The HD 250BT shows how Sennheiser - time and time again - hit the sweet spot in every market sector they tackle. It lacks frills (so no ANC) but looks good (shades of the legendary HD 25), seems robust, is comfortable to wear, and pairs easily with the host bluetooth device. The all-important audio quality is first-rate, with well-controlled bass, clear midrange and fatigue-free high frequencies. The HD 250BT is superb value for money, and comes highly recommended.
I have been wanting to purchase a pair of Sennheiser headphones for some time but found that the cost of the products was somewhat above my budget. So I was very pleased to see that this product was being offered at an extremely reasonable price whilst casually browsing online. I placed my order immediately and I received my order within just a few days. The headphones were even better than I had imagined they would be. They are lightweight, have a great design and exceptional sound quality, are easy to use and are very comfortable to wear. I would highly recommend them to any lover of music and tech. You will not be disappointed!
The price with nearly 50% off is just right. It is not too comfy because of the missing pad. With the price of nearly 40,- it's a good entrance for the further product catalogue.
No complains about signal quality or battery life, it's up to what was promised.
Sennheiser sound signature takes some time to get used to, bass is a bit punchy and the sound is less 'flat' than other brands like AKG or AudioTechnica.
What i dislike is comfort, speakers are very small and often move when you speak, eat or just turn the head.
The headband is only rough plastic and start to hurt after a while.
You can't expect much more at this price when the sound is good but it's really a bare minimum when it comes to comfort.
when I saw the special price on Sennheiser site, I decided to take it - light & clear sound - she doesn't want to part of it - however, UPS outsources last km delivery with real morons - the guy rings, enters without asking the way to go to my appartment, sees many entrances son, get out without a phone call
