The Sennheiser CXC-700 are great-sounding in-ear headphones that have decent, slightly bass-heavy audio reproduction with most tracks. Unfortunately, they perform poorly at isolating the listener, the subpar noise cancellation being really disappointing. The in-ear fit may also be uncomfortable for some.
The CXC-700 are a decent-looking pair of in-ear headphones. The control module feels rugged and durable and the headphones are esthetically pleasing. However, the omission of the play/stop button is a let-down and the cable could have been a little more rubberized. The in-ear fit is also, a little unstable and is easily dislodged by a gentle tug on the cable.
The in-ear design may not be for everyone but once you have a good fit they can be quite comfortable. Unfortunately they are not very stable within the ear and a slight tug on the cable will ruin the comfortable fit. This issue happens with a lot of in-ear designs, and makes the comfort for the CXC-700 average.
Button layout and control options are average at best, due to the omission of a play/stop button. The controls offered by the CXC-700s are volume and noise cancelling slider switches, a mode button to alternate between noise cancelling modes and a talk-through button that mutes the audio.
The CXC-700 are compact and portable headphones. They will comfortably fit into your pockets, purse or bag. The control module makes them a little larger than basic in-ear headphones but doesn't add that much bulk to the overall portability of the headphones.
Comes with a decently rugged soft case that will protect the headphones from scratches and minor falls. It's also not too big and will fit in a pocket. Unfortunately, it will not shield the headphones from water damage or high physical stress like accidently walking on the headphones.
The Sennheiser CXC-700 are below-average stable for in-ear headphones. The design of the in-ear fit does not enter the ear canal far enough, which makes them relatively easy to dislodge. They stay in place during casual listening sessions but are not stable enough to be used at the gym or while doing high-intensity physical activities. They also don't offer any special stability tips to prevent the earbuds from falling out which is slightly disappointing.
The Sennheiser CXC-700 is a decent sounding pair of closed-back in-ear headphones. They have a well-balanced and extended Bass, a very good Mid Range and an excellent Treble. They also perform consistently across multiple users, and have low distortion. However, the Bass is very slightly muddy, their Mid Range is a bit recessed, and like most other in-ears, they have a poor Soundstage.
The CXC-700 disappoint with their noise isolation performance. They do not deliver solid active noise cancellation and fail at isolating the listener in noisy environments. They shouldn't be your first choice for international travel but do however offer a tight seal that does not leak much sound if the in-ear fit is right.
Poor noise isolation. With noise-cancelling set to Off, isolation starts at around 500Hz and reaches -30dB at 4KHz. Active noise cancellation seems to only marginally improve the mid-range isolation, at the expense of treble isolation.
Very good leakage results, as is typical of in-ear headphones. The leakage's profile is quite narrow-band too: 3KHz-6KHz.
The Panasonic CXC-700 are not the most versatile headphones. They only have noise canceling as an active feature. Hence no wireless or app score. On the upside, they have a somewhat decent battery life that will last about 17.2 hours. However, that slightly lower than typical active in-ears that use AAA cells.
The CXC 700 have an average battery life. They will continuously play audio for about 17.2 hours at average volume levels but have no power saving features and since they use AAA batteries that means, you will have to have a couple of cells spare if you plan on using these headphones on a long road trip. On the upside, they can be used passively when the noise canceling is switched off or battery is dead.
No compatible app.
