Source for battery replacement, Good Sound, Interface with remote very good, but not current

This is a recent update to my previous review.  Everything below still applies.  As others have mentioned the battery on the remote tends to be shortlived.  Mine "died" a few months ago.  Difficult to find replacement battery.  When I contacted the email address on the Chestnut Hill Sound website about the battery I got a response saying I could get a replacement battery if I sent a check to the provided PO Box for $49!!!  I found a place on Amazon that sells a compatible battery that appears like it should work (I haven't received it yet) for $19 including shipping. http://www.amazon.com/gp/product/B002MPZZGK/ref=oh_details_o00_s00_i00
Interesting product, if sound quality is a priority this is an Ipod player you should consider.  Sound is rich, full, detailed, maybe slightly slow in audiophile terms because of emphasis on upper bass and midrange.  But overall I think the sound quality is better than any Ipod player I've heard, including expensive ones like Bose, B&W.  Sound is pretty neutral and close to the music.  Feels more powerful than most and can really fill a small to medium sized room.  Very adjustable sound, including adjustable sub-woofer in the unit, and when adjusting the bass and treble you can choose the frequency that your adjustments kick in.
Most unique feature of George is the remote, which loads the titles of all the content on your Ipod.  You can search through and play any song, album, artist, or playlist and play it from the remote.  Only tradeoff is the graphics on the remote just include the title, no album art, it's not in color and feels about circa '05.  Also it's clear that this unit was designed for the original Ipods, not the "Touch" for example.  You can access all the features pretty much from the remote, as I said, but when docked on George your "Touch" itself will be controlled by George, and go into lock mode with it's display turned off.
Worth doing the software upgrade, makes search functions much more usable on the remote.
For it's original price $500-$550, no way, but now it's available for about half that, and I think well worth it.  I'm glad I got mine.  Includes AM/FM tuner and sophisticated alarm functions if you want to use it as a high end bedroom Ipod player and clock radio.

This thing is fantastic.  The battery life is so-so, but you get a good 8 hours or so of LOUD sound.  And the remote has a surprisingly good range.  Kinda wish there was a radio built in, but for the iPod, it's just what I was looking for.  The "surround sound" aspect is pretty dang sweet too.

Little bassy, but convenient and high quality. Use with rechargable batteries, was really the main feature i wanted. Lasts at least 8 hours of continuous playing.

Looks cool, rugged. Cord is odd length, hard to coil completely.

A usb and bluetooth would have been nice, but aux in is fine.

This is a reliable speaker and speakerphone.  It connected quickly and easily with every Bluetooth device I've tried, both in single user and Heist mode.  I haven't been able to disconnect a device from the speaker at any distance inside my house, even around corners.  It's fairly easy to use, with assorted informative tones and some spoken word information (for example, a spoken report of remaining battery life when it is turned on, or of the mode used when switching between indoor and outdoor mode.)

The battery charges quickly and lasts quite a while, which in my case is a very good thing because I've misplaced the proprietary charger.  While there is a USB-sized port on the back, it is covered by a rubber plug which does not seem to be removable.  Since so many other devices charge via USB, a USB port would make this easier to charge.

Sound quality from this speaker is not what I'd hoped for.  Midrange is clear and crisp, especially when sitting very near the speaker.  Bass response is a little weak.  The high end is a bit sharp and dry, and sometimes a little annoying.  It's mostly good enough, and if the speaker weren't in the $150 range I'd be very satisfied with with the sound quality.  While improved sound quality would probably increase the weight of the speaker, since it's only about 13.5 ounces I'd gladly take a few extra ounces for a fuller low end sound.

The speaker connects easily to multiple devices and remains connected at impressive distances, charges quickly and has very good battery life.  The proprietary charger is an inconvenience.  Sound quality is OK, and would probably be good for a lot of people.  I like it, but this is not my favorite speaker.

This was replacing a new unit I purchased that was faulty. The replacement was refurbished and the battery/charging was not very good. Could not connect to the website for upgrades. However, unit seems to work pretty well despite all this. I really wanted it for the FM transmitter that seems to have been discontinued on more recent models.

Like the header says, this piece has excellent sound, both for the user and the person on the other end of the call, but lack of life in the battery sucks. I have to carry a backup device to use when this one needs recharged. Improve the battery life, and I'll improve my rating!

sound bar works as advertised. remote on the other hand was DOA. battery tested fine and inserted correctly. remote dead.reported this problem to Sceptre and they sent me out a working remote very quickly. not only that, I also filled out my warranty papers with my problem and they sent me another working remote.
raise to a 4 star

Wonderful gizmo with a decent range. 1 remote battery was dead right out of the box but I still like them.

I've had this speaker for a while and I'm satisfied for the most part. The main reasons I bought this was because of the three inch drivers and replaceable batteries.

I've been into headphones and speakers for most of my life and larger drivers generally have a wider range. Most other bluetooth speakers less than $100 have tiny drivers in comparison. The sound is pretty good if you don't have unreasonable expectations, although the treble can get a bit sibilant at higher volumes (I have sensitive ears). There is a bass port on the back and I've found I get the best results placing this in front of a wall which allows the sound to bounce forward. I stated that the other reason I chose this over other speakers was because it uses regular AA batteries, here me out! Grab a set of 4 quality rechargeable batteries with this and you're set. Most other bluetooth speakers have a built-in battery which lasts between 5-10 hours and will degrade in play time in the long run. A set of batteries in the D100 will last you a while (manufacturer estimated at 25 hours). The throw-away batteries that came with these speakers lasted me almost three weeks of daily play time at medium to loud volumes. SUP?

The main reason I bought this was for when my friends play outdoor volleyball, BBQing, and any other outdoor activities. For my purposes the D100 is a great fit. Loud enough to be heard all the way across a volleyball field and the long lasting battery ensures that the music won't cut off in the middle of an intense match.

It's not all rainbows and cupcakes though. While it's well put together the materials used don't feel very durable. The mesh cloth that covers the drivers could be punctured at any time and the finish on the body has a few annoying scratches from when it was left in my friend's trunk. Also, the bluetooth connection quality could vary depending on what you're pairing it with. When connected with my ancient Cowon S9 mp3 player (bluetooth 2.0) the audio sounds really compressed, the connection cuts out, and the volume cannot be changed on the device. Using it with my phone (Optimus running android 4.1.2, bluetooth 3.0, son) I have none of those issues. Using a fairly current device and you should be fine. Another thing to consider is the size. It's definitely not as portable as a small Jambox.

Overall this speaker punches above its weight class and is a good purchase at a VERY reasonable price, highly recommended.

I've had a devil of a time finding a decent pair of headphones with a remote that's fully functional with Android. I guess these technically fill the requirements. The sound is awesome, with clear highs and decent bass as long as one of the sizes of ear pieces supplied fit your ears properly. (Unfortunately my huge ears don't fit that description, so I was forced to steal some from my old Sony set, which fit pretty much perfectly.)

The only downside is the remote. The Sony phones that this replaced have a sizeable set of flat-surfaced switches for the remote (maybe 1/6 of the circumference of the remote) which make them easy to find by feel. These? A set of very slender buttons (see the pictures) that lie almost flush with the curvature of the remote, and the little nubbin that marks the center mic/control button is so tiny you can barely feel it. After a few weeks, I've gotten used to fumbling around until I find it, but I'd say about 20% of the time I end up hitting a volume button when I'm trying to hit the mic.

The sound probably merits 4-5 stars, but the poorly-thought-out remote drags it down a star or so. I hear the second generation's remote was better, but also have heard they tend to slip out of your ears when active. Maybe the Pistons IV will have the remote from the II and the earpieces from the III.

I bought the RS160 to replace older analog Sennheisers, for which the proprietary batteries were at the end of life and difficult to replace. The sound quality from these new digital headphones is very good, noticeably better than from the previous ones. I also like the fact the RS160 uses regular rechargeable AAA batteries (easy to find). I would have preferred a better recharging base, as you need to plug in a connector to recharge, and a one-step activation when you want to use them (you have to turn on separately the headphones and the base, instead of just one button on the headset). However, these are minor drawbacks and, for the price ($123 and free shipping), I believe these headphones are very good and I would certainly recommend them.

Note to self...when the battery in your opener dies, after you replace the battery you have to reprogram it to the door opener (that didn't occur to my until I was standing in the garage programming these minis). In any case, I've got "lots" of door openers but I don't mind because these minis are just so convient. The range might be just a little less than a larger battery-powered opening (and certainly less than the HomeLink that is in one of my cars) but it's certainly adequate.

These sound great. The price is right, but the battery isn't lasting as I would hope. I have Sony BT50's which have lasted me over 6 years. They still work well and the battery is far superior. The Syllables only get I would estimate 4-5 hours of playback from a charge.

A little about my usage, I use them every night for 2-4 hours for watching videos and music after the wife has gone to sleep. I would like to get through 4 or 5 nights without having to recharge, but these will not do it. So for this they get 4 stars from me. Other than that the sound is great. They feel slightly flimsy, but not to the point of fragile.

They do have some form of noise cancellation but there is no way to turn it on or off. Others have questioned whether they do this or not but in between videos or songs you can hear white noise and notice a significant amount of exterior sound being cancelled out. Would like to be able to turn it off to maybe save some battery but no luck. Not a huge problem.

Good product - Lots of features but one AAA battery is not enough ... should have another AAA battery so that you can play back recordings with greater speaker volume (top volume of speaker is currently on the weak side)

Excellent sound. Battery easy to replace if needed. I have used the base unit for a year with the recent addition of this second set.  Build quality is solid, but the sound is what counts.

After a meager 2 years, the battery won't hold a charge for more than  20 minutes.  Naturally, I contacted Sena Customer Service at 2 years and 2 months. After 2 weeks of email exchanges, they told me it was out of warranty (which I already knew and stated so in my original email to them).  The best they could do is give me some battery information in an attempt to allow me to buy new batteries (it takes 2 different types), but they 'weren't allowed' to give me enough info so that I could actually find them online.

Even if the battery issue was resolved, I have to say that much of the User Interface and is in need of work. The buttons are hard to find with gloves. The jog dial is clunky to use for anything other than basic volume. No Push to Talk capability at all (greatly desired when riding in a group and using the bike to bike feature).

The net after 2 years is this thing is just not worth the money IMHO.  I spoke to a few dealers about some of my issues. By an large they all agree that the reliability of Sena devices isn't as good as other vendors. Certainly a 2 year shelf life is pretty awful for a device costing this much.

Original post

So far works very well. Have used it with both a phone (Samsung Galaxy S5) for music and telecommunications and a nav system. For nav, I'd used both a Garmin Zumo and a tablet (Samsung Galaxy Tab S2) running Copilot. The phone and Zumo paired right away. I did need to watch t he YouTube video to get the tablet to pair as a 2nd phone. But once I watched it, it was very easy.

Not a big fan of the speakers. I use and recommend good isolation ear buds instead. It is great that this unit is already set up for them. They'll actually protect you hearing. If not, use earplugs, but if you do, the speakers really aren't likely to sound very good. They aren't that great without earplugs.

The ambient mode is a great feature, but as others have reported, it could use some tuning. I find the button on the bottom that's used t I enable it is hard to find with gloves.

Bluetooth sound quality is very good. I haven't tried bike to bike yet, but looking forward to hopefully no longer needing a two way radio. Not have I tried the FM radio.

I expected wind noise but I really don t notice it.

4 1/2 stars

This player has great sound and very intuitive controls.  The earbuds have a soft cover that is very comfortable and helps them stay in the ear well and not fall out. The case that comes with the unit is cheap; it has a strap that holds the arm band, but is thin clear vinyl.  The optional protective case is made of a thick spongy plastic that protects the unit well from drops.  It has a plastic belt clip and a strap for the armband.

On the down side, I didn't notice in the specs that the unit is not rechargeable.  It uses a AAA battery.  Had I noticed that, I might not have bought it.  That said, the battery seems to last a long time.  This player is much bulkier than my last player, being 3 inches long and almost 7/8 inch thick.  I work out with the unit in my shirt pocket, so it's noticeable.  On the other hand, my wife uses the belt clip with hers, so it's not a problem for her.  The other negative is that when I switch from music to FM radio and back again, the player begins playing at the start of the playlist instead of where it left off.  That's the most annoying feature of the player.
