Sennheiser PXC 550-ii
Open-back headphone designs are often higher-performance but have poor noise isolation and leak sound. Closed-back designs provide better noise isolation and leak less sound.
Over-ear headphones sit over your ear and surround your ear with a ring of padding. On-ear headphones are padded but rest on top of your ear. In-ear monitors are worn inside your ear canal.
Speakers and headphones use a device called a 'driver' to create sound. Different types of drivers have different strengths and weaknesses, but can all produce great sound. Common varieties include dynamic, planar magnetic, and electrostatic.
Connectivity refers to the method in which the headphones connect to the audio source. Headphones can be either wired or wireless.
Designed for all-day use, the PXC 550-II Wireless Active Noise-Canceling Over-Ear Headphones from Sennheiser provide you with up to 30 hours of battery life, padded earcups and headband, and easy access to your smartphone. The PXC 550-II headphones have an integrated voice assistant button that connects you to your phone's digital assistant, such as Google Assistant, Siri, or Alexa. Once connected, a beamforming 3-microphone array helps to focus onto your voice for clearer commands, questions, and hands-free conversations.
Featuring active noise-canceling technology, the PXC 550-II headphones will filter out ambient noises and sounds that can distract you from your favorite music or an important conversation. The degree of noise cancellation can be customized via the Sennheiser Smart Control app for iOS and Android devices, so you can tone it down or activate Transparent Hearing to get back in touch with your surroundings when needed. The Smart Control app also features a built-in equalizer to optimize sound quality for your audio content.
Support for Bluetooth 5.0, aptX, and aptX Low Latency
Headphone sensitivity measures how loud a pair of headphones will be at a given signal strength. Headphones with higher sensitivity ratings will produce louder sounds than headphones with lower sensitivity ratings. It is measured in dB SPL (decibels of sound pressure level) per unit of power (typically 1 milliWatt) or sometimes unit of voltage (typically 1 Volt) from the source at a frequency of 1 kHz.
|110 dbSPL (passive : 1 kHz/1V RMS)|
Total Harmonic Distortion (THD)
When driving headphones at high volumes, it is possible for the diaphragm (the ‘speaker’ inside the headphones) to be unable to move fast enough. This leads to distortion, manifesting itself as crackling, popping or the alteration of musical notes. Most headphones will fall below 1% THD.
|<0,5% @ 100 dBSPL / 1kHz|
Headphone frequency response refers to the frequency-specific sensitivity of the output. Frequency responses show the range that headphones are capable of reproducing—a graph shows which frequencies are accentuated over others. The ideal range covers the audible sound range of 20 Hz – 20 kHz.
|17 – 23,000 Hz (-10db)|
