Logitech Harmony 650 Review


First, we are going to talk about the 650 that is an older model than the 665 as most people already know because of the numbers in the name. Although this remote support the Infrared connectivity and using this single remote a user can replace up to 8 different remotes at his/her house.

Instead of this Logitech Harmony 650 comes with the coloured Display that is used to manage devices or operate the activity easily. This LCD makes it easy to use the remote while at night and even though it also comes with the Backlit supports to find keys in the dark places.

This remote is quite impressive when it comes to the support of devices so this remote is compatible with around 225,000+ devices. Despite this, you can use it with around 5000+ different devices whether it is a Soundbar, Speakers, Satellites, Streaming Devices, or TVs.

Although if we talk about the pairing then the Harmony 650 offers IR learning feature and you can connect various devices using the code. Other than this it also supports the automatic pairing and you can even connect it with PC and use the Harmony software to connect devices easily.

The build quality of this remote is not good enough but it is still considered as Ok and that could last for 2 to 3 years. Although the buttons are quite smaller that could be hard to use especially at nights. This remote only supports the Infrared connection that makes it limited.

That means this cannot be used with the Smart Home devices neither with the Streaming Sticks. Because these supports Bluetooth or WiFi connectivity which this remote doesn’t offer. Additionally this remote is now discontinued by the manufacture and that’s why only a few products are left on the Amazon.


  • Harmony 665 is the budget-friendly universal remote control.
  • Works with almost 225,000+ devices and around 5000+ different brands.
  • It can be used to control 8 different devices at your Home.

Logitech Harmony 665 Review


Now let’s talk about our today’s second competitor that is known as the Logitech Harmony 665. This remote is quite awesome and no doubt this was released after the 650 then it comes with some improvement. Well! just like the old version this remote still supports the Infrared Technology.

That means there is no compatibility with the RF or WiFi/Bluetooth based devices. Despite this, the number of supported devices is increased from the 8 to the 10. Now Harmony 665 is being used to control a total of ten devices at your home but all of them should be IR enabled.

Additionally, this remote also comes with the Bright coloured screen that is used to manage your devices. Even though it also comes with the support of Backlit to find keys at night easily. But the problem is 665 also comes with the smaller buttons that could be hard to use even with the backlit.

Furthermore, many customers have suggested that the buttons located above are quite hard and require some force to make it work. This issue is faced by many customers and that makes it hard to use for elders or kids at your home and in this way, the lifespan of this remote reduces as well.

Other than this it also supports 5000+ different brands and has the compatibility of over 2,70,000+ deices including Satellites, Set-top boxes, Dish TV, Soundbars, Speakers and much more. The remote offers the automatic pairing feature that can be used to connect your devices instantly.

Even though you can use the Harmony Software on your machine to find and pair your devices much easier than before. But the problem is software isn’t as good as they say there could be mistakes while pairing. Overall the remote is made of good material is improved quite a lot than the old one.

Additionally, they changed the colour of the remotes as well because the 650 was only available in Grey while the 665 is only available in black. This is quite good for many people as they like the Black colour over the grey or they changed colour just to identify two different remotes because the design and functions are quite similar.


  • Logitech Harmony 665 is the latest model and they are still manufacturing it.
  • The number of supported devices is increased from 8 to 10.
  • It supports one-click activities to watch Movie, Sleep timer and so on.
  • Harmony 665 comes with the black colour that I personally love.
  • This remote also offers coloured display and backlit support to use at night.
  • The number of supported devices and brands are the same and will increase in future.
  • Automatic IR pairing makes it easy to pair with other remotes.
  • Harmony Software can be used to find and pair devices easily.
  • Works fine with Soundbars, Dish TV, & other IR enabled devices.
  • Just like other remote it also comes with the affordable price.


  • The buttons located above screen are quite hard to press and you need to force it.
  • Software is not good enough some devices need to be paired manually.
  • Consumes battery faster because of the coloured LCD.
  • No Android app is available to manage or operate devices.
