Digital Wireless Headphones Review - The Latest Trend In Wireless Technology?
Being able to watch TV at night and not disturb others has been the driving force of wireless headphones. In particular the benefit of not being tied to a headphone cord has led to rapid growth of wireless products. However thus far wireless headphones could never really match the sound quality of traditional corded models and the wireless transmission would be prone to interference and noise. Is the latest wireless technology able to remedy the problems of previous wireless headphones? We will take a look at two wireless headphones that both utilize the latest in wireless transmission to find out how these models stack up against traditional corded headphones in terms of sound quality and reliability.
We will review the Sennheiser RS180 and the Amphony Model 2500 both of which use digital audio transmission. In other words the headphone transmitter will convert the audio signal into digital data which is transmitted to the digital wireless headphones. The headphones then convert this data back to audio. Using this transmission technology, none of these headphones showed the static or distortion that we have gotten used to from previous wireless headphones. Both of these models claim to transmit true 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.
The RS180 transmitter acts as a support base for the headphones. When not in use, the headphones can be suspended from the transmitter. The transmitter offer an analog audio input, yet no digital inputs. The Amphony 2500 transmitter offers analog inputs, one coaxial digital and one optical digital input. As such the Model 2500 transmitter can connect to newer plasma TVs, most of which no longer have analog audio outputs. The Model 2500 transmitter will automatically recognize whether there is a digital signal present and switch to the corresponding input.
One of the most important aspect of headphones is the sound quality. The sound of the RS180 is on the light side with good mid range but a little low on the bass. Therefore the RS180 is well suited for listening to vocals and light music. The Model 2500 has more pronounced bass but still is well balanced and not overly aggressive. Neither model is suffering from the problems of previous wireless headphones and the sound quality of both models rivals that of corded headphones. Since wireless headphones are battery powered, they will naturally not be able to achieve the same loudness as corded headphones hooked up to a good headphone amp. However, in our testing, both models achieved sufficient volume, the Model 2500 a little 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.
