Sound performance in headphones is measured by the range of treble, bass and mid sounds the headset delivers. This range is commonly known as frequency response. The audible frequency range humans naturally hear is 20 to 20,000Hz, but the Sennheiser HD 449's frequency response is 16-24kHZ, giving you a little extra clarity to add to your music experience. The HD 449s are able to have loud output thanks to a sensitivity rating of 114 decibels, which is high among comparable headsets.

The HD 449 uses a 32-ohm, low-impedance transducer to deliver high quality sound without requiring an additional amplifier. This makes the HD 449 great to use with most portable devices such as tablets, MP3 players, smartphones and laptops. While this over ear headphone set is geared more towards the portable market, the HD 449 is still strong enough to use with higher impedance audio equipment like DJ mixers. While the HD 449 does get a boost from this increased range, it does not necessarily mean that the sound quality is better. We noticed that while the Sennheiser HD 449s deliver accurate, high quality audio, they lack in the bass department. If you listen primarily to bass-heavy music genres like R&B, Techno, Rap or Dance, you may want to use the HD 449s with an amplifier.


The Sennheiser HD 449 sports a 4-foot long cable with a 1/8-inch gold plated connector. One feature we are happy to see is that the cable only connects to the left earphone, instead of using a standard Y connection. This makes it easier for you to keep your cable from tangling or getting in the way. The best feature of the Sennheiser HD 449 is its weight. These headphones only weigh 6.9 ounces and do not grip your head with vise-like hold, so you will be able to wear this headset comfortably for hours.

The HD 449 is a closed-ear headset, constructed of plastic with no visible metal. There is padding on the headband, and the earpads are soft leatherette cushions. While the closed-ear design helps block mild ambient noise sounds, we are disappointed that there is no additional noise-canceling feature. The earpads are also somewhat narrow, so if you have larger ears you may find it a little uncomfortable.

The HD 449 headset does not fold, making it a little inconvenient to store or transport. We also would like to see an option to have a detachable cable.


Sennheiser includes a 5-foot extension cord, perfect for lounging or moving around without your headphone jack popping out. The included carrying pouch is large, but it does not offer much in the way of protection , so you will need to be careful when storing your HD 449s in bags or suitcases. A 1/8- to 1/4-inch adapter is included so you can connect to DJ or stereo jacks. We are impressed that Sennheiser includes the extension cable and the adapter, as most companies do not include much beyond a storage bag. Also, the soft leatherette earpad cushions are replaceable and not too expensive.



Sennheiser offers comprehensive support for all its products. You can access product FAQs or online manuals to find answers to your operating questions or submit a technical support ticket through email. If you prefer to talk to someone directly, Sennheiser offers a toll-free telephone number. The Sennheiser HD 449 headphones have a two-year limited warranty that covers manufacturing defects, but not user-inflicted damage. We are impressed with the thoroughness of Sennheiser's customer assistance, and it is good to see a company stand behind its products.



The Sennheiser HD 449 stereo headphones are comfortable and great sounding. Although there is no noise cancelling beyond the closed earpad design covering your ears, their lightweight design makes them comfortable to use for extended listening sessions. Additionally, their accurate sound reproduction make these headphones a great choice for any music lover or audiophile.
