Question: Can you lock the keys so you don't accidentally change the station?  Is the volume cont. position to avoid accidentally moving?
Document: I bought this radio to wear around the house and yard while doing chores. I like the station presets that let me find my favorite stations quickly. It's a little bulkier than I would like. My main complaint is that while it has a "lock" switch that prevents you from accidentally changing the station or turning it off, the volume control is a knob that can easily be bumped and changed and is completely independent of the locking mechanism.
Sony S2 Sports Walkman Digital Tuning Weather/AM/FM Stereo Armband Radio (White)Had to read the directions to do the basic set up for the clock and radio stations. Has a lock that keeps it set the way you have it so that you don't accidently turn it on while it is being stored and waste the battery. Also locks on to the station and keeps it there, just switch the lock tab and press the button to change the pre-set channels.
Sound quality is good although hard to find or pre set stations. I keep it on my belt and unless you lock the keys, the radio turns off if you bend over.
Reception is fantastic, and the volume is very good. The lock feature is great, because I can throw it in my bag and now worry about it turning on and draining the battery. It also looks like it might actually be an MP3, even though it isn't. An all around great running buy. Too bad it is not rechargeable.
Purchased this product keeping in mind the Sony quality for audio devices but was a bit unhappy that the product did not match my expectations.Pros:1. Manual Locking (Does not lock the volume)2. Sturdy design3. Weather BandCons:1. Supplied Headset does not reproduce the best audio2. At lowest volume setting, the product plays audio on right side only and then as volume is increased the audio play on the left side (This may be an individual product defect)3.
I have been using this radio for over a year at the gym. It has served me well, i suppose, but the volume controller recently broke off leaving me unable to change the volume and making the product basically useless :( I am also frustrated by how quickly it "eats" batteries despite my buying rechargeable AAA batteries. It is also bulky and the reception is not great, although that may be the result of it not having an external antenna.
Needed a radio to workout with in gym to block out talkers.Works great inside building with good reception.Can preset stations on it and easy to change with a push of a button.Have dropped several times ,just put battery back in and keeps on playing.Stereo headset,good volume,good reception and light weight.Clip can be used on shirt.A lot of radio in a small package..
Crappy reception. I can't get major NYC stations in NYC. Also, the volume button is in an awkward position: with the radio strapped around my left bicep, the volume dial is on the side closest to my face, which makes it hard to manipulate with my left hand. It's just awkward. Buttons are not intuitive. It fits very well though.
I bought this after searching futilely for a small mp3 player with am/fm radio. Since I listen frequently to radio I decided to go with this radio-only product.My main complaints:1. Size & Shape - not very compact and the curved shape is awkward if you decide not to use the armband configuration (it also comes with a standard belt clip)2. Design -- the volume wheel is poorly placed so it is prone to accidentally getting turned up or down suddenly3.
A great product for working out. I love using it on my power walks where I can easily change channels. The music reception is excellent. I'm very pleased.
Answer: There is a lock switch that keeps everything locked in place. The volume control is in an out-of-the way place.
