Design and features:These headphones closed design and electronic noise canceling feature reduce both outside noise and sound leaking out into your environment. The headphones work with or without the noise canceling feature being turned on. You can use the noise-canceling feature without listening to music, and the audio cable can be detached to get it out of the way when the headphones are being used for noise reduction only. The headphones have medium sensitivity when the noise cancelation feature (either level 1 or 2) is turned on so they can provide satisfying volume levels when used with home audio equipment and all but the lowest powered portable audio devices. When powered and cycled through the noise cancelation feature to "noise cancelling off" they have medium high sensitivity; they can provide satisfying volume levels when used with home audio equipment and even lower powered portable audio devices. When the headphones are not powered (turned off), or when they are first powered on but have not been cycled to the noise canceling feature they have very low sensitivity; so while they can provide satisfying volume levels when used with home audio equipment and higher powered portable audio devices, they are not a good match for lower-powered portables. The PuroPro has a volume control plus an integrated microphone and player function controls and integrated call connect/disconnect controls. Additional features include 85dB/95dB max volume level limit control. Detachable audio cable. Earcups fold and swivel for ease of carrying and storage. It has two noise reduction levels. Has power on/off, Bluetooth pairing, and battery level voice announcements. Supports Apple Siri digital voice assistant when used with Bluetooth devices that have that feature. Bluetooth connected Apple mobile devices using iOS Version 5 and above will show the battery level. This model comes with Detachable 45-inch long standard audio cable with built in volume limiting feature, USB charging cable, carrying case.
Sound quality:We found the PuroPro delivers sound quality that falls in the very good range - it reproduces music and voice very well although it does have some noticeable sonic quirks and excellent active noise reduction. With the maximum noise cancelling mode engaged the bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep, but is prominent and boomy. The midrange (voices, guitars, horns, etc.) is even, but is somewhat grainy, and a bit hazy. The treble (cymbals, the upper range of violins, etc.) is extended but is slightly prominent and somewhat smeared (sounds that should have a delicate shimmer sound blurred). The sound also has a good sense of liveliness and is somewhat open--sound-wise it almost seems like you don't have anything plugging up your ears. It does a decent job of recovering room ambience (the sense of the acoustic space in which the audio program that's being listened to was recorded). Mixed character - Warm bass with neutral midrange and treble. The overall sound can best be summarized as bassy and somewhat grainy. When battery power is turned on while cord connected to AC powered devices this model may produce a noticeable humming and/or hissing noise regardless of whether the noise cancelling feature is turned off or on. Noise Canceling: Excellent noise reduction across the entire frequency range with the low frequencies reduced the most. A very faint hiss can be heard when there is no audio program to drown it out.
Comfort and Fit:We found that these headphones produce a sense of light to moderate pressure around the ears.
As typical of over-ear models the ear pads might feel hot and/or sticky after prolonged use.
Large
Users with larger ears might find that the over-the-ear fit of the ear pads feel cramped, or that the ear pads sit on, rather than around their ears; in that case the less-than-ideal fit around the ears might interfere with the earpad seal and reduce the noise reduction capabilities of the headphone.
Users with larger heads might find that the headband does not have enough adjustment range to allow the earcups rest properly on the ears and/or that the headband presses uncomfortably on the top of the head.
Small
Users with smaller heads may find they can't get a good earpad seal and that the bass becomes a bit subdued (earpads gap at the top), and that when they lean far forward the headphones feel unstable and shift forward, but not to the point of falling off.
Other noise
When wearing this model while walking the muffled vibrations from each foot step can be heard through the headphones.
When the audio cord is used the sound of it rubbing on clothing may be faintly heard through the headphones.
