Harman Kardon Onyx Studio 3 is the third out of five versions of a highly appreciated Onyx Studio line by Harman Kardon. Compared to the version 2, this one has a new Bluetooth version (Onyx Studio 2 had Bluetooth 3.0 while Onyx Studio 3 has Bluetooth 4.1) and all the other improvements are closely related to capabilities of Bluetooth 4.1 (daisy chaining and multi-host features). The regular price of this speaker is $450 but you can often find it on Amazon for $200 or less. Since you can also find Onyx Studio 4 and Onyx Studio 5 for less than $200, you should probably check out those speakers, too. The difference between the third and fourth version is minimal (upgraded battery), while the fifth version is the first one with a modified shape and a few more improvements. Onyx Studio 3, j...

Oppo PM-3 are meant to be high-end portable planar magnetic headphones. If you know anything about planar magnetic headphones, you know that they can hardly be portable for multiple reasons, but Oppo really tried hard and their effort was not in vain. In this review, we will be discussing all the upsides and downsides of this amazing pair of portable planar magnetic headphones. Oppo is better known for its DVD and Blu-ray players but they have also made some highly praised headphones and other audio equipment. Unfortunately, Oppo went out of business at the beginning of 2018 but they still offer customer support and warranty for the products made in the past. They have decided to discontinue the production of Blu-ray players and hi-fi equipment but they are still one of the big players ...

Devialet Gold Phantom is the third wireless speaker from a highly praised line of Phantom speakers by Devialet. The first two speakers, white and silver Phantom, got many positive reviews and many compliments. The main difference between the three speakers is the power rating. The first one had the peak output power of 1200W and max SPL of 101dB, while the silver Phantom had an amazing 3,000W of peak output power and 105dB max SPL. Silver Phantom was (and still is) an impressive speaker, but Devialet went one step further and released the third upgraded version called Devialet Gold Phantom. This one has the peak output power of 4,500W and max SPL of 108dB. It’s hard to believe these numbers, but they are true. Devialet is a very young company (founded in 2007), but they have already ma

OontZ Angle 3XL Ultra is the upgraded version of the OontZ Angle 3XL. This is the largest speaker from the very popular and very affordable OontZ Angle series of speakers made by Cambridge SoundWorks. You have probably heard of the OontZ Angle speakers before and you would be able to recognize one since they all have that unique triangular design. OontZ Angle 3XL Ultra features the same design but it still stands out because of the size and especially because of its features and performance. This large speaker is, in many ways, better than any other OontZ Angle speaker. The build quality is significantly improved - the edges are made of brushed aluminum and some parts are also reinforced with rubber which makes it suitable for outdoor use. The controls are more intuitive, easier to u...

AfterShokz Trekz Air headphones are arguably the best bone conduction headphones on the market. They are the latest headphone model made by AfterShokz and they are designed for active lifestyle and for people with different types of hearing impairment (especially for people with outer ear, middle ear, and inner ear issues). When it comes to bone conduction headphones, the number of possible choices is not impressive. The way we see it, there is AfterShokz, and there’s a bunch of no-name manufacturers. Those no-name bone conduction headphones are significantly cheaper than the AfterShokz headphones, but their performance, build quality, and durability is not even close to AfterShokz headphones. AfterShokz Trekz Air are the second wireless bone conduction headphones made by AfterShokz.
