sport couldn't reach that limit. It was so bad that I couldn't move more than 10 feet from the stream source, before it would drop completely.

These earbuds are popular for their bass, but I found them lacking in my experience.

Prices: High-priced and not a great buy-in

Sennheiser's CX Sport headphones retail at $130 MSRP. Although the cost is not prohibitive, it's still a high price. It has a low water resistance rating and is not very good in terms of sound quality. If you don't have any issues with your ear fins it is possible to get a better fit. These earbuds are a great addition for the gym. There are cheaper options that offer a little more, or even a lot.

Sennheiser CX Sport vs. Status BT Structure

You can get 12 hours music, a better IPX-5 rating and dual-driver technology (see Amazon) for $51 less. Two drivers are supposed to be more accurate at handling high and mid frequencies, while one driver focuses on the bottom end.

The BT Structure may be more suitable depending on which type of headphone you prefer, e.g. earphones or earbuds. The BT Structure wireless earbuds have four sizes inner-ear tips, and an over-the ear hook fitting. Although some people don't like this type of headphone design it can provide more secure and simple fit than the CX Sport's ear fin and adapter configuration.

Status earbuds are compatible with many devices because they support Bluetooth 5.0 and aptX. The earbuds that are comparable to the Status are slightly heavier, at 0.88 ounces. However, they come with identical accessories, such as a carrying case, clip, and organizer, making it easy for you to achieve fit and portability.

Final Verdict

If you're willing to pay a bit more, a decent pair of earphones for your workout.

Sennheiser CX Sport wireless headphones offer a mix of attractive features. They include sporty styling and tools to achieve a better fit. The charging time is the best feature, but some other features are a little lacking considering the price and audio quality. These could be your best choice for exercising if you don't mind paying a bit more and get the perfect fit.
