New advances in wireless technology promise to remedy these drawbacks. We will review two models of wireless headphones which utilize the latest transmission technology to find out how these products compare to traditional corded headphones.
In this review, we will take a look at the Sennheiser RS180 and the Amphony Model 2500. Both of these models utilize digital audio transmission. Simply put, the wireless signal that is broadcast by the transmitter will undergo a conversion process. Then the resulting information is broadcast to the digital wireless headphones and converted back to audio. Using this new wireless technology, none of these models exhibited the noise that we order online cialis are used to from previous generation wireless headphones. Both models claim to transmit CD quality audio.
Looking at the headphones, we immediately noticed that the Sennheiser headphones are designed as open headphones which means that sound from the transducers can easily penetrate to the outside while the Amphony headphones are closed. Choosing between an open and closed design is a matter of preference and there is no way to state that any particular design is better than the other. A closed model will tend to reduce the sound level heard by others which is useful when listening at loud volume. At the same time a closed design will tend to attenuate exterior noise more. Both models are equipped with soft velours ear cushions and fit snugly.
When not in use, the RS180 headphones can be suspended from the transmitter which acts as a support base. The RS180 transmitter offers a regular analog audio input but no digital audio input.

The Model 2500 transmitter will automatically switch to the correct audio input by detecting which audio input has a valid signal.

As such the RS180 is most suitable for listening to vocal racks and light music. The Model 2500 has a more pronounced bass response, but in no way aggressive and is well balanced. The wireless transmission no longer has the problems of older headphones and the sound quality of both models rivals corded headphones. The only limitation is the fact that wireless headphones are powered by batteries and thus will never be able to blast the same volume as corded headphones connected to a good headphone amp. However, both models were able to achieve reasonably loud levels, the Model 2500 more so than the RS180.
The RS180 broadcasts it’s signal at the 2.4 GHz frequency. It supports up to four headphones per transmitter. The Model 2500 works at 5.8 GHz and supports an unlimited number of headphones. The range of the RS180 is specified at 300 ft by Sennheiser. In our testing, we were able to get a clean signal up to around 100 ft with both models in an indoor environment. This should be plenty for most users. cialis without prescription The Model 2500 transmitter has an output that supports secondary transmitters (RangeBoosters) to further extend the operating range.
The RS180 has a battery life of around 15 hours the Model 2500 offers 30 hours per charge. The cost is around $300 for the RS180 wireless headphones and $200 for the Model 2500.
