Audiophile, Premium, Best In-Class, Sennheiser

Sennheiser is a name that is synonymous with audiophile products. They have been viewed as a premium, top-tier (dare we say "The" top-tier?) brand since the beginning of time. Laboratorium Wennebostel's time that is. In 1945, Prof. Dr. Fritz Sennheiser founded Laboratorium Wennebostel's, or "Lab W" in a pleasant half-timbered house. Fritz Sennheiser was born with a gift. When he was 11 years old, he saw an early radio that inspired him to build a crystal radio. Again, he was 11 years old. There was no turning back from that day. The following year after founding "Lab W", Sennheiser produced his microphone. From that point on, it was one success story after the other. Sennheiser's technology continued to improve, and "The Bar" continued to rise. In the mid 60's, Sennheiser released the HD 414, the world's first "Open Headphones". That very day changed the future of headphones forever. That very same headphone, the HD 414, not only helped establish Sennheiser as a leading headphone manufacturer, but it sold over 10 million units. It is the best selling headphone of all time, and Sennheiser had just gotten started.


Pro Audio is an industry filled with dozens of companies and hundreds of products. It is for this reason that you will always want to go with a trusted and reliable name like Sennheiser. The HD202II semi-circumaural, closed dynamic professional stereo headphones are great for those looking for quality Pro Audio merchandise.

This gives you a full, rich and unsurpassed sound reproduction that you can count on each and every single time. Its innovative and unique removable earcup design allows for easy and convenient storage and protection when in transport. The use of an ultra-lightweight structure will provide comfort during long listening sessions, while a convenient belt clip will allow for cable length adjustment when necessary.

Headphone Design

Headphone Type

Headphone type refers to the construction of the headphones.

Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.

Around the Neck means that the headphones wrap around the neck. This is also seen in active and sports headphones.

Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.

Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.

Over the Head
Earpiece Design

This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.

In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.

Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

Specifically For
Some headphones can use an IR Transmitter in your vehicle, while some can be plugged into your media device and be used on the go or at home.

This is the lifestyle that the headphones are designed for. Each style has unique features that make it perfect for particular people.

Disc Jockeys (DJs) require a special type of headphone that can meet their professional needs. These headphones are durable, loud, and will often allow for one ear listening.

Fashion Enthusiast:

This lifestyle speaks for itself! If you love video games and want a pair of headphones that will deliver explosive sound and allow you to communicate with others, this is where you need to shop!

Music Lover:
These headphones are made to sound great. They are designed to produce rich, brilliant sounds that will play your music in a manner that the artists would appreciate. These headphones are for those that love music.

Musical Production / Recording Artists:

Headphones need to be affordable and durable to keep up with the student lifestyle. A variety of styles can be considered a pair of student headphones.

Those that often find themselves on planes or on the road a lot. These headphones are compact, lightweight, and have a portable design. Some of the headphones in this lifestyle will feature noise cancellation technology that will help shut out outside noise.


General Features

Noise Reduction technology removes unwanted noise from a signal. Background or ambient noise can be removed to produce clearer speech and enhanced hearing. Typically these Active Noise Canceling (ANC) headphones are powered and use batteries to activate the noise canceling technology. Also referred to as Noise Reduction or Noise Cancellation.
Headphone Connection
This is how the headphones connect to the audio source.

Corded means that the headphones use a cord to transfer the audio signal.

Wireless means that the audio signal is transmitted wirelessly to the headphones.

1/4" Stereo Jack Adapter
Some headphones will come with a 1/4" stereo jack adapter to connect the usual 3.5mm jack to a 1/4" stereo plug.

1/4" Stereo jack is a larger audio jack that select electronics have.

Volume Adjustment
Volume Adjustment means that the headphone (independent of the source) can adjust the playback volume. Many headphones and ear buds have in-line volume control, which allows adjusting the audible volume from a switch on the headphones cord. Other headphones have a volume knob on the headphone can.
Built-In Microphone
This means that the headphones or earbuds have a built-in microphone. This can be a microphone on the cord, built into the headphone, or even a boom microphone. These mics can be used for music devices like iPods, for Smartphones to make and receive calls, or for gaming purposes.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
18 - 18,000 Hz
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
115 dB
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
32 ohms
Primary Color
This is the main color of the item.
Secondary Color
A color that compliments the main color of the product.

Great Headphones and best price

February 23, 2014

THese headphones have great sound quality. The bass reproduction is so good it's frightening and I am used to Kicker COmp VR's and Solo Barics. THese things are dangerous. Very clear and the head band was a bit narrow for my head so I just left them stretched to the size of my head overnight a cpl times and theyr quite comfortable. My only complaint is that the wire is not very heavy duty looking in gauge but it is longer than needed which comes in handy. like 12 feet and comes with a reel to wrap it on with a pocket clip. Great sound insulation from outside noise.

HD 202 II: Clean sound and extremely durable.

January 31, 2014

I had the previous model. I think the hallmark of these phones is their durability. Bass response could be a little better, but these are very well made phones that will last as long as you want them to. This is a problem with many of the phones I've had in the past. Shorts in the wire, plastic breaking, etc. Never happens with these HD 202 IIs. That is very important to me. My one con, would be adjusted at their widest point, they are still a bit too tight on my head. Something I can live with, but I wish there was a setting a bit looser.

You get what you pay for

February 7, 2014

I'll keep this short and simple. These headphones are not their best model and are out-dated however I thought I'd give them a try since they were very cheap. They sound good but not great. I get better sound out of my little iPhone 5 ear buds however if the kids are making a lot of noise, it is nice to have a full over the ear cover. The HD 202 also doesn't fold flat like the new ones so if you travel, they take up a lot of thickness in your laptop bag. They have a really long cord so if you want to plug into something and sit across the room, that may come in handy. For me, I had to tie the 15 ft cord up with a rubber band so it gets in the way. I wish I will probably buy a more expensive, more up to date technology next time that sounds more crisp.
