The newly developed HD 300 PROtect delivers huge depth of detail, even in the loudest of environments. Whether you are editing, playing or composing; whether you’re behind a drum kit or a mixing desk; the HD 300 PROtect provides incredible wearing comfort and the incredibly detailed sound required to make good decisions.

The HD 300 PROtect adds Sennheiser’s patented ActiveGard™ technology, for advanced protection from peak levels above 110 dB. With ActiveGard™, disruptive or harmful peaks are brought down to a safe level, preserving clarity and control at all times. The HD 300 PROtect satisfies European EC noise directives on industrial safety and noise control while safeguarding hearing for all production staff, even in the event of big surprises.

Viscoelastic earpads and specially sealed acoustic elements provide efficient shielding against external noise. A high level of wearing comfort is ensured by optimum pressure distribution and a recess for the fontanelle. Structure borne noise is filtered out through a coiled cable directly by the earpiece.

ActiveGard™

  • Patented sound compression system consisting of a sophisticated electrical circuit incorporated into analogue headsets.
  • Utilizes a compression technology to remove the energy from an excessive incoming signal transmitted through the communication system, leaving the signal free of distortion.
  • Can be compared to an automatic and fast-working “intelligent” volume control. If an incoming signal rises to a level that is harmful to your hearing, it is instantly “turned down” to a lower, more comfortable level.
  • When the incoming signal returns to safe levels, ActiveGard™ reverts to its stand-by surveillance mode and volume is restored to its original level.

Nameplates for Customization

  • The HD 300 PRO Series headphones can be customized with a company logo or user name.
  • Minimum order quantity for customization is 10 pcs; contact us for more details.

A bit too firm but great otherwise
Color: Cool Grey, Size: 24x24x12 inch
I got this wedge pillow primarily to have something to lean my head against (I like to lay on my side when reading or looking at my phone at night sometimes), or to sit upright when reading in bed. It's very comfortable doing both now. It does a really good job at being a nice support for the back of my bed. Only negative is I feel it's too firm. I wouldn't use it as a primary pillow, but it's definitely good for back support at least. While I won't mark it down for this, I do find it very large. If you have anything smaller then a queen it may take up more of your bed then you'd like. Definitely recommend. Hopefully will last quite a long while as well.

So helpful after surgery.
Color: Solid Warm Gray, Size: 24x24x12 inch
Perfect support while recording from abdominal surgery. This pillow maintains its shape and is not overly soft. I used it vertically as a prop for watching television and then used it horizontally to prop myself up to sleep, once I returned to sleeping in bed. I used this daily for 6 weeks or so following surgery. The cover can be removed and machine washed. The non-slip nubbies are helpful. This pilllow is high quality and really helped to minimize pain and improve my sleep after surgery.

Nice wedge pillow but not enough...
Color: Cool Grey, Size: 24x24x12 inch
It came compacted and when I opened it expanded almost immediately, maybe took like 20 minutes to fully decompress. Its soft and comfortable and the cover is really nice. But it does have a strong chemical smell, which is normal for this kind of brand new memory foam, I just put it on a table with a window open near it and after maybe 24 hours the smell was almost completely gone. The problem is that I bought this to have a elevated position when sleeping but the 30° are just not enough for me. I wish it was at least 45° but I could not find any pillow with that amount of degree... it's either 30° or like 75° in the other position. At the base of the pillow there is a little ridge that is comfortable for the lower back but makes me slide down in the middle of the night so I end up almost laying flat with my neck on the base ridge. With my slim build my lumbar area gets some nice support but makes my head almost have a "fall backwards" sensation, I like having my neck have a "push-forward" position with my pillow, but when adding another pillow to try and get to a comfortable position it only makes me slide down even more... :/

Very firm and durable
Color: Cool Grey, Size: 24x24x12 inch
worked great for husbands surgery recovery. Very affordable, firmness was great, looked nice on the bed and also used it for the grandkids when they were watching a movie. Moved around with ease. Didn't use it to sleep with all night though. He could only make it half the night but that wasn't the pillows fault. It was the cast on his arm. Definitely did its purpose after surgery and the need to sit up in bed more. highly recommend

Sasstie Wedge Pillow
Color: Cool Grey, Size: 24x24x12 inch
Perfect. I used it when I was recovering from hip surgery. Relieved a lot of pain in my hip and knee at a time when I needed relief.
