I wish I bought this ANR headset sooner in my career
by Hank, B-767 captain, Delta from Johns Creek GA USA 
Pros: Excellent noise reduction. Very clear audio. Comfortable to wear.
Cons: None.
Review: I already had the Sennheiser HMEC-45-KA, but purchased the Sennheiser HMEC-25-KA because it has greater noise reduction capability. I have been a pilot at Delta for 20 years, and since I am developing tinnitus, I decided to upgrade to the HMEC-25. With my new headset, with ANR switched on, I can turn the volume knob on the radio control panel almost all the way down and still hear clearly. It really makes the cockpit much quieter. I was worried that the new headset would be bulkier than the HMEC-45, but it is not, and is very comfortable. I really enjoy this headset.

Good Long Duration Head Set
by A Customer from Salt Lake City, UT 
Pros: Light and very comfortable for long durations
Cons: No auto-off feature for ANR, and battery life is short
Review: I have been using this headset in a CRJ for 5 years now, and it's great, with the exception of no auto off feature for the ANR. I can wear this for 6+ hours a day and it's still comfortable and does not give me a headache. I recently purchased a Lightspeed Zulu thinking I would finally retire the Sennheiser, the Zulu is quieter, but it's also twice as heavy and simply not as comfortable for long durations as is this. I have since swithced back to the Sennheiser.

Great ANR headsets
by Michael Hoeck from EDFM / Mannheim 
Pros: see review
Cons: using batteries
Review: We use them in a Citation Sovereign, very good nose suppression and very clear audio quality... Light and comfortable, one can wear them for long hours without prob. (had 45 KA´s before and didn´t like them on long flights)
Only small drawback is that it uses batteries...(2x AAA) - but with rechargeable ones and a charger thats not too bad.

Disappointed
by B from Seattle 
Pros: Light weight, compact
Cons: Uncomfortable, too loud
Review: I bought the headset expecting it to be ultra-comfortable for long legs but after 30mins it was killing me. It is super light but still clamped enough to give me a hot spot behind the ear due to it being an on-the-ear headset. There is also no volume control. Chimes were extremely loud and I could not lower the volume enough for regular communications on the comm panel w/o using earplugs. The battery pack on certain versions also flops all over the place since it is on a separate, same length cord next to the mic & phone jacks.

Review: I've been using the dj-version hd 25 for a couple of years now and they are first rate. In fact, that was the main reason for me to buy the hmec 25 ka. I'm currently attending atpl-class, so I fly mainly piston driven engines for the time being. With the ANR-system they work fine in this environment, even though a bigger headset would shut off more of the ambient noise. Still, i didn't want to invest in a whole assortment of headsets so I went for the best compromise i could find. They are very comfortable, lightweight and just feel right. The boom mic is exellent and with spare batteries! You don't have to worry about noise - even in a cessna 172. Personally I don't think they're getting uncomfortable after some time, since they're smaller an lighter than most headsets on the market. I strongly recommend them.

Review on Sennheiser HMEC-25-KA
by A Customer from New York 
Pros: ANR, lightweight
Cons: earcup, price
Review: The HMEC 25-KA is a very lightweight and comfortable closed pilot's headset with active noise compensation.

These are the ideal headsets for an RJ or 737 with a loud cockpit. The ANR is not overwhelming, just right for the cockpit environment, and the quality is top grade, as with anything Made in Germany, they are built to last.

I would definitely recommend these headsets. It is a great buy.

Sennheiser Headsets are really great!
by PMC from Germantown, MD 
Pros: Active Noise Reduction capabilities
Cons: Price, need of batteries
Review: The Sennheiser HMEC-25-KA ANR are amongst the best in the market. For loud cockpits like the 737-800, it is an excellent choice, as both its Passive Noise Reduction (ear cups) and its Active Noise Reduction characteristics provide the user with an outstanding overhaul noise suppression and quietness. The Sennheisers are more expensive than other ones available in the industry, but they are reliable, comfortable and efficient. The only real downside of these headsets is the requirements for batteries, which run out pretty fast (almost every other day of use) and with the technology available nowadays the manufacturer should really consider developing a new model that would draw its power from the airplane’s electrical system.

Review: Very light and very comfortable unless you are wearing them for more than 3 or 4 hours. You see, they rest on top of your ears instead of covering them. The earphones are pushing your ears flat against your head. Keep in mind, they are pretty light, but after a few hours my ears really start to hurt. The noise canceling works great just until the batteries fail. Then you can't hear yourself think. Remember, they don't cover your ears so all the ambient noise comes through when the power fails.
