Sony SRS-P7 Passive Speaker System with Stereo Mini-Plug Input

I absolutely love these speakers as they require no batteries and are easily portable... These are basically the best alternative for people who hate wearing headphones (such as myself) unless when traveling by plane, train or bus (as using headphones is the polite thing to do, really no other choice in the matter)... The funny thing about this speakers though... i remember talking to my cousin one day, about how i had wished there were speakers that didn't require any batteries or charging than he told me he had a pair that did just that... i was shocked! (years ago at the time)... i also remember being out on the saco river kayaking one day with my cousin and he told me that they still work even when they get soaked by water... then he just outright dunked them underwater, took them back out and shook the water out of them and turned his ipod touch on and they still worked with no quality degradation whatsoever!... now that's awesome! Personally, i think that sony should have put a disclaimer of some sort somewhere on the product saying "Disclaimer: Results may vary dependent upon the device the speakers are plugged into"... because that's really the honest truth right there... as i've tried using these speakers with a ton of electronics i own and they were either a hit or miss... so i'll list right here what i've tried the speakers with... Works Good with... + Mp3 Players... Creative Zen 2gb, Ipod 80gb (5th Gen), Ipod Touch 4... I'm pretty sure that just about all mp3 players should work good with these speakers... so long as you don't expect thumping bass and very loud music (that's not what they were intended for) + Cd Players + Cassette Players Works Bad with... - Phones... Droid X, Iphones, any phones... just about every phone my buddies and i have tried out, you could barley hear any audio at all! (sounded like whispering)... why they don't work well with phones, i have no idea!... don't even bother using / buying these speakers if you plan on using them with your phone (better off using the internal phone speaker instead, or buying battery / wall outlet amplified speakers) - Laptops... Macbook Pro, Toshiba, probably any laptop... same situation as the phones, they don't seem to register, and sound like a whispering level... so your better off with battery / wall outlet amplified speakers - Xbox 360... tried plugging these into my 3.5mm mic / speaker adapter to no avail... just like the phones and laptops couldn't make out peoples voices at all!... but when i used a pair of wall outlet powered speakers (Logitech z130)... i could pick up everyone's voice on live unbelievably!... because i swear when you put voice output through the tv only... your not hearing everyone's voice as you should while playing on live, like you do with some battery / wall outlet powered desktop speakers i hope this review of mine was helpful (for at least some of you)... for me not having to use headphones for my portable audio devices lacking an internal speaker is a must!... i use my Creative Zen 2g (that has a built in speaker) for biking, hiking, walking... since it's so small (has just enough songs on it, even though by today's standards, 2gb is nothing)... and use my ipod 80gb for outside with the sony speakers on my backyard patio... than when i'm in my house i use these sony speakers with my ipod touch 4 for internet radio streaming (pandora, slacker, etc)... audio quality is plenty a good for the size of my place both inside and out... and the best thing is when your having a party that's running into the wee early am hours... you never have to worry about the music volume level going up abruptly disrupting neighbors, because we all know how loud some drunks can get especially when it comes to yelling over LOUD music!... lol... so to sum it all up... these speakers are a WIN WIN! (in my book)... so best of luck!

DO NOT WASTE YOUR MONEY. They are so low you can hardly hear them. Just add $10 and buy Sony SRS-TP1. They sound MUCH BETTER, do not require any batteries, either, and are more portable.

I bought these speakers after the internal speakers on my laptop gave out. I use them for watching video or listening to streaming radio at my desk and they work fine for this purpose. The volume is sufficient for video/background music and the sound quality isn't bad. I wouldn't recommend them if you want to listen to loud/heavy bass music as the volume won't go that high and the bass is pretty lacking. Another consideration is the device that you plan to use them with - Because they are passive, you need a device that can power the speakers, so they will probably work better with a computer than a low-power mp3 player or something like that.

Ok, 2 Sony SRS-P7 Passive Speakers each 2.8 inches(w) x 4 inches(h) x 2.5 inches(d) $8.50 (amazon). I attempted to use these to increase the the volume on my G1 phone, however, my phone's tiny speaker was louder than these. I also tried on other devices (sansa mp3 player (no speaker on device, headphone jack only), zen mp3 player (headphone jack only), acer laptop) and still way to low. Even my acer laptop speakers (cheapest speakers on the planet, so I thought) were louder than these sony passive speakers. My conclusion is the sound of them is clear, but they are passive and without power they just have no volume. I did keep them as they could come in very handy with my mp3 players that have only a headphone jack to hear radio, etc. (especially in a power outage). Hope this helps others.

inexpensive, portable; sound like headphones, need to be up close to hear; nice and small, light weight; priced right; suitable for the price

I use these speakers mainly for listening to podcasts in bed or in the shower, and for these purposes, these are excellent speakers. For use in bed, I want something that will not consume power when the audio stops, since I may be asleep when that happens, and for the shower, I want speakers that do not use any external power, so that I don't risk electrocuting myself. As passive speakers that work the same way as earphones, these meet both of these requirements. But they are significantly louder than earphones. The hole you see below each speaker is a reflex duct, which uses airflow to increase the bass volume in small speakers, so that they sound like bigger speakers. I control the volume through my MP3 player, which, with rockbox installed, lets me specify precise decibel levels. At the top volume of 6db, I can easily hear what people are saying while I am taking a shower, though a hair dryer will still drown it out. At a volume of -14db, I can comfortably listen with the speakers by my pillow, and the sound hardly carries beyond my bedroom. The reflex ducts are great for the low to mid ranges, but it doesn't help the upper range. In these speakers, the upper range cuts off at 15,000Hz, well below the more typical 20,000Hz. While this makes them inadequate for most music, this range is just fine for podcasts, because speech is normally midrange. The cord is like an earphone cord. It consists of two cords, each one extending from the plug to one of the speakers. You may pull the cords apart to increase the distance between the speakers. Since the cord is one meter in length, you can get nearly two meters distance between the speakers by pulling the cords apart. I have chosen not to do this, because I mainly use them for monophonic podcasts, and I prefer the convenience of keeping the cord manageable. In fact, I have locked the speakers together at the bottom and use them as a single unit. With them locked together, I can easily stick them on a rack above my shower with the MP3 player stashed in an earphone pouch hung from a hook, and in bed I am more comfortable having them on my left side than my right.

I bought these for my desktop,in order to have a little bit of sound (not to watch DVDs or play games). Well, a little bit of sound is what I got! I have bought speakers at this price range before and these are the worst volume wise. They look lovely and are small enough to put in front of a monitor, but the volume leaves alot to be desired. If you want to watch programs on your PC or play games I do not recommend these.

What you get out of these speakers will depend very much on what you plug them into. I have plugged them into 3 devices with very good results, in terms of volume; and pretty darned adequate results, in terms of sound quality. I have used them with my Dell Inspiron 1420 laptop, my Creative Zen Vision:M MP3 player, and my Blackberry 8330 Curve, all of which are capable of providing enough signal to these speakers to be too loud for the typical office environment. I absolutely loved the improvement in the experience of these plugged into my laptop whilst watching a movie in bed, with the smallish speakers laying on either side of the lapdesk. For what they are intended to offer you, these are a good value, and seem to be well enough made to be fairly durable.
