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.

These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.

Rusty LOVES them.
Size: Large
Our dog loves these balls! I like that they squeak and the texture prevents them from getting slimy from his spit. They last more than smooth balls. You do need to make sure you get the right size for your dogs mouth.

Squeaker Does NOT Break in a Day
Size: Large
My mid-size, 40lb heeler mix loves these chew balls. They are easily his favorite toys to fetch, chase and chew on. We’ve had the chew balls for several months, and, unfortunately the squeaker does not break in a day. They are still going strong. Extremely durable and great value for the money.
