Sennheiser MOMENTUM 4 Wireless Headphones, Bluetooth for Crystal-Clear Calls w/ Adaptive Noise Cancellation, 60h Battery Life, Customizable Sound & Lightweight Folding Design, Black

I have owned the Momentum 2’s for many years and love them. But, after the battery started to fail and took over 8hrs to charge I decided to upgrade. Here are my thoughts:Sound - Really good, but different to the 2’s. Took some time to get used to but I really like the sound now.Battery - Amazing. 60 hours is huge and makes such a difference not having to charge so regularly.Comfort - The 2’s were great but these are on another level. Can wear for hours on end without getting hot or ever feeling uncomfortable.Look - The 2’s looked amazing with the ivory colour. These look ok, but do not stand out. Build quality is excellent. No creaking on mine.Controls - I hate the touch controls and miss having a button to adjust the volume. If adjusting, then it is easy to activate a control. Changing the volume is hit and miss. I have turned touch controls off as they are too unreliable. It would be good to switch just some of the controls off and just have volume, or have the ability to change via the app. Maybe having less controls would help it work better.Connectivity - multiple devices works fine. I’ve had no issues but it niggles me that when you connect, you get a lovely voice that tells you it has connected, but when you connect a Bluetooth device, a lady from Essex tells you it is connected. It is so wierd they use different voices for different announcements.All in all a great pair of headphones but I wish Sennheiser would address some minor niggles.

I was going to return these then realised there was a problem with my bluetooth on a source.This was fixed and then I was given the full range of quality from these stunning headphones.The bluetooth connection is strong and holds on for dear life as you reach the edge of connectivity, then snaps back and continues playing when you wander back in range and for some reason?, you do not have to re-start a track as with some others.I am a dreadful audiophile and love my sounds to be available in top quality in all forms of reproduction.These do this soooooo well!, my old Sony xm3's are now in retirement.The Android app for these has allowed me to tune the sound profiles very well for different genre's ofmusic, as I like an eclectic mix from Infected mushroom via mellow jaz through to the most subtle of classical chamber music, to the full orchestral experience.We are are talking deep and wide soundstage here with great seperation of instruments and voices.Bonus feature time!,buy a decent wire for them and plug them in, they will then give your silly money wired headphones only ones a run for sound quality.10 out of 10.(ooh! they are comfy to wear for long periods too, clamping force just right)

At first I felt these headphones were a mixed bag of tricks. I had read other reviewers had problems but having an earlier Sennheiser model and being familiar with their app I hoped for the best. However it took ages to get going. The on off control is tricky - to get a bluetooth connection the on button must be pressed till the lights flash rapidly. It's also hard to tell if it's really switched off. I then had a nightmare trying to connect to the Sennheiser App. My older set connects to both the app and bluetooth in seconds and works brilliantly but the Momentum 4 took me the best part of an hour plus another thirty minutes to install a firmware update. The problem I had, I think, was I initially tried connecting using a Fire10 tablet and the App just didn't like it. As a last attempt I tried the Fire Max 11 which worked at once. I then then downloaded the update by which time I had had enough electronics for one very stressful evening. The next morning I tried again with the Fire 10 and all was well. It seems the update resolved issues connecting to the App but unless you have another device or can find another way to update it's frustrating. Sennheiser do say their App is designed for phones primarily and do offer support with tablet related problems but in the event I didn't need to contact them. Since that first attempt I have had absolutely no problems with connection at all on any of the three devices I use.The Sennheiser sound is superb on the Momentum 4. I very much like the Sound Check system which helps to establish your personal presets by offering several sets of three settings - you select your preferred out of each set. I like a wide range of music including jazz, opera, rock, metal and in a few minutes was able to save settings for each genre. I had done this before with my older Sennheiser with great success but the sound on this newer set is brilliant. Unlike other reviewers I like the app. Once you find your way round it it's easy to use and the online manual is comprehensive and clearly written.There is only one button on the Momentum 4 much to my relief - and as I have said that one needs a bit of learning to operate effectively. Other controls are by touch and these work extremely well - swipe up and down for volume, touch for stop start etc. Unless you are committed to buttons this is a great improvement. The set is extremely comfortable with a neat flat appearance. I have noticed no clicking or creaking noises and no heat to my ears. It stays connected even when I move around a lot and stops as soon as removed from the head. The case is well designed with room for cables and guidance notes.I have used the set for about 40 hours so far, battery is still 50% charged. Noise Cancellation is easy to adjust on the app or the headphone touch control and seems good although I am in a quiet room. I haven't tried a phone connection as I am in an area where mobile reception is appalling.Overall I am very happy but more comprehensive guidance notes in the initial paperwork would have saved me a frustrating hour - but I say that about anything new!!If your primary wish is great sound at a medium price this is a wonderful buy. But be ready to take time to establish connections and don't miss the update.
