If exceptional build and sound quality with modern features like wireless connectivity, an app equalizer, active noise cancelling, and a durable design matter to you, the Bang and Olufsen Beoplay EX would be suitable. However, if you're seeking a budget-friendly option with very good sound and you don't mind using wired headphones with a simpler, open design, the Koss KSC75 might be the right choice. Consider that the Koss lacks many features like noise isolation, a mic, and low latency, making it less versatile for varied environments and usage scenarios such as calls, meetings, and gaming. The Bang and Olufsen offer a range of codecs including AptX Adaptive and AAC, support for exercise with sweatproof certification, and longer battery life which could be important for longer listening sessions, traveling, or if you frequently use your earbuds on the go.

"If you’ve wanted truly wireless headphones, but couldn’t pick them up because they sound terrible, these will be the headphones that win you over. If you’re the kind of person who would consider spending $400 on headphones, these are the right truly wireless headphones for you."

"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."
