Out of all the pocket radios we've tested that do not have built-in speakers, the Sony SRF-M37W Walkman Radio has THE BEST AM radio reception. Customer recommendations brought this radio to our attention. Our tests confirmed that this compact, easy-to-use radio has great AM sensitivity. However, if you are close to an AM broadcast antenna you may notice some bleeding into other adjacent stations on the dial. FM reception is comparable to our other fine pocket radios. Features 20 station presets (5 Weather, 10 FM, 5 AM), direct weather band button, local/distant (DX) switch for improved reception, hold switch to prevent accidental station changes, battery indicator, and LCD Digital Display with clock. Stereo headphones and belt clip also included. Exceptional battery life of over 40 hours on just one "AAA" alkaline battery (not included). Dimensions: 3.375" W x 2.5" H x 1.31" D. Weight: 3.3 oz including battery and belt clip.

High Sensitivity, Great Value.

Top quality, amazing!

I like the small easy-to-carry radio. The large head phones defeat the compact feature. Simple earbuds would be much better with the super small radio. I'll probably order another one in the near future though.

Nothing like I had expected. I wish I had not purchased this radio.

A fantastic little Walkman for AM/FM/Weather reception. Works great at 6,000' to 11,500' along the Front Range of the Rocky Mountains in Colorado. Very good battery conservation with average AAA alkaline commercial brands. Would recommend it for CONUS or EURO travel. Priced right and well worth it!

There great, do you still carry them, I might just get another one. I have four Walkman’s and one Panasonic, that eats batteries.

I love this radio. I'd give 10 stars if I could. Use with rechargeable batteries and you'll have forever.

I ride my bike daily in the summer and needed something small and compact to take with me. This little am/fm radio is ideal. Has great reception and hooks right onto my workout shorts. Uses one little AAA battery and lasts a long time. Highly recommend this unit if your hooked on talk radio like me.

I got its predecessor about 5 years ago and it's still going strong. I bought a new one because I like it so much. The contacts for the buttons have not worn out and I listen to this radio every night, switching around. It's easy to program the buttons. I like the number of options for FM. I live near Detroit. I can pull in AM from Toronto, Boston, New York and Philadelphia, Richmond, VA, over in Iowa, and down to Kentucky at times. It's a great little radio.

Just bought my second Walkman. First one is a few years old but still going strong. Needed another one for travel and my second home. Great little radio, and single AAA battery lasts a long time.

Excellent product. Have used for 4 years and love it, very sensitive to water damage but very durable other wise. Have dropped it while running numerous times without damage. Will continue to purchase if available.

I love this handy, little AM/FM radio. Use it every day going back & forth to work on the train and when I walk my dog. I especially like the "lock" so I don't accidentally change the station or turn the radio on or off. It locks the station in place, but you can still adjust the volume. I also find the weather band a plus.

  • 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.
    — Gary B., San Francisco, CA
  • 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
  • I have had only one, thank the lord, occasion to use this in and emergency situation and it worked flawlessly. Only one in the area with radio for two days of power loss... Thank you CCrane!!

  • This radio is totally fantastic!!! It will provide service in any condition and works as engineered and advertised. I am going to order more units for all family members.
    — Glen B., Bethlehem, PA
  • This radio is wonderful. Small but powerful. Several years of service and no problems.
    — 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.
