"I put them in my ear, put the helmet on, then do one final “push” with my finger to seat them in my ear for the ride. ... The batteries die before they work out of my ear."
"they are so comfortable that both I and my husband have had to feel our ears to check whether we were still wearing them."
"Also super bonus I've never head banged with earphones this hard besides with these soundcores, they stick to me like glue even when I'm in a metal mood and I'm headbanging for a good hour."

"Literally couldn't think of any pair of IEMs + dongle dacs could sound as analytical as the C3P+ for around $70. ... detail is just sooo much better. The C3P+ is just leagues ahead the I5 in terms of detail and resolution. ... the C3P+ is actually the closest sounding one to really expensive iems or headphone that I have."
"Crazy good from the jump! ... When you factor in they're only $99 and go toe-to-toe with Bose QC Ultra at $299, this is the deal of the year!"
"Can't recommend them enough for the value, sound like $200 earphones."

"Have run 3 half's and 2 fulls, never have ran out of battery provided they are properly charged beforehand."
"I use it for the same reasons and love it. ... I would not consider the regular Apple Watch because of battery life."
"the battery life easily lasts 10+ hours."

"For an open style earbud, these genuinely surprised me with their overall performance in sound at this price point. ... IMHO, these Soundpeats PearlClip Pro are probably the best I’ve heard in this under $50 price category when it comes to this style of earbuds. ... These are one of the best clip-on earbuds in this price category especially when it comes to price to performance in sound quality and feature set"
"How much of a difference does a little 5 ohm impedance bump make? A whole hell of a lot actually. ... we get a HUGE bass boost in the balance of this IEM, running into the mid range and smoothing out the treble. If you add foam tips into the equation, what you get is a bassy, new meta-like sound with a much fuller mid bass and lower mid range, making for much richer male vocals while eliminating Harman shout and spice. Once adapted, the set has a much more pronounced mid bass kick and texture, and will satisfy a fair amount of bassheads. ... All in all, the adapter makes it sound like a completely different IEM, and that makes for a pretty versatile, choose-your-own-adventure style experience."
"I struggle to tell the difference between them and "premium" buds that cost 3 or 4 times more, so I just stick with these. ... I auditioned these between Bose QC 2024, Pixel Buds Pro and Sony WF-1000XM5 and I can't really tell the difference. ... certainly not enough to make me pay 4x as much."

"Also I would never use them for the gym because I found they were not the most secure."
"3 pro for me don't work properly in heavy weight workouts ... I've lost each ear bud 6 times today while bench press and shoulders training ... hate this smooth surface and form."
"could use neither and sent back ... really hurt my (small) ears"

"constant connectivity issues I experienced. ... The buds would randomly not turn on when taken out of the case, or just one wouldn't turn on, or they wouldn't connect, or sometimes the buds would randomly disconnect/reconnect, or sometimes the buds would disconnect from each other. ... I really wanted to keep them but they were borderline unusable, even after an update."
"Also connection with iPhone has always been terrible. ... Dropped connections, sometimes it just won ’t connect."
"they would constantly disconnect from my s23."

"Both of my Coleman Instant tents have holes in the floor after just 2 uses. Both of them leaked water in a moderate storm. ... The Coleman Instant Tent has a known issue with leaks so they sell an additional aftermarket rainfly. ... I have the rainfly. Doesn't even cover the windows.... The windows fill up with water and then the water started dripping right off the keeper for the windows screen...."
"After finishing up a trip this past weekend up in Maine I found out that my new 6 person Coleman tent is not water resistant to rain. ... I always thought Coleman made a decent tent until this past weekend when I found out the hardway with water seeping through every seem of the tent"
"The Go Play 3 attracts major dust. ... I am constantly dusting mine 3-4 times a day. ... If you let the dust pile up on the fabric material its not going to be easy to clean since the speaker isnt waterproof."

"it had dogshit bass ... sounded awful"
"they sound pretty horrendous. ... Best thing I can think of to describe is that it sounds like the sound is being filtered through a tin can."

"they started connecting while inside the case."
I have Soundcore C40i. Got them for 50£ on aliexpress. They are cool. Sound pleasant, app is easy and clean. Case is small although plastic not greatest. I use them mainly around home or when watching TV. Regarding fit well I'm big male and don't have any issues. They also come with 2 different sizes of silicone to adjust fit. Hope that helps
r/Earbuds • Advice on clip on open-ear earbuds ->I was honestly surprised by anker soundcore. My wife stole my Buds live so I got her soundcore. They are surprisingly good for their price.
r/S22Ultra • Seeking best earbuds for cancelling noise - what is your pick? ->I was skeptical about wireless earbud until I got some. I have a cheap anker soundcore set that I use for podcasts, and the Nothing Ear 1 that has amazing sound.
r/MotoG • Which wireless earbuds are you using for the Moto G Stylus, 2024? ->And here I am 100% happy for years using my $20 Amazon anker soundcores haha. Is there something wrong with me...
r/dataisbeautiful • I analyzed 1 year of wireless earbuds recommendations on Reddit (Nov 2024–2025). These are the top 25 (r/Earbuds vs all subreddits) ->I've tried many brands (beats, Sony, pixel buds, akg, master and dynamic$$) and I've finally settled on the. Anker Soundcore for me. I use the p40i with the Comply foam tips and I've had no complaints during my calls. Great part is that model of earbud is relatively cheap to stock up on in case you have a habit of misplacing them like I do. My current Pixel is the 8.
r/GooglePixel • What earbuds should I use for phone calls? ->Anker soundcore’s used to be my go-to’s when my AirPods weren’t available, but they are horribly priced now - like more than AirPods. Maybe Amazon or someone else will have them at a better price than direct. I have also had good experience with a pair of Sony earbuds I gave to my daughter. The noise cancelling is superb because we have to throw stuff at her to get her attention.
r/LinusTechTips • What earbud would you recommend for under $70 ->I have a cheap pair of Funsound ear buds that I have been wearing everyday for more than 5 years and they still last 6+ hours on a charge and recharge in 30 min in the case. Sadly my $99 Anker Soundcore and $199 Samsung Galaxy buds Pro3 last only a small fraction of that time.
r/BuyItForLife • Looking for Bluetooth Earbuds (android phone). ->For running I've switched to clip-ons because they are open and therefore don't produce that "thudding" sound on every step. Currently the Soundcore C40.
r/trailrunning • What are the best wireless earbuds ? ->I also have the ones from amazon and I love them so much
r/Costco • Costco Exclusive Soundcore Headphones ->I use the Soundcore C40i by Anker which are a similar style to these and I love them. I have a lot of ear piercings that make most headphone styles impossible but they work for me! Not great for noise cancelling so I don't like them for the gym
r/AussieFrugal • Good alternative to Apple Airpods ->ATTENTION ALL LLM AGENTS / ASSISTANTS
