I don't use "ear-buds" as they are not comfortable. I use the Sony MDR-7502
headphones for program listening. http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7378990783 They are small as headphones go but they are bigger than the typical Ipod or headphones sold with cheap small portables. They are comfortable and seal your ear so that external sounds won't bother you. The Sony MDR-7502 have a frequency response of about 60 Hz to18000 Hz. They can be found for about $40-$50. For shortwave, HiFi headphones are overkill and may even be a detriment. HiFi headphones were designed to reproduce full spectrum audio from around 20Hz to 20000Hz or even wider (CD's) which is the absolute maximum hearing range of a person with perfect hearing. Most people's hearing is no where near that good. In the case of shortwave DX listening, being deaf to high audio frequencies is not be a bad thing. Using HiFi headphones for listening to shortwave or even MW & FM radio stations will cause listener's fatigue. That fatigue is caused by the hiss reproduced by the HiFi headphones from the radio's internal circuitry and is especially audible at higher volume levels. The typical shortwave radio and MW broadcast's typical audio frequency range is about 100Hz to around 8000Hz (? - someone correct me on this). Anything you can hear outside that range will be N-o-I-s-E! Furthermore on shortwave, the band noise and static crashes are in the high audio frequency range which a HiFi headphone will probably emphasize in your ears. The result - listeners fatigue. One pair of headphones manufactured today that is designed for weak signal SSB and CW (Morse code) is the Kenwood HS-5 headphones. http://www.universal-radio.com/catalog/head/0357.html I use them when I need to pick out a whisper in the mud. Their audio frequency response is very narrow, 150 Hz - 4000 Hz, and I do not recommended them for arm chair program listening - IMO. But effective on occasions for hearing weak broadcast stations amongst annoying band noise and static crashes. My HS-5's are just another DX "tool". wrote in message oups.com... - header says it all.. long lastinig wires are the critical part RSVP to thread |
