The microphone for the headset is not the best. They often complain that you are talking from an "iron" can. The codec is far from the best, hence the sound is mediocre. They can fall off when watching a movie when switching series - it strains as much as cracked plastic (new headphones are rewound with electrical tape). Sennheiser hd350bt, purchased after cracking philips, showed an order of magnitude better sound quality, two to three times longer operation. And after comparing these positions, I definitely do not recommend philips tah5205 for purchase. Especially after the price increase.
