Super sturdy, nice sound. So sad it's discontinued.

I really like these earbuds. I got 2 pairs, one for me and one for my partner. I had to get them somewhere else because when I wanted them Amazon was out of the black win the J4M (with mic) model.

 First, we could both find a comfortable fit with the included silicone tips. I had to try a few before finding the right ones but after I did they don't fall off. I'm a women and I don't find them to be so heavy as to feel uncomfortable. They are a little heavy compared to other earbuds, but not enough to bother me.

I wear mine often, almost every day. I'm not careful with them. Sometimes they fall to the floor or get caught in things, or I forget them in bed and get lost in the sheets. I'm impressed with the sturdiness of these. I've never had earbuds that lasted this long. I've had them for around 10 months, and they look the same as the day I got them, no signs of damage whatsoever. Also, the cable never tangles. I often throw them in my purse without the protective case that came with them and just pull them out and use them without any fussing around to untangle them or worrying that the cables will break.

As for the audio quality, I'm not an audiophile by any means but I find it acceptable. I don't notice that it sounds bad or anything and. It sounds balanced, and while the name says heavy bass I don't think it's so heavy it overpowers the other tones. The microphone is also of decent quality. I've used it for calls and haven't had any complaints. I asked around my family and they all said my voice was fine. I also used it to make audio note recordings on my phone with good results. It's not as great as a professional headset would be but usable.

The only con I can say about this is that it's discontinued. I like how the purple looks but these are not available with a mic anywhere so I settled for black. I emailed them and they used to make the purple in J4M but will not anymore since it's discontinued. The replacement (called bass earbuds) is dual colored which I don't like and also doesn't have a mic. It's disappointing that a great product like this is discontinued and I'm a little worried that I won't find it once mine eventually dies (it might take a while).

Yes I would recommend these to anyone.

I luv portable sound. I was looking for a sub-woofer ONLY unit but could not find one.  However, this unit has nice base and is very good. Flexible with inputs and charging. Great with an acoustic guitar on the back porch.

Update: Unit lasted two years with little use. Very disappointed. Has good sound but the amp started to shutdown and caused unit to constantly re-boot. Happened in all modes. I'm guessing the power supply/battery or amp failed.

Amazing sturdy well crafted product, too bad they are not supporting them any more.

At the time when I bought this, this was very nice and the sound was great but as technology evolved, this became obsolete.

This is my baby! We are inseperable. Too bad it was discontinued. Keep an eye out for them as they occasionaly pop up for sale. I would defenitely buy another one.

It's probably futile (or worse) to write a review of a 13-year-old portable audio device, especially one that causes profound embarrassment to my three children (all of whom are over 20 years old and all of whom have told me in no uncertain terms that I can never, ever, under any circumstances, tell anyone that I still listen to audio cassettes and am/fm radio).  But I recently purchased this device based on the two reviews posted on amazon.  I want to add a few words about it, even if the only people who read this review, if it ever is read, are likely to be humanoids opening an electronic time capsule 200 years from now.

First, in the interest of full disclosure, I did not buy this device on amazon.  I have no idea how it might have altered my view of it if I had done so, but I could not have afforded it at the very high prices at which amazon marketplace sellers are offering it.  I hope amazon won't kill my review for saying that, but it's important to share it.

Second, I love old technology and this is the best portable music device I have ever encountered.  It is literally a very high quality, very tiny boombox.  The two other reviewers have adequately sung its praises, and I simply wanted to indicate my enthusiastic agreement, as well as one further bit of information about its use as an analog fm radio.

There is no built-in fm antenna, which would ordinarily be a problem.  But as is so often the case, any conventional headphone set -- e.g., the wonderful Panasonic RP-HT21 Lightweight Headphones with XBS Port -- will instantly solve the problem because connecting headphones through the headphone jack does not disable the built-in speakers.

One last wistful word:  it looks like Panasonic has pretty much abandoned the lower end consumer electronics market, at least in the United States.  This is a huge loss, at least for me.  I have gotten enormous enjoyment from their wonderful portable audio devices for over 30 years. But nothing lasts forever and I'm sure that there are excellent business reasons for a great company to move almost exclusively into high-end markets such as large-screen TVs, etc.

But wait -- there are still those awesome and embarrassingly cheap Panasonic RP-HT21 headphones sold by amazon.  If you've missed out on Panasonic's last 50 years of portable audio greatness, you can still catch one of its  closing acts for the price of a cup of coffee.

Great sound to this day in 2016. It's a rotten shame Logitech switched the subwoofer to 6" for the Z906. It's the best part of the system.

I really really loved these till this happened at a gig last night ( see picture)
Don't let me discourage you. The 2.0 looks way smarter and better designed. I wish they they would let me trade in my old ones.

It deserves its reputation as a "giant killer." I have a stable of much more expensive headphones and earphone. Yet, the KSC75 is my go-to headphones. The sound is well-balanced, detailed, and immersive. Treble can be a little shrill sometimes, but there is an easy mod for that that the motivated, and handy, listener can try. I am neither motivated not handy, and have thus chosen to live with the stock sonic quality. It serves me well. You can't get better sound for this price, or for four times the price.

Ironically, the event that brought me to the review page is the failure of the left phone after 15 months of daily use. I don't know if it's the driver or the cable. Either way, it sputtered for a while last night and went completely dead this morning. I a saddened, but fifteen months for use for a pair of headphones that cost me $10 is enough. I took one star off for that from a review that would otherwise have been five stars all the way.

I don't believe in making a comment about a product until I've been able to use it for a while. With this item I just forgot to do a review after a while.  To bad it isn't available anymore, but if you run across it's worth the purchase.  I have been using it for a couple of years and find it a good replacement for my wired deck speakers.  Mainly just the fact that I can change what I'm listening to right there on the spot. With the deck speakers which were wired to my computer iTunes I would have to go into the house to change the playlist.  The sound quality is very good and the remote works fine.  The item is well built and solid it can take being knocked around, and I've used both batteries and plug-in options. If you have the option to use an outlet do so. I like the fact that the unit will recharge the iPod also. Very pleased with my purchase.

Did quite a bit of searching around and found this unit to have fantastic sound compared to many others.  The unit fills a room with thumping bass at high and low volumes.  As for portability, it is a little heavy; however, I don't mind as it really feels like you can take this unit anywhere without the worry of it breaking; it feels sturdy and rugged.  The unit is getting great reviews on the web and is priced exceptionally well compared to retailers in Canada so really this is a win/win.  You won't be disappointed in your purchase.

WOW ~ WOW ~ WOW ~ WOW!  These little ear bud safe so awesome!  Of all the earphones, buds, of any type that I have ever purchased, these have the best sound.  They have been discontinued however and are difficult to find.  After using them, I went back and purchased 3 more sets (at different times due to availability) as replacements.  If you get the, make sure they are the same product number though.  Many look alike.

I was a bit reluctant to get this guy, because my original Jambox stopped working shortly after the warranty ended.  It was a common problem where the bluetooth gets flaky unless a mini stereo plug is plugged *ALMOST* all the way in.  I contacted support and didn't have a good response, though I wasn't expecting much because it was out of warranty.  For something I paid $250 on, I was expecting more than 16 months of light use.

But I did love the old one, so I decided to give this one a try.

I'd say it sounds as good as the old one, though it's not QUITE as loud.  Maybe it has that mode turned on where it reduces the max volume slightly?  It is loud enough to work in the shower, which is one of the places I need the volume -- for when I'm traveling.

One thing I *LOVE* about this unit is that it finally has a "skip song" button, you press the button next to the volume buttons twice and it skips the song.  Three times and it skips back.

It seems a bit sturdier than the original.  In particular the grill, which I never had a problem on the old one but was always a bit afraid of bending it up.  This one feels super solid.

I'm quite happy with the sound from it.  If you like the "Bose sound", this probably isn't the box for you.  I found the Bose version sounded too "compressed" -- too much like radio.  Some people like it, but I find I get tired of it quickly.  The Jawbone I find sounds much more to my liking, I have a bit of audiophile history, and like my audio fairly neutral, to give you an idea.  If you want something that sounds clean, this is a good choice.  If you prefer something that sounds more dramatic, either use an equalizer app or get another brand of speakers.

Jambox in half the size?  What's not to like?

I've purchased about 8 or 10 sets of these over the last several years. I have spare pairs stashed in 2 cars, in my computer case and on a motorcycle. My kids have each grabbed pairs so I bought more. I lost a set while traveling in South America, and I think in Europe, and I have a pair at the office. I did have one pair break--the "control module" plastic pieces separated so I glued them back together with superglue. I love the volume control plus the answer/hangup button. Sound quality is subjective, so snooty audiophiles will always find fault with something if it's reasonably priced. My phone conversations and '60s to present day music collection sound great to me. :-)

My biggest fear with these is that Apple won't put a jack onto the next iPhone.

Wow I was really impressed with this amp, and would purchase again... But I think it has been replaced with a newer version. They're is an amazing amount of versatility all in an attractive package... With an excellent sound quality.

This item was discontinued. I bought it as a gift for my 9 year old. It is easy to use, packaged well, and comes with easy step by step instructions. The sound quality is excellent and very durable. The only thing I do like about it is it charges while plugged into your computer. I prefer a wall charger. Display is really nice and I like how you can use it for video player too.

I LOVE THESE HEADPHONES!!! I am super bummed they are discontinued. Does anyone know of a different headphone that has comparable sound and bass? These are the best headphones ever. and I am VERY picky because I listen to music at the gym. It drowns everything out. Very comfortable ear pads. The sound is amazing. I hope when the time comes that I need a new set of headphones that I can still find these somewhere.
