If you prefer earbuds and prioritize sound quality and build, the Moondrop Blessing 3 is a strong choice, but keep in mind, they lack wireless capabilities and have poor microphone quality. Conversely, the Sennheiser HD 400S offers better value, very good comfort, and microphone quality, making them ideal for calls and extended wear. The 400S are over-ear headphones with good sound, however, their enclosure may not be suitable for exercise and they don't support wireless use. Neither option has active noise cancelling or low latency features, so for activities that require noise isolation or sync precision like gaming, alternatives may be required. Give Feedback

"The Moondrop Blessing 3 has excellent imaging performance, especially for the price. Pair that with its neutral tonality with slight elevations towards both ends of the frequency response, and the Blessing 3 technically proficient set of IEMs that are also enjoyable to listen to every day."

"Sennheiser has done it again. The HD 400S performs well beyond its price range and is one of the better budget model headphones I’ve tried. It has very few bells and whistles and offers a simple means of listening that still delivers amazing clarity and quality. If you need a good first pair of headphones or need something that you can take out of the house, then the HD 400S is definitely for you."
