I had recently lost my Sennheiser CX 3.00 in-ear headphones and went to replace them, I was informed of this new series that had “replaced” the CX 3.00 with superior sound quality. After a month of using these, and much discomfort, I found my old headphones which had been washed and found in one of my sweatshirt pockets. I then did a comprehensive comparison between the two pairs, and can certainly say that the comfort is much better on my old pair, but the sound quality is practically impossible to tell the difference in my view. Given their significant difference in price, I'd recommend avoiding this pair. If they were of similar comfort and from the buyer's point of view there are noticeable sound differences, then I would recommend you consider this pair.

First off, I like the way these headphones look. They're classy but not flashy. It has a nice headband stitching and a nice consistent design. The headband has a metal piece that runs all the way through. It has a decent enough clamp to stay on your head but doesn't create too much pressure.

Like a few others, I was worried I had just dropped way too much money on a pair of earbuds of all things! I mean, I already had a pair of old ones, but they were just run of the mill in comparison. The sound from these is just so full and immersive. Give them some time to burn in and warm up, and wow, you will be blown away. I can compare these to the quality of my Audio Technica m40×'s. Next stop, wireless!

I just love this product and not forgetting Goodguys had amazing customer service! 5 stars

The depth and breadth of the sound field produced by these earbuds is incredible -- definitely the best earbuds I've ever tried. The free sennheiser app -- also allows you to customize and fine tune the equalization a bit to your liking. Would agree with other reviewers re: volume.

Comfort and fit Outstanding sound quality Connectivity EQ customization through app

volume control and track selection a bit tricky

Paired these with a Creative Labs Sound Blaster E5 portable headphone DAC and amplifier. Only wired headphones can be used with the E5 (it can source music via Bluetooth). I use them when driving an open top car and find them to be excellent for hours on end with a sound quality that would be hard...

Excellent sound quality. Silky, rich sound with deep bass. The only thing I'd say is I'd wish they'd go louder. The touch controls are impressive but difficult to start with. Battery life is good and the carry case charges them in between use.

The best true wireless buds you can get, fantastic sound, great fit they won't come loose and have three sizes of ear caps so you get a proper fit. Amazing sound and the app has various sound preferences. Connects automatically with my IPhone, and holds the connection really well.

The wireless, Momentum Free headphones from Sennheiser aim to offer a little luxury in terms of equipment and haptics, which means a leather case for transport, sound channels made of stainless steel for optics and good sound for the ears. Let's see if everything fits together.

While $300 is a lot to spend, you get a lot for it. Among true wireless earbuds, it's tough to top the sound quality, controls, and fit of the Sennheiser Momentum True Wireless.

Great sound quality; Solid connection

Price; No foam tips; Isolation
