Sennheiser HD 350BT Wireless Bluetooth Over Ear Headphone with Mic for Music & Calls, Desgined in Germany, 30h Battery, 2 Yr Warranty (Black)

The Sennheiser HD 350BT has been my go-to headset for over four years now, and it continues to impress. The sound quality is top-notch, delivering rich, balanced audio with deep bass and clear mids—perfect for enjoying all kinds of music. The Bluetooth connectivity is seamless, and the battery life remains strong, making it an excellent choice for long listening sessions.What truly sets this headset apart is its durability. Even after years of regular use, it still performs like new, proving to be a great investment for music lovers. Whether at home, commuting, or traveling, it’s been an incredibly reliable companion. I can confidently say that Sennheiser has nailed both quality and longevity with this one!

Here's the TLDR: gets uncomfortable after about an hour of use if you have big ears like I do. Sounds pretty good considering the price, slightly on the bassier side, but fairly neutral overall. Best in the price range I think, at least compared to the offerings from JBL. The marshall major 3 wireless has better sound, build quality and comfort but doesn't have the voice assistant support. Skip to the last for the scores.Allow me to explain in detail:THE SOUND:It sounds good. I love Sennheiser's sound signature and this one has been tuned to have a very slight bassier curve. Bassheads won't like it i suppose. Upper bass range sounds a bit muddy to my ears, though only when listened very closely. Most users won't notice it i suspect. The lower highs could use a bit more punch. It does struggle a tad to produce the very high frequencies (12khz+). I'll be honest, i do like my listening headphones to be a bit on the beassier end but I absolutely hate the way Skullcandy, Beats etc achieve that. These, however, have quite an enjoyable sound signature, especially once you tweak your eq. The headphones respond really well to eq tweaks, especially inside the Sennheiser app (the app doesn't offer a parametric eq but it does have a eq thing that lets you move around a dot and tries to adjust the eq accordingly.)The sound stage is okay and the imaging is quite good. Instrument separation is fine for the price.COMFORT AND BUILD:The build quality is good. It's all plastic but the plastic feels solid. No complaints there.However, the headphones are small for overheads. It might be just me though as I'm only really familiar with overhead headphones like the M40x, M50x, some AKGs, Beyerdynamic etc, all of which go well over the ears and are incredibly comfortable (the ATH M series NEED the Brainwavs earpads though) and all of them have a nice and gentle clamping force. Anyways, back to this pair.The earpads are not memory-foam and the sides are unnecessarily wide, thus doesn't leave much room for the ears inside. Since I've big ears, the pads rest somewhat toward the ends of my ears, which makes them uncomfortable for longer sessions. However, the clamping force is not bad and that makes the pair relatively pleasant. I say relatively because the JBL LIVE 500BTs have a clamping force of 0.7kg (vs only about 0.2kg of these. as per testings of rtings.com), which feels like getting crushed under a rock.The earpads are replaceable so I'm hoping that brainwavz will release some really nice and plush pads for these headphones, which should improve the comfort further. These aren't bad the way they are though. If you have smaller ears, i think you'll be perfectly happy.UPDATE: The regular brainwavz pleather pads do fit these just fine. It makes them incredibly comfortable. Although the earpads are a tad oversized but it doesn't come off or wiggle or anything like that. They make the bass response quite weak though. Pick your poison i guess.Tip: turning the earpads about 30° (may vary) clockwise may improve the comfort dramatically.MISCELLANEOUS THINGS:Battery life seems to be excellent. Noise isolation is passive but it does a decent job.VERDICT:I think they're worth the price and better than the competition. They're built well and they sound decent. They don't have some bells and whistles like audio passthrough but it has either better comfort or better sound quality compared to those. The inclusion of a type c port is nice. AptX low latency support is great for Android users. Overall it gets my recommendation.SCORES, WITHOUT CONSIDERING THE PRICE:Sound: 6.7/10Build: 7/10Comfort: 5.9/10Battery: 10/10Bluetooth range: 9/10Bells and Whistles: 5/10

Sennheiser is reputed brand mainly for the mic and headphone for recording in studio and PA systems. If you need the pure and accurate sound reproduction this HD 350BT is some best, however a wired headphone is more recommended for studio recordings. This HD 350BT Wireless Bluetooth is not for music entertainment if you desired for heavy bass and trebles. It's noise enhance (not reduction) has superb active when you peak a call over the mobile phone. This is truly a waste of money product and I bought this by mistake on he name of the brand quality reputation. Only one thing is good that it's design and best covering ears. It looks best but works as local. It's not for music enjoy nor for peaking call over the mobile it's just for listening as it as original recordings.

The audio quality on these headphones is pretty decent and they are not too heavy on your head, but there isn't a lot of padding on the headband, so you might feel somenirritation on the head after prolonged usage. The ear cups have good cushioning but their size is quite narrow, so big ears might have a little problem there.My main problem is the connection, though Bluetooth works great and seamlessly connects to my devices, there is no option for wired listening (no headphone jack). This may not be on everyone's checklist, but if you want low latency, a headphone jack is required. While gaming there's a slight delay, so it may not be the best for competitive gamers.Overall, it's a good headphone for casual listening but it can be much better as there are pretty good options other than these at the same price range that have a headphone jack with noise cancellation.

First when I ordered I have received a tampered package and I have returned.Thanks to amazon for replacing it with another one. After opened the package struggled alot to connect to android and Iphone. After multiple phone restarts it is connected . For Android smart phone it is not connecting via app but bluetooth only. Tried alot but keep in trying sync but not successful. It is heavy doesnt feel like to put on head for long time. Ovel shape and not properly fitting on head .battery is good as per my experience in a day.buttons are not convenient to operate.whatsapp call alert was not functioning for android phone but only I phone. The call answering function not working properly, sometime it says call ended but it still connects the call. Apart from comfort and technology, very disappointed with sound quality. Not for music lovers. Missing the bass punch and clarity in the music . Doesnt seem like sennheiser product ... as Sennheiser’s expected quality is not given in this product.any normal brand can give better quality than this.Ear cups are soft and high quality.over all I would not recommend to go for this product and also I have realzied that purchasing online is not that great than direct from showrooms.
