Thrift Store Stereo: Philips AZ4000 MP3-CD Sound Machine Boom Box

I just hooked up our latest thrift store find. It's a Philips AZ4000 Sound Machine.  It's an interesting boom box from the 2001-2002 timeframe.  My wife was drawn to it and we bought it at a local Goodwill store for only $16.91.

Philips AZ4000 Sound Machine

 It has an electronically tuned FM stereo receiver and according to Amazon.com, the product also has the following:

• 20-track CD programming, repeat and shuffle play; firmware upgradeable
• 3-band equalizer and Ultrabass 2 bass boost enhance and customize system sound quality
• 2-way speakers with 4-inch woofers, dome tweeters, and bass-reflex cabinets
• Runs on 6 D batteries (not included) or AC power (cord supplied) 

Of course, this is a vintage boombox from 15 years ago.

Philips AZ4000 Dimensions

The unit itself has low and deep dimensions.  It stands about six-inches tall and is about 12-inches deep.  It's fairly heavy and the few available Amazon reviews characterized it as a bulky for a portable boombox. This unit is cosmetically challenged with some melted spots on the left-hand side of the unit.  (I think a previous owner may have set a hot curling iron or something on top of the little boom box.)

Philips Sound Quality

The sound quality is actually, truly, outstanding.  The unit got 4.5 stars our of 5 from Amazon reviewers back in the day.  It has 4 front-facing speakers and two rear-facing bass ports.  You can adjust the bass and the trouble by hitting the bass/treble button and adjusting the volume knob.  The changes you dial in show on the digital display.  Ultra Bass is activated by pushing the button.

The CD player is a top-loaded unit and should be able to read MP3 files from home made CDs.

Philips AZ4000 Drawbacks

I found the controls to be intuitive and easy to use.  Apparently, the Philips AZ4000 supports a remote control of some sort.  However, this thrift store unit didn't have a remote.  Fortunately, we don't seem to be missing any of the essential controls.  The worst feature of this unit is the lack of an auxiliary input.  While it does have an earphone jack, this vintage portable stereo precedes the Smartphone era and there is no way to hook up devices to this old school boom box.  That's too bad because the speakers are great.

With great quality sound, this $17 thrift store special Philips AZ4000 Sound Machine might be a great affordable alternative to an expensive Bose Wave Radio.  For under $20, you can't go too wrong.

A Modern Philips Boombox

You can still get Philips Boomboxes today in 2025. This one has an FM Radio, Bluetooth, and CD Player that can also handle MP3s on CD-R and CD-RW CDs.  You can find this nice little Philips boombox (below) on Amazon.

Dirt Cheap Audio Review: Insignia CD Boombox with AM/FM Radio

This compact radio / CD Player combination from Insignia is the go to sound system in my home office.  According to Best Buy, this is a CD Boombox with AM/FM Radio (Model NS-BBTCD01).  However, it is pretty slick for a boombox.  To me, it looks like a modern table-top radio.  The unit has Bluetooth connectivity, a USB input, and accepts an auxiliary input via a male-to-male 3.5mm AUX connection cable.  The CD player is a top mounted unit that you simply push to open and lay the CD in.  The radio antenna is retractable and easy to access.  Overall, the unit is sleek, provides decent sound, and is a budget-friendly alternative to a Bose radio.

The design of this Insignia product is a strong feature.  It looks like a modern piece of electronics and it fits in with sleek minimalist design principles.  It simply doesn't look like a boombox.  However, it has a carry handle that folds down into the body and is not noticeable for everyday use.  When I flip it over, I see that it has a battery bay for six C-size batteries.  As a "boombox," some Best Buy reviewers find it a little short on bass and boom.  It's really meant for use within a single room or office.  It does have pre-set equalization settings for Flat, Jazz, Pop, Classical, and Rock music.  A sound button on the left just below the bluetooth symbol cycles through them easily.

When considered as a conventional radio, the only drawback to this product is that it isn't designed as a full-fledged alarm clock.  There is no clock functionality.  The LCD display is bright when the unit is turned on and playing a CD and it seems like it would have been a no brainer to add a clock, alarm, and snooze button.

I bought this Insignia radio at a thrift store for about $20.  New, it is still available for $59 at BestBuy online.  Even at that price, I would consider it money well spent.  If you are looking for a nice simple radio and CD player for an older relative, I would also consider this to be a good choice. Another nice Bose alternative might be a bookshelf stereo system. They have been getting smaller and more compact. The Philips FX10 Bookshelf Stereo might be a good option.

As of 2025, the Philips FX10 Bookshelf is a best seller on Amazon. It has an FM Radio, Bluetooth connectivity, and a CD Player. You can find it here on Amazon.
