SENNHEISER In- Ear Audio Monitor, Clear, Wireless (509172)

Got these to monitor audio on my FX3 when filming mtb on trail. Much easier to use buds when I have a helmet on. Really like the fit and sound quality. Not super confident in the durability considering I’m constantly on and off with them during a gig. They don’t feel very robust but Sennheiser makes not of them being durable. Fingers crossed they last because I really like them.

The audio quality of these headphones are amazing. It sounds like martyrs in the room. When you have them properly seated, the only downfall is they have two big bulky control knobs, which I assume are the batteries.I find it easy just to tuck them in my hat. Overall these headphones are amazing

I was looking for a daily use earphone that is somewhat accurate as i am an audio engineer. These are a bit too thick sounding but I was able to modify the EQ to compensate. Overall great sounding.

The sound is pretty good and very comfortable to wear. The bluetooth distance is about 15 m without obstacles. I like the option to switch between bluetooth and wired. Very convenient

100% garbage. I am returning them as I write this. They don't fit and sound awful. I don't much care for TOZO, but they are 4x less the cost and 10x better in quality. This pair of Sennheiser in-ear monitors is indescribably bad. I've been had by Amazon before but I think this is straw.

Typical neutral Sennheiser sound. Great IEMs in terms of tonality. Bluetooth module needs a rework however. Sometimes it just doesn't want to connect. The range is terrible too. Sound will cut off when the phone is just 10 feet away.

Love them. Sound quality is fantastic. Fit in my ear and don’t fall out which for me is a big plus.

I replaced AKG N5005 with these for half the price, but seriously twice the sound quality. Actual bass and clear highs. I already know that i will get the IE 400s next.
