Sennheiser CX 150BT Bluetooth 5.0 Wireless Headphone - 10-Hour Battery Life, USB-C Fast Charging, Two Device Connectivity - Black (CX 150BT Black)

Sound quality is better good considering it's a wireless headphone, functions work well, bluetooth function is great. They are a little difficult to fit for my ears.

I use these on my bike rides and it works well with a long battery life

Amazing quality and battery life. Strong connection that I haven't had much trouble with. Because there are two bulky parts, the balance is mostly rear-weighted which makes the buds sometimes fall our. Other than that, great product!!

To understand where I'm coming from, I do not need these to be amazing earbuds in the way of audio. I needed earbuds that stay in my ears while I'm riding the train, or walking around. That being said, I always prefer better audio than worse audio. I don't have any complaints about the audio. The last time I have used similar earbuds was over four years ago with the Jaybird X2. Personally, I don't feel like this technology has improved much since then.Compared my memories of the Jaybird X2 from over four years ago, I have several big complaints in terms of usability:1. The bit in the middle. The heaviest part of these earbuds comes in the very middle of the wires. This guarantees that this thing will be weighted straight downwards between your ears. This makes it so that whenever you move your head, this thing will move around like a pendulum going everywhere. Also it moves uncomfortably behind your neck if you do decide to move it around your neck.2. The wires are too short to wrap around your neck, or have any way to keep the said bit in the middle from going everywhere. I would prefer if I could do so such that even if one of the earbuds fell out, it wouldn't swing into oblivion with nothing preventing it from falling out other than a single other earbud stuck in my other ear.3. A lack of a provided clip to keep it out of the way to dangle. Even if there was a clip, between the shortness of the wire, the dangly middle bit, and the volume control part, there wouldn't be a very good place to clip anything.4. I suppose this is specific to switching from the Jaybird, but the fins used to really help keep the things in my ear.My conclusion: It sounds fine, but there are enough small quirks that annoy me enough to wish I bought something else.

SOUND QUALITY IS FINE, COMFORT IS FINE, BATTERY LIFE IS LESS THAN 10 HOURS, BOTH UNITS FAILED. FIRST UNIT FAILED IN A MONTH WITH "RUSHING" SOUND IN ONE EAR PIECE. THE REPLACEMENT UNIT FAILED IN A SEEK WITH A SUDDEN "SHUT DOWN" NOTICE. AT THAT POINT IT WOULD NOT POWER UP. IT ALSO WOULD NOT CHARGE. TWO IN A ROW IS A BAD SIGN.AMAZON HANDLED THE FIRST REPLACEMENT AND THE NEXT REFUND PERFECTLY.

I have found these earbuds to be the most comfortable, reliable, and longest lasting regarding battery life than others I have tried. They last well over four hours of constan. I don’t use them longer than that in one sitting so I can’t say if they would last 8 to 9 hours.

The ratings I give for this can be misleading to those who do not understand. The sound quality for these buds is great! But the comfort of dealing with the tiny size is frustrating. My hands are not large by any means, I wear a medium men’s glove as large do not fit comfortably to me. Anyway, the other thing about these buds is the battery and cord. The battery is encased in a smooth plastic, in-line capsule that weighs the cord and earbuds down and there’s nothing to keep it on your person except the foam pads for the ear openings, which they do a remarkable job of and four sizes are provided. I’ll keep these for now until I find a good replacement that combines all I am looking for without independent and completely wireless buds that are easily lost and do not provide great sound quality

What I like: Sound is excellent. Easy to pair with two devices. Great range on the Blue tooth connection.What I don't like: Control buttons are small and the shapes on them are hard to feel. The microphone picks all noise around you. The position is low enough that my collar rubs against it. The person on the other end can barely hear me over the back ground noise. In a quiet room these are great, but in my truck they are worse than just using the spearker phone.

Da ich leider meine Sennheiser CX 6.00 BT verloren habe, hab ich mich ohne große Erwartung für diese In-Ear Kopfhörer entschieden. Ich komme sehr gut mit Kopfhörern klar, mit dem richtigen Aufsatz bleiben sie auch bei mir im Ohr. Der Klang ist für mich auch gut u es sieht so aus, als daß die Laufzeit auch länger ist. Ich finde der Kopfhörer ist technisch/optisch gut ausbalanciert.Ich ziehe einen Stern nur deswegen ab, weil mir trotz allem meine CX 6.00 BT an der ein oder anderen Stelle halt doch besser gefallen haben.

Ich benutze den Kopfhörer in erster Linie, um beim Sport Podcasts o.ä. zu hören. Musik höre ich darüber nur selten. Für mich steht im Vordergrund, dass das Gerät unproblematisch funktioniert und bequem ist. Beides trifft auf diese Kopfhörer zu. Was hat mir nicht gefallen? Die Gummiabdeckung über der Ladebuchse lässt sich nicht mehr schließen und die Haltbarkeit lässt zu Wünschen übrig. Die Kopfhörer haben nur etwas über ein Jahr durchgehalten, jetzt gibt die rechte Seite keinen Ton mehr von sich. Schade, daher nur drei Sterne.

I bought because I have small ear canals and these offer an extra small ear piece. It fits well, but they don’t stay in the ears when sweating while running. The sound is good, but not enough bass for my liking. I do appreciate the longer battery life, which is another reason I chose these.

Suenan increibles al ser sennheiser, lo malo es el diseño, el peso que ejerce el receptor los vuelve incomodos , no está balanceado ni es ergonomico para ajustarse al cuello, lo que provoca que se caigan o se atoren con la ropa

Product: SENNHEISER CX 150BTPurchase date: Nov 26 2021I have been having issues with constantly losing in-ear buds; they are small and can be easily misplaced. These in-ear headphones has an "idiot" string linking the 2 ear buds together. When not in use, the headphones can rest on the neck. Perfecto.Pro:* Bluetooth 5.0 has great range. I have transveresed 3 stories and the connection to my phone is strong with no "wobbling" of sound or microphone when chatting on the phone or listening to music.* 10 hour advertised in-use battery life mirrors actual performance.* 1.5 hour advertised charge time mirrors actual performance; this is realatively quick compared to competitor's product in similar class that usually takes 2.5 to 3 hours.* 340 hour stand by time which is excellent. Competitor's product in similar class typically has 200 hour stand by time.* Multi-product connection works flawlessly.* Earphones are very light weight and stays in the ear effortlessly for hours with no pain.* In-line volume and device control works very well on an android based phone and windows 10 computer.* Microphone works very well when using the phone or internet based meeting applications. Sound is clear with limited sensitivity to paper rustling or keyboarding noise.Con:* Microphone may pick up other small noises and magnify to listner that may cause short discomfort, such as dropping a pen on a glass desk top, microwave beeping sounds, etc.* Being a bit nit picky: bass could be better . . . product price point is low though.
