User reviews
Design
Fit
In-ear
The fit of the headphones.
weight
Unknown. Help us by suggesting a value.
We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
has a detachable cable
✖Etymotic ER 4PT
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
Ingress Protection (IP) rating
Unknown. Help us by suggesting a value.
The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid. E.g. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.
can be folded
✖Etymotic ER 4PT
Foldable devices are easier to transport and take up less storage space.
has a tangle free cable
✖Etymotic ER 4PT
The cable is designed to minimize tangling.
travel bag is included
✔Etymotic ER 4PT
The device comes with its own special case or pouch, which is useful for safe transportation.
has an open-back design
✖Etymotic ER 4PT
The device is designed in a way that allows sound to go out through the back of the ear cups, which usually have vents or perforations. This design provides very natural and accurate sound.
is dustproof and water-resistant
✖Etymotic ER 4PT
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.
Sound quality
has active noise cancellation (ANC)
✖Etymotic ER 4PT
This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.
lowest frequency
20Hz
The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
highest frequency
16000Hz
The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
driver unit size
Unknown. Help us by suggesting a value.
The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
impedance
27 Ohms
Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.
sound pressure level
102dB/mW
Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
has a neodymium magnet
✖Etymotic ER 4PT
Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.
has passive noise reduction
✔Etymotic ER 4PT
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
Power
Battery life
Unknown. Help us by suggesting a value.
The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.
charge time
Unknown. Help us by suggesting a value.
The time it takes to fully charge the battery.
Has USB Type-C
✖Etymotic ER 4PT
The USB Type-C features reversible plug orientation and cable direction.
has a battery level indicator
✖Etymotic ER 4PT
An indicator shows you when the device has low battery.
has wireless charging
✖Etymotic ER 4PT
It supports a wireless charging standard such as Qi. To charge the device, you simply put it down on a compatible charging pad.
battery power
Unknown. Help us by suggesting a value.
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
has a rechargeable battery
✖Etymotic ER 4PT
The battery can be recharged and used over again.
has a removable battery
✖Etymotic ER 4PT
The battery is removable and can be replaced by the user if broken.
Connectivity
Connectivity
Wired
The connectivity type of the headphones.
Bluetooth version
Unknown. Help us by suggesting a value.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
has aptX Adaptive
✖Etymotic ER 4PT
aptx Adaptive is an audio codec for Bluetooth devices that is developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.
has aptX
✖Etymotic ER 4PT
aptX is a codec used for transmitting audio wirelessly with Bluetooth. It is developed by Qualcomm, and supports 16-bit audio at a bit rate of 384kbps.
has LDAC
✖Etymotic ER 4PT
LDAC is a codec developed by Sony for Bluetooth audio. It is capable of a very high bitrate of 990kbps, which provides high resolution audio. It can also automatically adjust to a lower bitrate of 330kbps or 660kbps to increase stability.
has aptX Low Latency
✖Etymotic ER 4PT
aptX Low Latency is a codec developed by Qualcomm. It uses Bluetooth 5.0 technology to provide low latency audio (around 40ms), which is useful when you want to avoid audio lag (e.g. when playing games).
has aptX HD
✖Etymotic ER 4PT
aptX HD is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 24-bit audio (at a bit rate of 576kbps).
has aptX Lossless
✖Etymotic ER 4PT
aptX Lossless is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 16-bit/44.1kHz audio (at a maximum bit rate of 1200kbps). This codec provides CD-quality audio without any loss of data.
has AAC
✖Etymotic ER 4PT
AAC is a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.
Features
has a noise-canceling microphone
✖Etymotic ER 4PT
These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.
has ambient sound mode
✖Etymotic ER 4PT
Ambient sound mode uses microphones to pass through ambient noises so that they can still be heard. It’s useful when you want to listen to music but also be aware of what’s happening around you, for example when you’re jogging but still want to be able to hear traffic.
