Sennheiser HD 350BT Wireless foldable Headphones, Black

Actually quiet sonically moved by my first listen to a song that I’ve known for a longtime and listened on every thing from car speakers to soundbar to apple AirPods but on these Sennheiser’s I heard it like it should be heard , like the studio engineers want it to be heard and was actually quite moved. I know the brand Sennheiser having worked briefly in the recording industry when I was younger, they are the makers of professional microphones, headphones and studio equipment so that helped influence my Decision. The clarity and breadth of sound is quite something at this price point . The only slight negative I can give and it’s depends on your music type is that because these are actually for my Son he might find them NOT Bass heavy enough as he listens to Rap. If Bass is your thang then that’s to be considered however if you want audiophile grade headphones with superb build, quality, functions, battery life and above all else sound quality then look no further. 2 year Warranty included if you register.

Some say brands don’t matter but in sound equipment sorry they do. Sennheiser R&D and quality are visible and can be heard in this headphones. Clear not overly compressed sound and good quality ad/da converters. Comfortable to wear even for long periods (I use them for stretches up to 3h in a row). They won’t make you sweat a lot but haven’t used them outside in hot weather. They don’t squeeze your skull and my hears fit perfectly inside, great external sound isolation and easy controls. Great Bluetooth reach. I won’t replace my 600 ohm wired beyer dynamics for these for mixing and mastering but for other tasks that demand free movement these have been the best I’ve had (agains beats, Sony, pioneer and cheap brands).

Soo, I have always been an individual who believes that wires are best with headphones, but as we look at the development of Bluetooth technologies, and the associated codecs that can be used, I think that it is time that the wire free alternative is given a fair try. I am an android user so I had the opportunity to push the bit rate to the upper echelons (unlike the pesky Apple single compression approach) and have to say that I am pleasantly surprised. I think £90 is when you start getting into the market space where sound quality really starts to take on a force of it's own; and here you can really hear the sound Sennheiser are famous for. Generally well extended with brilliant midrange focus. The bass is nice and deep, and the top end is sweet. It allows all kind of music to play with great detail and enjoyment. I don't think that I have listened to a warm pair of sennheisers before, and that is exactly what these are. They trade absolute detail for a decent sound stage and a good presentation. I have one of the last revisions of the HD650, the grand design which all sennheisers have followed, and you can really tell that trickle down of engineering is in full flow....and you can hear the one clear criticism of the hd350. These headphones have been remarked to be a little quiet, needing to be turned up compared to the competitors to be heard....and that is true. They need a little lift.....but it isn't about volume. Compared to the olde HD650 you can hear a DRAMATIC difference in dynamics. The 650s just dig a lot deeper and allow a greater resolve between music moments. They are clearer more detailed, and very very musical with no 'colouring'....so not distortion at all. But the sound that is packed into the HD350 is exceptional value, and that is what (@£90) you are buying. A slice of that amazing sennheiser sound for peanuts. And it is a very unfair comparison, as old as the 650s are they are the stuff of legends; other than the concept electrostatic headphones the HD650 carried the flagship status for absolute years....I cannot think of another product which has stayed available for as long (be it with tweeks), particularly in the audio world. They also differ in approach, with the HD650 being open backed, and these being closed. This could also account for some of the difference in presentation and aids over all noise cancellation for the user. There is no active cancellation circuit (hence the 3 stars) but it is self contained, so does a reasonable job. One other thing that is a little annoying with these is that sennheiser has reduce the band size on their headphones over the years. Where the 650s would comfortably fit over an elephants head, the 350s were fully open for mine.... and you can kind of feel it. Thankfully the sound takes you away from that but it does take a minute to get them to sit round your ears, and you might even send these back if you cannot try before you buy. Sennheisers have become that oddly tight with band size....just an extra inch.... Soooooo, BUY THEM!!!!!!!!

Likes Comfortable, they don't spring hard against your head like other headphones Nice clear sound Bluetooth works really well, connects fast Battery life is a couple of days in between charges for me Fast to charge Nice over the ear cover Dislikes They are not noise cancelling, but idk is that better as from what I have read the noise cancelling can distort the sound, so this could actually be a plus

Good sound quality with a very wide sound stage and big spaces between instruments, bass is restrained but does go deep, sound is very revealing allowing the listener to concentrate on the separate details easily. Battery life is very good, I have yet to flatten the battery after using for over a week for several hours daily. Phones are comfortable and just fit my big head and there is no noise from the plastic structure of the head phones ie no creaking or clonking when moving. These have no noise cancellation but do offer a good degree of acoustic isolation if that is what is required, not really a problem for me. I really can't fault these headphones, they are excellent.

Absolutely love these headphones! Great price point for this type of thing. Sound quality is amazing and functionality is simple. Nice and compact when folded, one downside is that there is no case. Noise cancelling is not 100% but that is ideal for me as I still need to be aware of my surroundings for work. Aesthetically pleasing too, I almost spent 3 x this amount on the equivalent Bose headphones just for the look of them so these were a great find for me.

Beautiful product. Sound quality is signature Sennheiser. Strong build. Battery life is just too good. Headphones are comfortable on ear,but would not recommend to people with big ears. In terms of microphone,I hear a slight echo of my own voice while talking,which is irritating. Could have done a better job. The base is low, but I am more into instrumental music and these headphones have a crystal clear output in sound. They aren't excessively loud which I liked. Noice cancellation is partial. Overall a good package by Sennheiser. I had to check out some settings tips online on youtube for pairing the headphones with other devices,it wasnt mentioned in the manual. Also about how to unpair with old devices. 4.5 stars out of 5.

Excelente calidad y sonido, material duradero y muy cómodos.

Update 06.09.2024: Ich bin absolut zufrieden und habe sie mir nochmal für 59,- € bestellt als Ersatz!!! Auch Spiele können mittels AptX LL USB-Stick ohne merkbare Klangverzögerung schnurlos gespielt werden! Den Klang empfinde ich als gut!!! Bass, Höhen, Mitten, Tiefen, alles da und gut ausgegeben! Viele Tests bestätigen dies und attestieren diesen Kopfhörern grundsätzlich guten / sehr guten Klang!!! Brauche ich weitere Features? Nein: ANC: Nein, verursacht Grundrauschen und jedes Jahr gibt es eine angeblich "noch bessere" Version und ich ärgere mich nur. Klinke: Nein, ich WILL SCHNURLOS und mit gutem Klang Filme schauen, Zocken, etc. und NICHT per Kabel!!! Und ich brauche mir dann auch keine Gedanken machen, ob der Klang per Kabel genauso gut ist... Warum die ganzen neuen Kopfhörer anscheinend gar nicht mehr AptX LL anbieten, verstehe ich nicht... Die Bitrate ist dann zwar bei den neuen höher, aber ob man das dort wirklich im Alltag noch hört??? Eine Verzögerung die bei den neuen dann doppelt so hoch ist (~80ms statt ~40ms) nimmt man dagegen definitiv wahr ("Lippensynchronität")!!! Deswegen: Sennheiser, Ihr habt einen aus meiner Sicht fast schon perfekten Kopfhörer erstellt! Unbedingt kaufen für den heruntergesetzten Preis! Die neuen sind leider nicht unbedingt besser oder wenigstens genauso praktikabel. Egal wie viel Geld man in die Hand nimmt... Oder man hat so viel Geld, um bei Sennheiser einen Individual-Kopfhörer zu bestellen... Oder man nimmt wieder rein schnurgebundene Kopfhörer... Alt: - Es sind mehr on- als over-ear-headphones. Eine passive Geräuschabschirmung ist somit nicht so stark vorhanden wie bei echten overears. - App-Verbindung etwas hakelig. Firmware-Update erst nach mehreren Versuchen / Kopfhörerzurücksetzungen erfolgreich. Sobald die Kopfhörer jedoch zuerst mit dem App-Gerät verbunden sind, funktionieren die Einstellungen. - Nicht gerade die lautesten Kopfhörer. Aber ich muss auch bei lauten Hintergrundgeräuschen trotzdem nicht auf Maximalvolumen gehen. + Klang ist ordentlich. Relativ neutral. Bass nicht aufdringlich, aber vorhanden. + Equalizer-Einstellungen aus der App werden in den Kopfhörer übertragen. Dort habe ich die Tiefen komplett aufgedreht, weil ich einen "wärmeren" Klang bevorzuge. Die Einstellungen bleiben also auch z.B. bei der Verbindung mit dem PC erhalten. + Telefonieren funktioniert gut. Bin ordentlich verständlich. Der Transparenzmodus, wo man sich selbst hört, kann per App in zwei Stufen aktiviert oder auch komplett ausgeschaltet werden. + Im Vergleich zu Mitbewerbern (außer man geht in die 400,- € - Liga) ziemlich viele Codecs vorhanden. Auch aptx ll. Wobei Android (oder amazon prime?) anscheinend die Synchronisierung bei allen Codecs inzwischen gut hinbekommt. Zumindest hatte ich bei einem Test mit einem prime-Film weder mit aptx ll noch mit sbc (anderer Kopfhörer) eine große Latenz bemerkt. Und Windows schafft aptx ll leider nicht => somit hilft der codec einem dort leider nicht weiter. Aber man darf ja hoffen, sodass das vielleicht später mal kommt. Und es gibt ja auch externe BT-Sender, welche aptx ll können. + Gleichzeitige Verbindung mit zwei Geräten funktioniert, wenn man beachtet, dass man auf dem einen Gerät manuell die Tonausgabe stoppen muss (Musik / Film anhalten) bevor man aus dem anderen Gerät etwas hören kann. + Echte erfühlbare Tasten, keine Touch-Bedienung + Auch mit Brille habe ich keine Probleme, wenn ich die Kopfhörer mal mehrere Stunden aufhabe, wobei ich in dem Bereich nicht sonderlich sensibel bin. Fazit: Bin zufrieden mit dem Dingens. Ich glaube man macht damit nichts falsch zu dem Preis. Tipps: ° Für Windows lasse ich mittels lav-decoder und dortigem negativem delay von ca. -200 ms die Synchronität von Filmen wieder herstellen. Klappt nur leider soweit ich weiß nicht für Spiele oder Webseiten wie youtube. ° Für einen ordentlichen Equalizer unter Windows mit vielen Möglichkeiten unbedingt mal Equalizer APO ansehen! Dort lässt sich beispielsweise der Bassbereich so hochdrehen, dass es schon zu drückend wird.
