Best Uses
Crystal set construction.
I purchased two of these because I was intrigued. They were listed as a crystal earphone and they LOOKED like a crystal earphone, but why were they being sold at C. CRANE? They also get mixed reviews. As soon as my order arrived I got out a crystal set and sure enough they worked perfectly. For those who don’t know, a crystal radio has no power source other than an antenna. It uses a tuned circuit and a diode, and needs an earphone or headset of very high impedance. Therefore, a “crystal earphone” is required to hear anything at all. They are extremely sensitive to the tiniest electrical current. As for the mixed reviews, I believe people are using them on transistor radios. A transistor radio is “looking” for an impedance of 8 to 32 ohms at the earphone jack. A crystal earphone is rated at 2000 – 4000 ohms. They have no DC resistance at all. As far as the radio is concerned, there is nothing at all connected to the headphone jack when a crystal earphone is plugged in. I wouldn’t dare plug mine into a transistor radio. I have spent time and money trying to find a decent crystal earphone, as the quality of these things has been horrendous in the last few years. I was very glad to see C. Crane selling them. I don’t know why there is a stereo plug on them. I think the implication is they are “regular” transistor ear plugs. They are not.

I purchased (3) of the large earphones and all three were found to exhibit the same characteristics. First, they required more volume to hear and then the sound was tinny. Second, after about 5 minutes they (all three) would go dead. I tried them on portable radios and recorders they were still dead. After getting disgusted with them I tossed them and gave up. About an hour or so later I tried them again and they were working but, same story five minutes and they were dead again. These earphones are worthless.

  • This WiFi Antenna is hands down the best. It allows me to connect to a business almost a half mile away. Two months time and this baby paid for itself. I am a very happy with my purchase.
    — John A., Mill Valley, CA
  • This radio deserves five stars because it sounds great, the ease of use and preset stations. This radio will become your favorite radio, also backed by great customer service if ever needed, thank you very much.
    — Pete P., Santa Rosa, CA
  • This is an excellent internet radio. I have had the unit playing constantly from the time I received it. Excellent sound for such a small unit and the remote works wonderfully.
    — James H., Richmond, BC
  • Good sound, lightweight and comfortable; not too tight on the head. I like one feature; it doesn't tell you where to place the speakers, left side or right side.
    — Harry W., Manassas, VA
  • I purchase this product specifically for AM recordings and it has worked superbly. I wanted to wait awhile before I gave my opinion on the product. It has worded exactly as advertised and more.
    — Jack L., San Pedro, CA
  • Very nice, economical home lighting. If you're used to the white light of fluorescent bulb replacements, these will offer the same type with no toxic ingredients or damaging UV radiation.

  • This antenna does work well; however placement and the shape you have it bent into is very important. I live about 70 miles away from Toronto and receive a lot of Toronto FM stations static free with the FM reflect.
    — Thomas S., Buffalo, NY
  • I'm not sure how I gone this far in life without it. I just love it. The best sound ever from an AM radio.
    — James G., Springfield, MA
  • This device is awesome. As a contractor, I can not access my customer's network for security reasons. Now, with my office on the second floor, I can connect to a WiFi hotspot 1.5 miles away and my signal strength is strong!
    — Robert S., Tabernacle, NJ
  • I just received my EP radio yesterday. I'm totally impressed with the old school simplicity and the modern day sound quality. Thank you, C.Crane!
    — David C., Raleigh, NC

    — William B., Litchfield, IL
  • Just received this little jewel... did not open the manual and I was listening to NPR within minutes... no kidding. I'm a radio guy and the audio is great and look forward to a lot of great listening.
