Two Digital Wireless Headphones Reviewed - The Latest Trend In Wireless Technology?
Watching TV at night without disturbing others is probably the prime application for wireless headphones. Not being tied to a headphone cord is one of the biggest reasons for the popularity of wireless headphones. Yet in the past these headphones never really compared with traditional corded headphones in terms of sound quality and reliability. Mostly the transmission technology would degrade the sound and be susceptible to interference. Are new advances in wireless transmission technology able to cope with the drawbacks of the previous generation of wireless headphones? We will take a look at some of the most recent models of digital wireless headphones to see how they stack up compared to traditional corded models.
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 are used to from previous generation wireless headphones. Both models claim to transmit CD quality audio.
At first glance, the Sennheiser headphones are constructed as open headphones, i.e. sound from the headphone transducers will penetrate to the outside while the Amphony headphones are closed. Choosing open or closed headphones is a matter of personal preference. A closed model, such as the Amphony, will lower the sound level heard by others which is good when listening over headphones without disturbing others and also will block exterior noise more. Both models come with comfortable 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 offers one analog audio input, one coaxial digital audio input and one optical digital audio input. The digital inputs are useful when connecting the transmitter to a plasma TV for example which normally don’t have analog audio outputs anymore. The Model 2500 transmitter will automatically switch to the correct audio input by detecting which audio input has a valid signal.
Judging the sound quality of both models, the sound of the RS180 is on the light side with good mid range but a little low on bass. As such we feel the RS180 is suited for listening to vocals and light music. The bass response of the Model 2500 is more pronounced than the RS180 but still well balanced and not overly aggressive in any way. The wireless transmission itself no longer suffers from the drawbacks of previous generation models and the sound quality of both models rivals the quality of corded headphones. One limitation though is since wireless models are battery powered, they will never be able to achieve the same loudness as corded headphones hooked up to a good headphone amp. Having said that, both models achieve plenty of volume though, 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. 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.
