"Because they stay in my fucking ears, no matter what. ... They have stabiliser fins that mean running for a train, exercising, getting bumped in a crowd of people, or just walking at a normal pace doesn't come at the cost of an extremely expensive piece of tech just falling out of my ear."
"the only thing that stays in my tiny weirdly shaped ears."
"the fit perfectly"

"Sound: Sennheiser's Momentum lineup, Denon Perl Pros, Technics AZ80/AZ100, and B&W Pi8, in that order (taking into account Sound Personalization and AAT are being used)."
"Theyre somehow better than my big bose quietcomfort pair"

"Best of all, the earbuds have body temp and heart-rate sensors built in (NOTE - only records data if you use the Polar Flow fitness app)."
"Plus if you have the POLAR FLOW app on your phone you can track your heart rate and body temp with sensors on the earbuds."
"which have a heart rate and body temp sensor built in (ONLY works if you are using the Polar Flow app on your phone however)"

"Plus as an added bonus - they are "open back" which means the back of the plastic is not sealed shut like most earbuds - instead there is some air holes behind the speaker (technically called a "driver") on the earbud - this design helps reduce that annoying "thudding" sound you hear when jogging with other earbuds."
"I can hear everything around me"
"But they were specifically designed to reduce that "thud" noise you hear when jogging with normal earbuds"

"these sensors only record cardio data if using the "Polar Flow" fitness tracking app - something that most reviews don't make clear enough ... the data ONLY synced with the Polar Flow app, and was not accessible anywhere else! ... I was so disappointed in them"
"this data can only be recorded using the "Polar Flow" fitness tracker app (the data doesn't sync with any other apps). This was a disappointment for me."
"some sensors which reportedly don't actually provide accurate data (apparently the data doesn't match smart watch data)"

"for my average size ears they literally caused physical pain after an hour of use (to the point where I couldn't even tap the earbud to skip songs because it was applying more pressure to an already sore spot on my ears) ... they were essentially useless for me since I couldn't even enjoy an hour long bike ride wearing them"
"I REALLY wanted to like these earbuds but they seemed to cause me a bit of discomfort and some pain when wearing for an hour at a time so I ultimately returned mine. ... Wow yea after 30 minutes my ears were hurting from wearing them."
"they were uncomfortable for my ears ... they kinda really hurt my earbuds after 30 minutes of use ... my ears would hurt too much so I had to return them."

"Very reliably unreliable ... having two pairs replaced under warranty and still failed on the third."
"Mine broke down after half a year. ... First the left one started to sound weaker and then kaputt."
"right earbud gave out which I presume to be from sweat"

"Their biggest downside for you might be that they don’t have proper ANC! They only use passive isolation for that."
"the ANC works well enough, but not the best I've handled."

"my Momentum sport earbuds were a few notches lower in max volume than my Quietcomfort earbuds. ... I'd say the sennheiser sport earbuds were about "4 notches" lower on my phone's volume control compared to my Bose Quietcomfort2 earbuds."
"it was a bit lower max volume than my Bose QC2 earbuds"
