Line headphones, especially not tied to a wire have higher visibility. However, the traditional wireless headset may never match in sound quality and realiability cable headphones. The wireless transmission easy to produce the interference and noise. The new progress in wireless technology, the commitment to correct these shortcomings. We will take some of the most recent model digital wireless headset a, see how they stack up than traditional cable models. We will review SenHaiSaiEr RS180 and Amphony 2500 type. The two of those headphones adopting digital audio transmission. This means that, before the audio signal by the transmitter of the transmission, signal first converted into digital data signal, and then get spread. And then the resulting information broadcast headset conversion back to audio. Use this digital transmission, the two models do not show any hiss or distortion, and from our previous wireless model. These models have alleged that the transmission real CD quality audio headset. Looking, we immediately noticed, design for an open headphone, which means that, from the voice of the sensor can easily penetrate to the closing of the Amphony headset SenHaiSaiEr headphones. No any special design is better, it is a personal problem of be fond of of the state of the way. A closed design, such as Amphony, will reduce, this is a very not disturb others issue of high volume of listening to hear good of others. These two kinds of models are equipped with comfortable velvet ear cushion, suitable to serve as The support of The headset based snugly. The RS180 transmitters behavior. When not in use, headphones can pause from transmitter. Provide analog transmitter audio input, but no digital input. This is especially important, because the most modern plasma TV will no longer have the analog audio. 2500 type transmitter will automatically switch to correct the audio input, by detecting the audio input a effective signal. Judging two models of the sound quality, RS180 sound, light, is a good intermediate, but in the bass is a little low. So, we think RS180 is suitable for listen to sound and light music. 2500 type has the obvious bass response, but no aggressive and good balance. Wireless transmission itself is no longer a generation models of malpractice and the two models of the sound quality of the cable headphones as quality. A limit, although because wireless type battery power, they will never be able to achieve the same loudness, as cable headset connected to a good headphone amplifiers. However, in our tests, The two kinds of model achieve enough quantity, model 2500 more, than RS180. The RS180 2.4 GHz radio frequency signals. It is as high as four percent support transmitter headphones. Model 2500 5.8 GHz works, and support an unlimited number of headphones. In a 300-foot RS180 range specified by SenHaiSaiEr. In our tests, we were able to get a clean signal in indoor environment in which two models of 100 feet or so. This should be a lot for most users. The output of 2500 type transmitter, support further expand The business range. The RS180 have type 2500 15 hours of battery life left, provide 30 hours, every time The charging second emitter (RangeBoosters). RS180 wireless headset costs 300 yuan and 200 yuan for 2500 type.
