ZS-RS60BT 06 April 2019 by Jkins (USA)
Unit sounds fine and it is a nice stereo for the price. Just one complaint: I have to use a flashlight to read the display at all times, day or night. How much effort and cost would it have taken to add a small LED so the display could be seen. What a hassle and inconvenience.

ZSRS60BT 24 December 2020 by Rob3 (USA) Verified Purchaser Verified
I needed a CD player with blue tooth hookup, so this fits the bill. The cd works fine, the sound is good but the annoying part for me is the display is dark and should be illuminated. There's a light to show the power is on but there's no light for the display. I'd also like to have some control over the sound, just having a mega bass isn't good enough. Bottom line...it's a good enough boombox but I'm not going to brag about it.

The feature I love most about this model is the Bluetooth capability. It is great for streaming music, news and sports and with the CD Player, if you are like me, you can play your CDs. It has one great feature as well, if you have music in a digital form but want to put it in a hardcopy form, you can transfer digital files onto a CD.

ZSRS60BT 03 December 2020 (USA) Verified Purchaser Verified
The CD player quit working after 4-5 weeks. I had ordered online from BestBuy & they told me mfg would cover repair or replacement. Took much effort & frustration & several months before could reach anyone at Sony. Then they required an invoice which I never had. I had my online order dated & priced & the chg on my credit card but Sony wouldn't accept that! I've given up. Won't deal with Sony again.

ZSRS60BT 18 November 2020 by mellen (USA) Verified Purchaser Verified
This Sony CD boombox with Bluetooth is a piece of you know what! I bought it in July 2020 to play my CDs, and it worked fine for about 3 months. Now, for some reason, it won't read my CDs. I followed all the mfg instructions in an attempt to resolve this issue, but it still won't read my CDs. Sony USED to be a company that delivered quality products. So what happened?

Playback experience not good...
ZS-RS60BT//CSP5 02 September 2020 by Rcemine (Singapore) Verified Purchaser Verified
I bought this on August 12. About 2 weeks after I noticed it would start making noise like as if the laser was struggling to read the CD especially when it reaches the 3rd or 4th track. It would happen even if the CD is new and has no scratches. Have to stop the playback, reset the CD and play the CD over again. Sometimes it would play the CD with no issue then randomly the issue would happen. It just ruins the listening experience.

ZSRS60BT 26 August 2020 by xgreaser (USA) Verified Purchaser Verified
I just bought this yesterday so this is a out of the box review. I will say the sound quality is very good and the reception is Good for FM and Poor for AM which is a shame because I listen to a lot of AM. Next right out of the box` the power cord was defective it was very loose fit on the radio and would fall off if moved, with luck the cord from the Sony this is replacing fit nice and tight. My other problem with it is I put on a CD when I go to bed and if I wake during the night which I usually do I'll play it again. There is no way I can do that with this unit without turning on the light and putting on my glasses as the buttons are hard to see in daylight and impossible at night. Once I'm sure I'll be keeping it I'll glue something onto the buttons so I can feel them, but a button on top you could press to illuminate the other buttons would be nice. Other than that it's a nice radio.

I bought this 2 months ago as a gift for my dad. It worked great initially and he was thrilled to have something to play all his CD's on- after just 2 months it quit reading the CD's. Very disappointed in this product. It was nice while it lasted just 2 short months!
The sound is so superior!
ZSRS60BT 19 June 2020 by Patrick31st (USA) Verified Purchaser Verified
The sound is so clear and so superior to other units I've owned. There is no static or interference and I am very happy with the LCD display for precise tuning to the stations I want. It has many features I have not used yet, but already I can tell it is just a superior product. I am very happy with it and would recommend this unit to anyone wanting a superior product.

Light, Compact and packs a punch!
ZS-RS60BT//CSP5 28 May 2020 by Telepgm (Singapore) Verified Purchaser Verified
I bought this Sony Boombox because of various reasons, most sentimental. I grew up with Sony: a symbol of reliability, awesome design and intelligent innovation. When I saw this on a good deal from one of the official distributors, I bought it in a heart beat. The boom box is light weight, compact and packed with all the functions which a modern boom box should have. Especially the Blue Tooth function, which is extremely relevant in current times for Spotify, Netflix etc. The volume of the Boombox is at level 30 (digital display) which is not especially loud, but it's loud enough for a living room and for a small party.

Pleased with boombox because of the bluetooth and CD to USB conversion. Output from Audio-Out is fantastic on headphones as well as to an amplifier. Lightweight and very portable even with batteries. Megabass is not superb understandably from the size of the speakers. Hope it is as reliable as my 15 years old AIWA.

ZSRS60BT 11 July 2019 by Radachek (USA) Verified Purchaser Verified
Just started using it. FM receiver sensitivity is average and requires a good strong signal. With the external power cord in use, batteries do not work when power goes off, you have to remove power cord from unit. 1st thing used is the CD to USB record feature. Really like the CD is securely held in place.Power does not turn off with power cord, just displays STANDBY. Sound quality is average for a small thing like this so I will connect to external amplified speakers. Love the portability with battery power.

ZS-RS60BT 13 June 2019 by Deb54 (USA)
The unit serves the purpose for which I bought it, but it is always on "standby". I cannot get the unit to turn off. The on standby display is always lit up. Apparently it is always on? It does not power down when I press the power button. Is this correct? Is unplugging the unit the only way to power it off? Nothing in the manual addresses the standby mode.

I received this as a gift to use at work, I am disappointed at the sound quality. The volume is just loud enough to hear if I'm standing near the radio. The "Maxx Bass" button slightly increases the bass. The antenna broke within a month of use and a replacement from Amazon is half the price of the radio! The good side is all the features it has.

The sound is very good using all audio options. I like having the CD, Bluetooth, Radio, and other Input options for audio. The physical unit is not too big, nice for the sound produced. Programmable Radio Station ability is nice too. I prefer Sony products, have for years. So far this product continues the tradition.

More than just obsolete...
ZS-RS60BT 03 March 2019 by Myles88 (USA)
1) It does not record as the classic circular button labeled "REC" implies... it doesn't record from Bluetooth, the built-in radio, or even the audio input. It merely copies the CD contents to the USB device (my Android Nougat is not compatible, period). 2) It is very inconvenient. After spending an hour renaming songs on my USB device to play in order, they played back randomly. They were also very slow to load (which, for my solid state USB devices, is very ironic). It can only have 3 preset radio stations. It also has no alarm clock, remote, or backlight. For this boombox to have Braille would have been acceptable. Most of the information about this boombox is underneath, with nothing to hold the boombox sturdy while reading it. 3) It is not power efficient. For a modern , expensive boombox that requires 6 C batteries, I'm rather disappointed that this doesn't have anything along the lines of CD changing, optical input/output, creating CDs, playback (at least) of SACDs, DVD audio, or an interface to act as a CD drive/audio input for your computer. Worse, the power input is very fragile. Just a small wiggle of the cord can shut it off.

Bought this because of the good reviews. A few months ago, my wife told me that she can't play CDs any more. It plays for about 20 secs then just stops. If you skip to next track during that time, it plays THAT track for 20 sec and stops. I was looking for another for her for Christmas and noticed that it's less than a year old. How long is the warranty? I know it's a budget boombox, but all we want is for it to play CDs. For more than a year. Sony? What's up?
