The stereo Bluetooth technology provides the hands-free experience along with quality hi-fi sound, and the wired connection is great for conserving the battery when wireless is not needed.

Right out of the box you will enjoy the appearance of the headphones themselves. They have a very sleek and attractive design that is easy on the eyes.

    Wireless bluetooth headphones

    In the electronic age that we live in today, headphones are a must for most people.  Whether you use them to play a game on the computer, to listen to music on your mp3 player, or to talk on your cell phone, there are a plethora of uses for headphones.  The Sennheiser MM 450 headphones can address all of these needs by purchasing this one product.  And what's even better: they are wireless!

    When you get your box in the mail you will see that the headphones are crafted well and as you try them on you will find that they are comfortable to wear.  They have an over the ear design that does not irritate the insides of your ears like ear buds or other options might.  The Sennheiser MM 450 comes with the following included in the box: the headphones themselves, a USB cable that can be used when using them on the computer, an audio cable with an in-flight adapter, a wall charger, and a carrying case.  Some that have purchased these headphones have complained that the carrying case that comes with the headphones is not up to the standard of the headphones themselves.  It is a soft nylon bag that can fit only the headphones and possibly the audio cable, but nothing else.  However, there are places that you can purchase a hard case to use with these headphones and have them more protected as you use them.

    The pending question that most buyers have is does the product deliver on the noise canceling aspect when they are paying such a high ticket price?  For most users, that answer is a big yes.  With NoiseGard 2.0 technology, the Sennheiser MM 450 cancels noise up to 90 percent!  In addition, the headphones have the TalkThrough technology, which allows users to press one button and use the built in microphone while still using the headphones.  And you can do all of this with the convenience of Bluetooth 2.1.  Use your headphones with the noise cancellation feature for up to 8 hours, or up to 10 hours if you are not using the noise cancellation feature.  If you are not in need of the Bluetooth feature, the headphones also come with the cable.  The charging time for the battery is approximately three hours.  So if you are looking for a high end pair of headphones that offers you a noise free conversation or a great game with friends while talking on a chat server, the Sennheiser MM 450 headphones deliver.  The price tag may take you aback at first, but if you look at the reviews you will see that people who have purchased this product as opposed to others do not regret doing so.  They are well worth the high price!

    Just like their predecessor, the Sennheiser MM 450 headphones, the Sennheiser name has once again come through with a high quality product.  While making changes to improve upon complaints made about the previous model of these headphones, Sennheiser has given consumers a product that they will not be disappointed with.  While the price tag is still expensive, you are paying for the quality and the reliability of the Sennheiser brand, and you will get headphones that deliver!

    Sennheiser MM 550 Headphones

    Newly upgraded wireless bluetooth headphones

    The Sennheiser brand is well known for delivering high quality products, and the MM 550 headphones are not an exception.  Consumers are looking for high quality headphones that can be used for a variety of purposes, and these fit the bill to a tee.  The Sennheiser company has prided themselves on improving this product based on the customer reviews on the previous model, the MM 450.  Some of the complaints about the 450 were changed on the Sennheiser MM 550 headphones to make them a more improved model!

    Like the MM 450 models, the MM 550 is an over the ear design.  Sennheiser did change the size of the over the ear cup so that the headphones were less bulky, but users have commented that they are extremely comfortable to wear, even for those people who might have a need for wider headphones.  Wearing them for extensive periods of time is no problem!    Having this over the ear design allows the headphones to block out a good amount of outside noise even without turning on the Noise Cancellation option.  However, if needed, the MM 550 headphones do come with NoiseGard 2.0 noise-canceling technology, which does reduce the sound up to 90%.  The headphones also come with an improved carrying case which does fit all of the included components in one convenient location, which is a definite improvement from the nylon bag that was included in the previous model.  

    So is the quality of these new and improved headphones the same as the MM 450? Most definitely.  While some users do comment that the volume leaves some to be desired because it does not go high enough, there are settings that can be changed within the headphones as well as the devices that you are listening to that will allow for a higher volume.  While the battery still seems to be an issue with some users in that it does not have that long of a use life before having to be charged, this is expected with any Bluetooth headset.  The MM 550 comes with a USB cable that can be used in many locations to charge the headset if you are in an area where a wall charger outlet is not available.  It does not take long to charge the battery and then you are back to your listening again!  These headphones also come with the same TalkThrough technology that activates the external microphone with just one button.  In addition, the headphones have an invisible microphone for taking calls as well.  If you are in the market for a high quality pair of headphones, look no further.  The Sennheiser company has made a name for itself for delivering great products, and though the price might be high, you will not be sorry that you bought this great product!

    Sennheiser MM 550 Noise Cancelling Travel Headphones Review

    With Bluetooth Technology

    This is a headphone that is incorporated with a Bluetooth feature that works effectively with the notebook or iPad. Additionally, it also supports the iPhone by offering a relatively seamless switch between listening to music and taking or making calls.

    A notable downside of the Sennheiser MM 550 Noise Cancelling Travel Headphones with Bluetooth is that they don’t provide enough volume. In addition to this, the manual that the device comes with leaves a lot to be desired, as it does not explain things in a simple manner that every one can understand.



    The Sennheiser MM 550 Noise Cancelling Travel Headphones with Bluetooth is a device that I would recommend to other people.

    Check the Amazon website here for more information on this product.

    Sennheiser MM 550 Noise Cancelling Travel Headphones Review

    With the Sennheiser MM 550 Headphones, there is a detachable cable that makes the switch from the Bluetooth in a simple automatic manner. This is a feature that makes the headphone to have a relatively easy effect on the airlines. It is charged with the world battery chargers via the USB port.

    There is another feature which is known as the Talk Through which allows the users to talk through the head Phones and hear what is going on around them. The head phone has been designed to be very comfortable and it cancels noise. The feature is incorporated with the Talk Through in that you can either switch the Noise Cancellation on or off.

    The quality of the sound is usually much higher when the device is being used in an environment that has minimal noise levels. The quality of sound that the device produces in general is very excellent. This can be heard on the crisp trebles and the booming bass that does not distort all the same. It has been designed using technology that will enable all genres of music to be enjoyed to the same extent.

    Sennheiser HD 650 Headphones Review

    Sennheiser HD 650High Quality Headphones

    Sennheiser HD 650 headphones have incredible audio, a strong and tough headband and comfortable, molded ear cups.

    These headphones are very expensive and require  pricey accessories to fully experience sound quality.

    The Sennheiser HD 650 is an audiophile's dream. It delivers audio that is at once crisp, rich, warm, and inviting. Yet its price makes it very hard to justify buying unless you're the most dedicated music fan. But if you can find the headset for twenty percent off or more, you'll be getting an incredible deal.

    Check the Amazon website here for more information on this product.

     Sennheiser HD 650 Headphones Review

    High Quality Headphones

    Sennheiser has always been known as a company dedicated to furthering the technology of headsets and this has made them a darling among serious music buffs and audiophiles. Because of this, Sennheiser can get away with charging very high prices for their very powerful and capable headsets. The Sennheiser HD 650 is arguably their greatest creation yet, but it is also easily among their most expensive headset ever made.

    Clocking in at over six hundred bucks, this is definitely not a headset for a casual fan. But it is refreshing to see that, for an audio purist, the price is justified. The sound quality is absolutely astonishing, with a gorgeous dynamic hi-fi sound thanks to the open ear cups. The bass is wonderfully rich and smooth yet still mighty. The connecting cable is a brilliant copper reinforced with Kevlar, making its handling noise incredibly low. The design of the headset is also very stellar, with ear cups molded to the ear and a tough yet very comfortable headband.

    Still, one glaring problem with these headphones is that they're of such a high quality that they truly must be played on a similarly good amp and music player. In other words, you may have to shell out even more money if you want to hear this headset in all its glory. Think of watching a blu-ray movie on a regular non-hi def television set and you've got the idea. For some people, getting a high quality amp and sound system simply isn't feasible, especially after plunking down over six hundred clams for the headset. But, thankfully, the HD 650 can be found for less than its MSRP. In some places, at the right time, you can save hundreds on this powerful headset. If this is the case, and you can find an equally good amp for a low price as well, you will be astonished at the incredible sound that can come out of these lovely ear cups.

    Sennheiser HD 598

    Sennheiser HD 598

    The Sennheiser HD 598 is so comfortable, you will hardly know you are wearing them.


    The price is a little steep, but well worth it. The adapter doesn't seem to fit on as many things as you may wish.

    Over all, this headset is a great piece to own; people seem to love it. They say it's a little tight when you first get it, but after a few days you couldn't be more comfortable with it on. It is great for sound and for wearing for long periods of time.

    Sennheiser HD 598

    Enjoy comfort like never before

    Sennheiser HD 598

    Sennheiser has long been known as the electronics company that melds affordability with quality in a way so that everybody, no matter their background, can enjoy top notch audio without breaking the bank in the process. So it goes with the Sennheiser HD 598  Headphones, the latest entry by the beloved company.


    Though the HD 598 is beautiful, looks are way down on the list when it comes to quality headphones. Aural capability is the order of the day here and, luckily, the HD598 definitely delivers on that score. The headphones come with Sennheiser's beloved “E.A.R.” technology, which stands for “Eargonomic Acoustic Refinement”. The sappy pun aside, this technology actually is quite grand. It is set up to channel audio signals right into your ear while removing interference and outside noise. Combine this with the similarly high tech Dufol diaphragm (which eases distortion) and you've got a sound system that can't be beat.


    Though sound is of the utmost importance when shopping for headphones, one must also think of comfort because, after all, the headphones will be pressed against your ears for long amounts of time. Thankfully, Sennheiser certainly took that notion into consideration. The ear cups are covered in a sleek and lush velour that makes them a dream to wear. The headband is also cushioned to further enhance the extreme comfort for the wearer.


    At first glance, one might think that the HD598 is bereft of extras and special features. After all, it only comes with an adapter. But the truth is that the headphones are actually chock-full of features that are contained within. In addition to the EAR technology, there is also a very advanced neodymium magnet system inside the set which further enhances the listening quality. Compressed cellulose fleece is also found inside the headphones, which works in conjunction with the Dufol diaphragm to eradicate distortion of all kinds.

    The Sennheiser HD 598 Open Circumaural Headphones may be the company's finest hour yet. With a massive amount of features all combined within a price tag that is under three hundred dollars, one finds it difficult to recommend any other headphones as of right now. Sennheiser has truly found a winner with the HD 598 and we can only look forward with baited breath to what the company will roll out next.

    Technical Info:

    • HD 598 audiophile headphones inspired by European sport sedans
    • Ergonomic Acoustic Refinement technology
    • Plush Premium metal mesh and sophisticated burl wood accents luxurious velour ear pads for long listening sessions

    Sennheiser RS 140

    Perfect for listening situations at home

    A with all of Sennheiser’s audio equipment development ventures, their divergence in to the area of developing wireless headphones has borne fruit with such models as the Sennheiser RS 140, which is truly a gem in the industry.

The headband is well-padded as well, allowing you to wear the Sennheiser RS 140 for hours at a stretch. However, some users have complained that when wearing the headphones for long periods, the closed-back nature of the ear cups caused them to get sweaty ears.
