I bought this for use with my phone so it would be easier to listen to music. It does the job pretty well, but you can't wander too far away from your phone. I usually have my phone in my purse, so that's not a huge problem. It works with the remote, I can adjust the volume or skip tracks and so on. My display doesn't show anything though, but I don't care too much about that. I only mention it because it may be a dealbreaker to some. There's probably an easy fix for this, but I am really not bothered by it, so I haven't looked it up. I also use it to make calls, and according to people I talk to on the phone, the sound quality is about the same as if I was just using my handset.

I sought out a2dp headphones and have owned this product for a month or two and use it with a Treo 680.
(1) Never had a "necklace" style bluetooth and, while I'm trying to get used to it, the little plastic pieces that make the "rope" into a necklace BROKE.
(2) The thing keeps shutting itself off after 5 minutes of use -- enough to make me want to return it. JUST AFTER the 30-day return policy.
(3) Even after adjusting the earbuds to fit, they fall out of my ears after 5 minutes.
:(

My friends complained when I used this as a phone headset. I could hear fine, but they didn't like the call quality.

I've used this with two phones now, and it works well with both. My current is the LG VX8350 and it connects and works with no problem. The stereo sound is great and the earbuds are very comfortable. The charger is light (contrary to a previous reviewer) but its always a hassle to carry a charger. The unit lives up to the 6 hour talk time (about the same for music listening) so I can't complain even though I wish for a longer battery life. There are more than 6 hours in my days.

Paired it with SonyE. W710 with no problem. Sound quality is pretty good. Not as good as the wired headset but good enough. Battery is good, at least 5 hours. The earbuds would fall if you don't wear them over the ear. The biggest problem is that if my phone is not in my shirt pocket at least 3 inches from the pendant, like say in my pants pocket, it will be nearly impossible to listen to the streamed music. It keeps losing the signal if there's anything in between the phone and the headset pendant. I'm not sure if it's my phone or the headset but I have a S.E. W710 walkman phone. You think they would work well together.

I bought this to use with my LG VX8500 because I was sick of dealing with over six feet of wires, with jack adapter and the actual headset, to
just listen to my music.

My first complaint is about the battery. It does not last for six hours, not even close. In fact the little battery life monitor on the LED screen will, at some point in time, jump from being 3/4 full to having enough juice left for five minutes.

Second, the whole necklace design is awkward. Quite often the strings attached to the earbuds will get tangled underneath the thread the forms the necklace, this makes it much easier for the buds to fall out of my ears.

In fact that's my next complaint, the ear buds suck. None of the three sizes they sent with the headset would stay in my ears. Just the vibrations of driving on a bumpy road, or walking was enough to knock them loose. This REALLY ticked me off. Nothing I did would make them stay in there, even jamming them into my ear canal. (Which I do not recommend, it drastically increased the pressure in my ear canal and it felt like my ear drum was going to pop.)

Finally, the sound quality is not that great. It's most noticeable on heavily percussive songs because the drums just sound like they're being struck with brushes instead of sticks.

And there's no bass to speak of, none at all. After using this headset even the bass on my car speakers is enough to bother me now, and they're just normal car speakers.

My Sony-Ericson HBH-DS970 has worked fine with my Treo 650 for more than a year now. The problem is it keeps failing. I keep exchanging it under warranty but it's a hassle and I'd like to find something more reliable. I use my headset while riding my bicycle and need something like the DS970 with earbuds. Cans and bike helmets don't mix.
Much of the time, I just leave the earbuds out but set up my Treo to auto-answer on the 2nd ring. All I have to do then to take a call is stick an earbud (either one) in an ear and say "hello" once it picks up.
My only other complaint about the DS970 is that the battery life isn't long enough when I'm listening to music or a book on tape. When I'm on a long trip and won't be jostling the ever so fragile headphone jack on my Treo, I plug in a wired headset. When I can't do that and want to be able to listen on and off throughout the day, I've learned to power down the headset at times when I can just as easily answer the phone without the headset, i.e. when I'm not driving or riding my bike. I really like the way it pauses the music when a call comes in. The music quality is acceptable for what it is.
Tomorrow I'll call and get my DS970 exchanged once again but I need something similar that's more reliable.

It's OK. But it's not as good as it should be for that price. It sounds good, but the wire gets "messed up" & "tangled up" easily. Hard to put on, and is not too "stylish. But It works, so that's what counts.

The music quality is absolutely terrible--it sounds like a cheap toy. Stay away from this headset if you're looking for something to stream MP3s from your phone or other bluetooth device.

Was looking for a "small bluetooth stereo headset" to use with my Treo.
This product is perfect in every way.

Recientemente compre este manos libre, me gusta mucho escuchar musica y el poder evitar tener Telefono + ipod era lo que buscaba, tengo un K790a el cual se escucha bien quizas un poco bajo para mi gusto, el ML se acopla rapido al telefono, como manos libre no me quejo, permite realizar y recibir llamadas, cuando la llamada es recibida en la pantalla te aparece el identificador de la misma,, como reproductor de musica tiene su gran debilidad y es la calidad del audio,, el equipo no posee reproduccion para sonidos bajos, en el telefono tuve que configurar el equalizador sin nada de agudo para que se pudiera escuchar mas o menos bien, de lo demas posee buen volumen y te permite controlar la musica sin tocar el telefono,,gracias

very use full item for someone who could use it. very well made, very comfortable and good sound. you hardly notice it around your neck.

I use this with my phone -- Sony Ericsson w850i. Now whem i use the stereo buds that comes in the package -- sound quality is pretty good. I also tried it with Sony MDR-EX81LP Bud-Style Stereo Earphones -- and it sounded even better.

However this bluetooth baby is a different storey altogether. Sound quality is noticably (U'll have to be deaf no to notice!) lower. There is no BASS (forget Mega Bass). Further you notice that the range is distinctly lesser.

If you listen to more that 2-3 hours of music the battery will die on you, And it ain't fun carrying arround the charger. If you use this while jogging, well connectivity will go on and off quite often.

Also the functions like controling volume, fwding tracks will not synchronice between the devices too well.

However it is quite attractive accessory to wear. Operations are simple.

So if you want a simple wireless device to answer calls, and may be listen to music once in a blue moon, you may like this. However if you'r a serious music lover -- STAY AWAY FROM THIS!

I am using the DS970 with a SE K790a phone and so far it has been great. For comparison purposes I used a set of Sony MDR-NC11 to compare earbud sound/noise cancelling qualities and SE HPM-82's for remote/handsfree functionality. Using those two leaves you with almost 8 feet of wires and three modules to contend with, the DS970 got rid of that. The volume is louder with the DS970 vs NC11, although the noise cancellation is not as effective. It still however blocks out the majority of ambient noise, and works well in NYC subways. SQ wise is on par with the NC11's though don't expect audiophilic quality (remember it was made for noisy environments). The silent hissing is not as pronounced as it is with the NC11's. For remote functionality, plusses are the backlit display and positioning of the controls (somewhat similar to the stick remotes found with Sony's MD walkmans). Unfortunately it does not have a clip and dangles freely. The mic isn't very good compared to the HPM, most callers complain about sounding "far", though reorienting the mic does help. Battery life isn't much of a concern for me, though 6 hours is plenty enough (the phone will only last for 4 hours of music playback with a full charge). The battery indicator is deceptive, showing full most of the time (~3 hours) then dropping rapidly afterward. No problems with the charger as the phone charger can be used as well (a plus of using a SE phone). It is more sensitive to interference than standard BT devices, and you will notice it (music starts clipping/dropping). Overall it is great for those who use their phones as a music player and wear ear buds all the time.

Sound volume is low and indistinct. Increasing volume does not make it easier to understand, just louder. Does a fairly good job of limiting outside sound.

Lanyard style can be inconvenient. Earbuds can be hard to insert when you get a call. Fob on end only display caller's number, not the programmed name.

Other side of line frequently has problems with hearing, microphone doesnt work well.

Like most bluetooth devices, lacks a user friendly on/off mechanism to decline using headset when it isnt convenient. User must go through the disconnect or power down process to use phone handset instead.

Overall, not a purchase I would recommend. Reconsider your desire to have earbuds.

This unit pairs great with my T-Mobile MDA, laptop, and Motorola DC800 music streams, switches flawlessly between calls and playback, supports voice dial and compatible with ms voice command. The battery life is only under 6 hours for music listening and needs improvement (consider getting 2 headsets to double the playback time!)

me compre uno y lo uso con mi motorola q y funciona perfecto, cargr la pila, habilitar el bloetooth en el telefono y encender este equpo y ya podia oir muy bien la musica y contestar llamadas.

I purchased this unit as one of the few stereo bluetooth headsets avaialable in mid summer of 2006 to use with my Motorola Q. It is a great headset, with great sound isolating (passive) properties due to the very comfortable ear buds. The audio is great, and the unit automatically puts your music on hold when a call comes in on the cell phone. You can also link it with a separate cell phone and MP3 player. I purchased a separate one for a friend with a QTeck phone, and was able to get and install drivers for that phone to acheive full functionality (althought the Qteck was not listed as being compatible.
My only complaint is the charger. As is Sony's habit, they changed charger connections with this phone, so the older charger tips do not work. The supplied charger (a CST-61, arrived with European prongs, and an adapter. It is a bulky and heavy unit. Sony support has been unwilling to provide a list of compatible phones that this charger will support, as I would like to get a USB charger for the unit (the input voltage is 5v, so a USB charger should work).
