• Lightweight headphones with comfortable, adjustable headband
• Open-air design negates undesirable resonances for clear sound, allows outside sounds to pass through headphones
• 30 mm diameter drivers deliver deep bass
• Sony Acoustic Turbo circuit enhances low-end response
• Long 3.3-foot, Y-style cord

Lightweight open-air headphones are comfortable to wear, even for extended periods. The 30mm diameter drive units are larger than most headphones for noticeably deeper bass, lower distortion and wider dynamic range; frequency response extends down to a low 18Hz. The Sony Acoustic Turbo Circuit makes for high efficiency and gets high sonic output from your portable stereo - plus it extends bass response.

These Sony headphones are lightweight, economical, and comfortable. The MDR-101LP stereo headphones have an adjustable, overhead headband which allow you to fit them perfectly to your head's shape. The open-air design removes undesirable resonance by allowing outside air to pass through the headphones; the result is a better sounding headphone. The thirty millimeter drivers deliver deep bass. The Sony Acoustic Turbo circuit is included for high efficiency; it gets high sonic output from your portable stereo, and extends bass response. Put together, these two features help counter the tendency of headphones to sound cheap and bass-low. The long, one meter (3.3 feet) Y-style cord allows for ample movement and separation from the sound source.

What's in the Box
Sony MDR-101LP Headphones.

I have a cheap $15 mp3 player and when i'm playing it full blast through these Sony MDR 101 headphones sometimes its still not loud enough. I recently got an ipod nano and it still doesn't go loud enough, in fact its downright quiet with some material. I ordered some AKG k24p's which are supposed to be very efficient(play loud at a low volume setting) and sound very good. I've had these Sony's for over 3 years and they're still running strong. I remember my friend got a pair of $200+ Bose headphones the kind that double as outside noise insulators and i thought my Sony cheapo's sounded a lot better. Especially in the highs, his Bose's sounded muddy to me. If I'm walking through town with the Sony's on I definetly hear the traffic, construction etc.. In fact it may be a lot louder than the music, depending on what the source of the noise is and how loud the music is.I give these Sony's a 5 star rating for sound and a 2 star rating for efficiency(they don't go loud enough). So since i like the sound so much for the money i'm rounding up to a 4 star total. For the money a great deal but if you're listening to an mp3 player it may drain the batteries pretty quick and not go loud enough. My mp3 player goes for about 2 to 3 hours on a full charge with these headphones!I'm hoping with the AKG k24p's my battery will last longer and the music will play louder.lastly, for a portable walkman radio these headphones go plenty loud enough and sound great but for my mp3 player I would rate these headphones as follows for listening to live grateful dead mp3's (store bought mp3's may be louder): 25% of the music is loud enough, 50% of the music has barely adequate to not quite adequate loudness, & 25% of the music is just too quiet to listen to outdoors.

Good sound, reasonable price. Would recommend this product to anyone who does not need an extra long cord.

The sound quality of the headphone is very good but I was very disappointed since the cable was so short (around 36 inches/ 90cm). I was struggling to hook it upto your computer and sit properly on the chair. Infact I could only use it either on a portable CD player or sitting on the floor near my PC to be able to listen music through it! Also, please note that although the headphone is of Sony brand, it is made in China and not (as I thought) Japan.

Overall conclusion: Good sound quality but very short cable. Please consider the cable length which can bother you espically when using it on your computer.

I used ReadPlease - a super program that reads back anything you past into it - to edit my novels. I enjoy the headphones because it keeps me focused. I was using the earbud styles (...)and running through them because they just too flimsily made. Plus, when you are editing for 13 hours straight having the buds in you ear begins to make me feel like I have earaches.

These are SUPER. First, Sony -- enough said. They are VERY lightweight. I often forget I have them on, so when I am going for long hours, these are so easy. They have nice long slid adjustments so they will fit any head in comfort.

But comfort means nothing if you are getting muffled or distorted sound. Not that case. I love is the deep, rich base, yet the treble is pure, too.

So these are more than worth the price, giving you real comfort and sound for pennies.

Well, I needed some new headphones. I tried the UR5 from Koss. The sound quality was alright, but they could BARELY be heard. I found these, thinking Sony, would make headphones with better and louder sound. I was right.

The good news is that the sound quality is excellent. Sony headphones always seem to have more punch than other Koss, RCA, Panasonic, and other brands of headphones. The bass and treble are clear, and bass is pretty deep as other $6 headphones I've tried. I would have enjoyed the headphones that came with my player (SLSV570), but they were uncomfortable, and I mean VERY. These are pretty comfortable and lightweight, as the box explains.

The bad news is the overall durability of these headphones, which is a big minus. I've been though two of these, yet the third ones haven't broken yet at all (keeping my fingers crossed).

The price is very reasonable and very cheap, and I wouldn't have a problem buying another pair, because of their cheapness.

Overall, these headphones add a punch to your music, and the volume is loud for those quiet CD players.
