Review HD598 Sennheiser headphones - the valueable for listening to vocal or orchestral symphony.

Headphones belong  Sennheiser's professional line of nostalgic beauty and audio-class "audiophile".

Sennheiser HD598 headphones are as "open-back" and the head model in three 5x8 serries headphones Sennheiser's latest, including HD518, HD558 and HD598. HD598 is considered an upgrade, replacing the current mid-range headphones for the audiophile's been selling well - HD595.

The first impression with the Sennheiser HD598 is very eye-catching form with a tasteful design. Cream be coordinated with other key brown classic details give this headset a noble beauty. But do not use metal parts to reduce weight, but the HD598 provides a sense of certainty and careful design. The use of advanced materials velvet and leather in some detail on the headset contribute to a sense of hi-end.

Unlike its previous life Sennheiser headphone, HD598 with jack cord detachable . For those who fancy, prefer to upgrade the earphones cable, this is especially useful improvements. Cable comes to 3m in length, made of good quality OFC copper and coated outside with a very durable material, resistant to suppression, the impact of the environment.

Sennheiser claims they use Eargonomics standard friendly user in this new series. And first feel when wearing the trial showed that its claims are not mere marketing. Part ear-cup covered with velvet pad tight-fitting soft leather upper head and ears, feeling quite comfortable, not restrictive. Designed inside chamber music headphones are the company's engineers carefully studied with the aim of making people use headphones long without being tired.

Driver used in the HD598 is neodyum powerful magnets used in combination with diagfram two layers  Duofol and coil technology speakers with lightweight aluminum alloy in order to reproduce the detail and accuracy of sound in the highest level. Type used in the serries 5x8 driver is considered to be much improved than the previous 5x5's serries. These data reveal that, HD595 headphones are low impedance (50 ohm), very responsive (112 dB) and wide frequency range (12-38500 Hz).

Coupled with NuForce Icon HDP, immediately after "open box", HD598 has made an impressive ability to reproduce a wide open sound stage. The sound of the HD598 provides a fairly clear sense of an immersive audio space from in front of the listener rather than coming from behind like many other headsets. Perhaps, the design of a special chamber music by Eargonomic Acoustic Refinement technology of Sennheiser brings its apparent effect. Details of the audio and secondary audio attractive qualities is dominant, is easily found in the first field test of the headset.

After a period of " trial running", the sound of this headset was significantly better, particularly the bass range. The overall sound of the HD598 is rather balanced. We can say, HD598 has features very close to the superior products of Sennheiser HD650 or HD800. The inferior to the elder was probably just a little bit in the bass range and granularity. Compared with mid-range products such as HD580 or HD595, the HD598's sound is somewhat more attractive, rich in detail.

With rates of nearly 250$, Sennheiser HD598 is not small investment. But considering the relationship price / quality, then obviously this is a very worthy product of interest to the audiophile world, especially those who like listening to vocal or orchestral symphony.

Sennheiser HD 218 Review - Best price, fine quality

Sennheiser is known as a manufacturer of audio products with best quality now and HD 218 course does not rule out that, although this is only a mid-range headphones on the market and the under the lowest price of Sennheiser. HD 218 also makes users feel the quality can not judge from appearances. Powerful bass sound, compact design and comfort when using the strengths in the form of Sennheiser headphones HD 218.

This is the model headset was judged to be marginally better sound quality rivals more price range. Compact design, the size of the HD 218 has also brought to the user feels and runs as smoothly in the long run, even a first sample closed headphone.

Headphone jack is designed for 3.5 mm, consistent with the needs of users to use mobile phones, music players, iPhone and iPad, laptop.

Design
 
HD 218 headphones are samples taken on top form but are quite compact design and light weight. Capture the entire frame and the ears are made of plastic with dark tones. Plastic frame to take the rough with black, medium large in size and collapse between the two ears. Below have an extra layer of padding to keep the headset firmly on top and smooth to use. Like many other shooting headsets, Sennheiser still allows the user to adjust the width of opening of this headset by sliding the rim.

Create more comfortable feeling for users, both facing the ear frame was designed with a flexible, allow slightly sloping open to in or out. However, users can not capture the ears bend and fold back the same compact headset as some other line of Sennheiser Travel.

Like also Closed Headphones such as  HD418, HD 218 H428 or HD438, but the tiles have designs mid-sized and has no edges wrap around the ear. Thus despite long use, but users still do not feel hot or uncomfortable ear. Meanwhile, the sound from the headset has not been leaking to the external environment and influence the next.

Sennheiser headphones fitted to their standard headphone jack with 3.5 mm jack huge plastic head, head-standing form. Cable long sizes 1.3 m, using soft rubber material that can prevent tangle,but points deducted as well and not integrated audio controls. Size length that needs to use the HD 218 compatible with mobile phones, music players or laptops, but it is difficult to use with TV, computer or staging a PC.

Overall design, Sennheiser HD 218 can not create when they feel like simple designs, which use plastic materials lost seemed high, modern brand. However, the plus point in this model headset is very comfortable feeling while using the Closed headphones.

Musical performance possible

 Along with a sense of comfort during use, plus the HD 218 is a very consistent sound quality compared with its mid-range price. If you have used these headsets are used to cost under 50 USD, you will feel 218 HD-quality sound marginally better than other mid-range products.

The first impression is reflected in the bass. With the Hotel California by Yao Si Ting presented, showing the prelude music from the HD 218 will get you excited, fascinated with this song better. Bass section shows quite stocky, soft voice, rather than ringing or buzzing. Meanwhile, the voices of Yao Si Ting retains the detailed, well-defined. The highly negative light, pleasant feeling creative. In general, the reflected sound of HD 218 is considered perfect at the price of 890,000, consistent with soothing music taste like Pop, Jazz or Ballad, but with limited music scene, as powerful as Dance, Rock ...

However, is not without defects in the ability to perform the music of the HD 218. The main problem lies in the volume in this Headphones Closed headphones. Actually restrict the sounds around, but again the volume of the headphones makes the listener feel do not really climax.

Rarely do users try to turn the volume up on my iPhone, but a large amount when combined with the Sennheiser HD 218, the volume often have to stay above 80% to be able to comfortably enjoy your music.

However, that is the case quiet environments like the workplace, at home longer if used in noisy spaces such as train stations, railway stations, the largest volume level with HD 218 is probably not enough . Even with computers, the volume is not large enough sample of this headset also occur.

Able to demonstrate sound detailed and clear but the music shows in HD space 218 is not high, comes with the lack of ability to perform surround sound effects. Samples of medium-range Sennheiser headphones will fit the need to use to listen to music instead of the interests of the faithful watch mobile users.

Advantage

 
- Lightweight design, feels comfortable to use
- Demonstrate strong bass, strong with Dynamic Bass Sound
- Demonstrating the perfect musical with medium price
- Flexible design can keep noise and good sound
 

Disadvantage

 
- Material plastic
- Simple design, can not be folded to bring move
- Volume is not large enough

Sennheiser RS160 review- good headphone for your entertainment

RS 160 is type headphones traditional with big ears to hear, embrace the ear and good soundproof. The chassis is made from resin with the most detail to show through the translucent painted black. The extra details like the center or edges of the small belt headphones black paint makes the product attractive style, fashion more.

Sennheiser's wireless headphones use rechargeable AAA batteries, but the NiMH technology. Just twist the left ear protection in each and must be to expose the battery holder. Batteries NiMH AAA to the weight of the RS 160 is reduced more, meaning that users can easily find and replace batteries as needed. The design of the headset charger included for users to fully charge the battery directly through your headset without removing the battery charger separately.

Comfort is that users feel when using wireless headphones Sennheiser RS 160's. In the lightweight and can easily adjust the sizes of the rim cover is an advantage that this model provides headphones. However, the rim cover of the ear with a large buffer can make the listener's ears are heating up if bring too long time. This is a common drawback of the first cover headphones.

A point deducted in the design of the ears is a wireless arrangement makes the system off button users find it difficult to use. Position open source shortcut buttons in the middle two buttons to increase or decrease the volume makes the user more time to be groping to adjust the headset volume, avoid pressing the wrong and always turn off the headset off.

Comes with Sennheiser RS 160 is a wireless signal receiver is quite compact, round design style, with flat slightly translucent paint and shadow detail just like headphones. Users can now use the headset charger adapter to supply power to the transceiver or may add 2 AA batteries in just under the surface for use in cases such as when traveling and no available power source.

 The system button on the headphone

The receiver uses signals missing stereo jack 3.5 mm, allowing connection to most popular music player devices today. With a little pre-amp built-in, users can freely adjust the music volume from the transceiver to a headset or separate from the playback device. With the transmission technology Kleer uncompressed signal, the transceiver can connect with up to 4 RS 160 headset same time, at a distance of up to 16 m.

According to the specifications that manufacturers provide, these headphones can play music continuously for a maximum period of up to 24 hours. However, it is in standard testing conditions, the distance between the headset and the transceiver is fixed, the volume is also limited to a certain level. While the real test, Sennheiser RS 160 is in operation continuously for 20 hours.

 Transceiver signal included

In terms of features, RS 160 lost points when compared with some rivals such as Sony MDR-price range NC500D by noise reduction and anti noise features . Although located in the upper range of Sennheiser but at a price 159 $, the omissions, this feature makes few buyers in mind.

With RS 160, Sennheiser want to offer users a wireless headset with excellent audio quality and impressive than a product are integrated so many features associated with the ad and excessive flattering.

Usually, one of the weaknesses of wireless headphones compared to traditional wired headset as audio performance possible. The removal of the wire to help users feel comfortable using the application, more dynamic, but the technology signals via radio waves or bluetooth also makes the sound quality transmission is reduced drastically. However Sennheiser chose Kleer wireless technology, capable of uncompressed audio transmission enables efficient wireless audio performance is not diminished compared with the original signal.

Unlike Bluetooth A2DP, Kleer full use of bandwidth saving 16-bit, 44kHz, uncompressed quality of the original CD. The combination of the two large drivers gave large differences in sound quality compared with other wireless products, the RS 160 bass not only depth but also much more accurate. Moreover, the sound also shows a sharp, crystal-clear even in the high frequency range. Therefore, the warp dance music or rock music intense is the most appropriate thing to RS 160 performances. The audience felt the detail and sound quality from luxury models to test this headset with music and rock of Metalica.

With price 159$ of RS 160 can be expensive, but with the ability to demonstrate sound and highly Kleer wireless technology, Sennheiser headsets are a form of wireless headset is very attractive and options worth today.
