High sound fidelity and great connectivity (even through walls or at a big distance (about 20 feet before losing connection. Noise cancellation is very good, you can hear a lottle outside noise which is sufficient for safety. Very high quality build and cushion specially to wear during work day or long gaming sessions. About 400ms audio delay when connected to phone, this can be avoided via aux cable. Easy to connect to. Previously bought version 440BT and they are still working just as well over 7 years later.

Comfortable and great for the plane or lawn mowing

Great headphones with awesome sound! Versatile too, You can bypass the bluetooth wireless and plug in the optional wire if you need to. I love these headphones!!

erg fijne koptelefoon! voor een goede prijs!

Credo che siano delle ottime cuffie, una traccia lossless è distinguibile da una lossy. Suono ben equilibrato di default da 20hz a fin dove arrivo (circa 17k hz). Arrivano fino a 20k hz. Equalizzatore tramite app abbastanza rudimentale che permette di agire su bassi-medi-alti con una decina di settaggi ciascuno. Pulsanteria efficace posizionata tutta sotto al padiglione destro. Non mi è piaciuta la custodia, molto economica, che non protegge da urti perchè morbida e sottile, utile comunque la tasca interna per portare i cavi di ricarica e jack. A proposito del jack: è un adattatore maschio/maschio da 2,5 a 3,5. Il suo difetto è che non porta l'audio del microfono ma solo quello dei padiglioni. Speravo di poterle utilizzare come headset per il pc da collegate, ma l'adattaore ha da una parte 4 poli e dall'altra 3 (gnd, audioL, audioR). Peccato. La cancellazione del rumore è buona. Se vi aspettare di poterci dormire in un sottopassaggio ferroviario lasciate stare, ma se vi serve attutire del brusìo vanno bene. Mi pare di notare che sia molto efficace nell'eliminare tutti quei suoni che risuonerebbero in cuffia, che per come le sto utilizzando sono medi e bassi tipo le voci di persone che vi parlano. Per gli alti passa qualcosa in più. Per darvi un'idea, se ascolto musica e qualcuno mi parla devo leggere il labiale. Forse avrei preferito un po'più di isolamento passivo ma siamo a buoni livelli. Direi che per 100€ sono soddisfatto.

I've used the 4.5 BT headset for quite a while & it's a very good headset. The audio quality is great, the quality for phone calls is very good also & adds a lot of convenience for calling people while walking or multitasking, not having to hold anything in your hand. The headsets band can be a bit uncomfortable for some people.. I'd say when I first got it, my head almost felt sore from it after a few hours of wearing it. I haven't felt that soreness for a long time though now, I guess it's like riding a bike with a new seat & feeling sore when you first use it but eventually becoming used to it. I use the headset for gaming on my PC & video/voice conferencing on it also for work. I also use it for pairing to my smart phone which I use mainly for listening to music, but again for phone calls at times too. They are Sennheiser, so I don't need to talk about the audio quality... Sennheiser don't make anything but top tier audio quality devices. I would and I have recommended these headsets to people before, my ex gf even wanted a pair & asked me for advice so I recommended she get this pair & she did. My cups wore on my headset after a while as well, but this is because I was using them a lot in summer and sweating & putting my sunglasses on while I was already wearing them, I think the sunglasses caused the seams to tear with the cups. It was no problem though, I ordered replacement cups & they fit on with ease. I've ordered some extra cups too for later down the line when I will eventually need new ones (all cups for all headsets wear over time) Adding the new cups was amazing, it felt like I had a brand new headset again!

テレビで動画（PrimeVideoやNetflix）を視聴するために購入しました。低音と高音のバランスが良くクリアな印象です。ノイズキャンセルも効いてて周りの騒音はほとんど入ってきません。aptX-LL対応なので、対応トランスミッターとの組み合わで音と映像のずれを全く感じません。コスパが良いと思います。ただし難点をいえば、操作ボタンが小さいので少し操作しづらいことです。

Bon son.
