“Thats unfortunate. I've been using mine for about 2 and a half years daily, and the only problem I've had is the earpads deteriorated and I had to get replacements.”
“I love my M4 but sometimes when for instance indoors in a quiet room, I wish I could just use them without the processing stuff going on, which makes the listening experience worse.”
“I remember with the Momentum 4, the quality was really bad; when you used the microphone, it would lower the audio quality significantly due to bandwidth limitations”
“This is phenomenal well done bass is still emphasized but sound more clear, the mids have perfect pitch, the highs sound perfect and vocals are crisp well done”
“theya are absolutely fire, great build quality, amazing sound (if you play with eq, outa box they might be a lil strange) the app is dope, noise canceling powerful, controls amazing.”
“I'd advice not to, the 5's will be releasing soon, and the 4's, while sounding great, are the most PIA headphones I've ever used thanks to their BS touch controlls.”
“I still think it is an alazing headset to listen to music and very beautiful, but the cons are so annoying for this price that I cannot understand why they did not improve this.”
“I'd never get it again, though, and when these eventually go I'll be highly critical of future sennheiser options if they use the same app and have touch controls.”
“as long as you’re playing music on them you aren’t really hearing anything else so it is fine ig a small price to pay for a pretty big jump in sound quality.”
“i just couldn’t get used to the low end they produced. they were definitely more subby, but they lacked the punch i’ve gotten accustomed to from my xm4s lol.”
“If youre willing to sacrifice the ANC, I would 100% go for the m4s. I miss the sound quality on those so much, they just have more life and clarity in them. ANC is trash though.”
“They are great headphones expecially since they are now like €200. In my opinion the biggest con of the M4s is the ANC. But other than that they are great!”
“Then returned it all together. Litteraly not made for anything but the perfect temp in a ac cooled office. If the ac goes off the headphones are fucked”
“Its 5-band EQ is pretty useful and the low frequency is tighter on it than on most other Bluetooth headsets at this price range, if not all of them.”
“But all in all these have great sound quality, but I find myself reaching for the Bose when I travel as the case is more compact, and the noise canceling is actually noticeable.”
“the momentum 4s actually sound odd in some songs. They disappointed me because I thought the momentum 3 sounded as good or better than the AirPods max.”
“Sound quality is great and I have not had any problems with ANC yet. However, when I receive a phone call when my M4 paired to my phone, it gets all weird and the sound cuts in and off.”
“super good sound stage used it for light gaming and watching movies and all other multimedia. super great for calls,productivity and formal meetiSg and the ANC is decent (very good) doesn't have any issues whatsoever.”
“the ANC is shockingly bad for the price. Sennheiser have never quite got it and you can’t justify paying for them over Sony, Bose or Apple”
“The mids on the XM5 are terrible; it's really mushy and there's no clarity. Switching between them was truly a difference of night and day.”
“I love my momentum 4 and have them over a year but I live in a hot country and I find my self sweating a lot around the ear with them, even when sitting and only watching movies with them.”
“Io ho preso le momentum 4, non so se sono le migliori ma dal mio punto di vista sono fantastiche e la durata della batteria è ottima.”
“My left ear stopped getting sound after about 6 months. No drops or anything, just general use. I warrantied them and have had the new pair for a year now and they're fine.”
“Had to return mine just under a month (bought from Sennheiser website). Bluetooth kept dropping & left ear cup had a loud buzzing sound.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“There is a magnet embedded under the right earmuff side of the case. The headphones react ONLY when the right earmuff is placed over this magnet, as the left one does not have the sensor for it.”
“On PC, ny default the M4 tend to use the SPDIF output, and yes, this output has a hard limiter. Once I use the Analogic output, I can finally hurt my eardrums properly. That may be your case too ?”
“Going from the saved preset that’s still active in my SC app it should be something like this; 63Hz: -1dB 250Hz: +0.5dB 1000Hz: +1,5dB 4000Hz: +2dB 8000Hz:+ 1.2dB”
“Dude I literally had this problem yesterday! It may be a power glitch. Connect to a charger for 20s and then hold the power button for 10s (or more lol) and it should blink white! Hope it works for you”
“Never intentionally charged them. They charge automatically when I listen using the wired connection for lossless experience. So, can't say exactly. But they claim 60 hours, and heard about 90% accuracy from the reviews.”
“Momentum 4 wireless had this issue where microphone quality totally tanked when on Bluetooth. Redditors adviced to just disable the mic of the headphones in windows, or buy the adapter. Isn't the whole predicament just the codex ?”
“When I remove the headphones music or videos or calls pause which is great. When I take them off and I get an incoming call or decide to watch a quick video without headphones the ringer and any sound still goes to the headphones.”
“When you get it, first thing you’ll notice is that these are bass canons with slightly recessed mids. So I recommend using these settings on a third party app with parametric eq to fix this (sennheiser app doesn’t have one for this).”
“That's why I always put my m4's in the case as pad sides facing me (right ear cup on the left in case). That solves the issue.”
“No water resistance, but Ive worn them in light-medium rain with no issue since water droplets would only touch the top of the headphones’ shell and headband, so unable to get inside. I wouldnt risk wearing it while its pouring thoigh.”
“Ive seen teardown videos, its slightly difficult but still fully possible to replace battery on the Momentum 4's. Not sure if the battery's available on their website though, but you can get the exact same one for under 10$ on Aliexpress”
“USBC to USBC wired mode to device will allow highest quality audio if sent through. Need to be sending high quality though.”
“Are you sure you are using the Smart Control Plus app? They released this new version not long ago and are phasing out the old Smart Control app. There are many more features and it's one more modern looking than the Sony and Technics app imo..”
