Design
Fit
In-ear
The fit of the headphones.
weight
117g
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
Foldable devices are easier to transport and take up less storage space.
has a tangle free cable
✖HiFiMAN RE400
The cable is designed to minimize tangling.
travel bag is included
✔HiFiMAN RE400
The device comes with its own special case or pouch, which is useful for safe transportation.
has an open-back design
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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)
✖HiFiMAN RE400
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
15Hz
The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
highest frequency
22000Hz
The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
driver unit size
8.5mm
The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
impedance
32 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
✔HiFiMAN RE400
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
✔HiFiMAN RE400
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
✖HiFiMAN RE400
The USB Type-C features reversible plug orientation and cable direction.
has a battery level indicator
✖HiFiMAN RE400
An indicator shows you when the device has low battery.
has wireless charging
✖HiFiMAN RE400
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
✖HiFiMAN RE400
The battery can be recharged and used over again.
has a removable battery
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
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
✖HiFiMAN RE400
These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.
has ambient sound mode
✖HiFiMAN RE400
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.
has in/on-ear detection
✖HiFiMAN RE400
Sensors can detect when they are removed from your ears so that the music is paused, saving battery life.
number of microphones
Unknown. Help us by suggesting a value.
More microphones result in better sound quality and enable the device to filter out background noise.
has a mute function
✖HiFiMAN RE400
The device has an option to mute/unmute a conversation directly from the device.
multipoint count
Unknown. Help us by suggesting a value.
Multipoint allows you to link to more Bluetooth devices and switch between them. For example you can easily switch calls from one device to another without having to manually disconnect and reconnect.
control panel placed on a device
✖HiFiMAN RE400
There is a control panel on the device body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.
