You can have up to four receivers per transmitter. The range is about 30m so you can visit the toilet and still hear what’s going on. Receiver: Small pocket clip sized transmitter with 12 hours of battery life driving standard headphones.Power: 5V/1A/5W plug pack, which provides power for the transmitter and to charge the receiver.Inputs: 3.5mm analogue and digital optical (TosLink).They come with MX 465 cabled buds renowned for audio quality without ‘trickery’. The Flex 5000 ($349.95 as reviewed) uses the same transmitter (base unit), but it has a separate portable, battery-operated receiver that you can plug in any 3.5mm headphones. The entry-level is the RS 5200 with a stethoscope earpiece, and it is the lightweight way (not over the ear headphones). Sennheiser offers a variety of solutions and pricing. On those points alone it is the best solution. To my knowledge, there are no other TV headphones with separate left and right volumes (as each ear is different) and clear voice EQ. Sonova Holding, based in Switzerland – a global provider of medical hearing solutions – now own its consumer audio businessįirst impression – Sennheiser Flex 5000 Headphone receiver/transmitter Sennheiser (Est 1945) is a German privately-held audio company specialising in designing and producing a wide range of high fidelity products, including microphones, headphones, telephone accessories, and aviation headsets for personal, professional, and business applications. $349.95 (black) plus your choice of cabled headphones (free shipping), but shop around as we have seen them for as low as $229 inc delivery. TV headphone site and Sennheiser Flex 5000 Headphone receiver/transmitter Product site Sennheiser Assistive Listening wireless TV headphones Website The most critical part for clear speech (intelligibility) is a narrow band from about 1-4kHz. So clear speech is 150Hz-6kHz (men) and 350Hz-8kHz (women). For example, ‘s’ (5-7kHz) becomes Sssssssibilance (hiss) in vocals. Each ear is different, too – stereo (sound from both ears) is unequal.įrequency loss usually means that bass sounds muted or muddy, and treble disappears with consonants like j, u, z, f, s, and th simply unintelligible. Typical hearing loss means low-frequency response levels creep up from 20Hz to 1kHz, and high levels drop from 20kHz to as low as 8kHz. An average adult with good hearing is closer to 150Hz to 17kHz. Perfect hearing is from about 20Hz (Hertz – you can’t hear, more feel, this low bass) to 20kHz (kilohertz – again, you cannot hear this, but it fills in the sound, making it crisp and directional). Hearing impairment is more about losing specific frequencies. Upping the TV volume helps a little, but you are still missing the nuances. As they get older, that increases, and at 35dB, you are considered hearing-impaired. Turning up the volume with other TV headphones is not the answer The science of hearing As far as we can find, Sennheiser Assistive Listening wireless TV headphones are the only ones to do that. It is about selectively reinforcing specific frequencies you have lost and overemphasising clear voice and speech frequencies. You see, excessive volume is not the answer. That may work for you, but it is hell for non-impaired listeners. Why? Well, as you become more hearing impaired, you tend to turn up the volume. Sennheiser Assistive Listening wireless TV headphones are the best solution we have found for TV watching. That, unfortunately, means we find it harder and harder to hear conversations and voices on TV. As we get older, we start to lose the full 20Hz-20kHz hearing range.
